    Default My "new" CX coupla things to be sorted

    Tragic here, as well as having a BX, I have now splurged on a 'dead' CX. The crank angle sensor was kaput, ordered a couple from Darrin at Citroenclassics in late Nov. They arrived a couple of days ago. They are the Ford ones, model 6502253 and it is thanks to Shane who kindly replied to my query a couple of months ago (see CX2400 crank angle sensor). And they work, though the anchoring will have to be sorted out. The car started, and rose. The car is a CX25IE early 1985 auto.
    Now, I am new to CX here, folks, a couple of things ain't working. The driver's electric window is not rising. Most likely fix would be?
    Driver's seat not reclining or raising/lowering.
    Which Dexron is the more suitable for the auto box (3HP22)?
    Will try to post a piccy later,
    Cheers
    Lou

    Maybe see if you can swap some switches around for the drivers window. The seat issue seems more like a power or earth problem so see if you can find a blown fuse or test for power and connection to chassis on the wiring to the seat system. (electric seats on a CX - never heard of that before)

    Cheers, Ken

    For drivers side electric window, if swapping switches doesn't work, check for broken wires where loom goes from the body to the door.

    Good call! and the relays around the battery if you have recently changed the battery (the plugs often get knocked off).

    The battery is the same, no change, ran the engine yesterday to see if the cooling fans came on. They didn't. Wiil check a few thaings later this week (car is several k's from home and can only attend between shifts). When engine off and keyy removed the battery charge light is on. Engine running - the light is off. Do I need a new alternator?
    Driver's seat is not electric - just a stuck raising mechanism.
    Dexron 2 or 3 for the 3HP22?
    Thanks for your various replies.

    Lou,

    Sounds like a relay is stuck on (or shorted out) for the alternator light to be getting power when the ignition is off. The fan relays are probably suspect as well. You can check these without running the engine by disconnecting the wires to the temp sensor on the radiator and shorting the low speed/temp lead to earth and then shorting the high speed/temp to earth as well.

    I would pull all the relay connectors off one at a time and check for burned spades and sockets and clean with contact cleaner so they get good contact.

    Take the seat out to fix the lifting mechanism.

    Cheers, Ken

    DEX 2 for the transmission. Also known as Castrol Transmax M. Don't let the spotty youf at Repco tell you different.

    I agree re the wire in the door - ours had the same problem. It was either slooooooooooow or non functional. I repaired the partly broken wire and it worked.

    Does the window go one way and not the other?

    Thanks fellas, have noted your tips/advice. Am currently 'at work' and won't be able to visit the CX until saturday arvo at the earliest. I have not yet tried the driver;s window. It is down so I left it like that as the garage bloke also tried it - no go.
    The original crank angle sensor which was 'dead' = filed a half mil off the end - there was no shim so it was contacting the flywheel teeth. Exposed some of the coil, put it back in for 'look see' and the engine fired up. So- if your CA sensor is 'dead' either file a bit off the end or increase the shim thickness and give it a try. I have a theory.....
    As for the gearbox, there was ahalf empty Dexron 3 container in the boot. Will scout around for the D2 stuff or equivalent.
    Am trying to rescue this beautiful old French girl and get her back on the road. Will eventually need a complete binacle, most console parts, a carpet, dare say a driver;s seat - the leather is falling apart, roof lining (how does it come off?). But the body has minimal rust as it had been garaged nearly all its life.
    Cheers

    The later roof linings attach with plastic clips just like the door cards. They are difficult to remove intact.

    The roof linings let go as the foam between the fabric and the glue on the inside of the roof perishes. I suppose an auto trimmer could repair/replace by putting those rod things inside a new lining.

    When you find the ATF get about three x 4l containers and do a gradual change over a few weeks.

    Classic ATF is a Dexron 2 mineral fluid as listed by Penrite, but only held in very small quantities apparently. So, it will vey likely be a special order and that means you are up for a box of 4 x 5 litre containers.

    A problem with one of my old cx window was the grease had gone hard around the motor drive screw.
    Whilst cleaning the switchs and checking for broken wires,pull the motor out,take off cover and clean
    old grease out,re-lube and it might be good.

    Thankyou for the many replies, have again checked the car and found a green wire broken at the driver's door to body space. Suspect that it is the reason why the electric window is u/s. Will reconnect in dues course and report.
    The alternator is a Bosch looks fairly recent. I did find along green wire coming from the lhs fuse box to near the battery - the wire was floating freely in space.
    I also found on the battery terminal nearer the hp pump (the +?) a yellow connector that had a broken wire broken off it.
    How do I replace the front parking/blinker bulbs? (series 1 CX with stainless bumper).
    The radiator 'bottle' took at least 1 and half litres of green stuff and could possibly take more. Is there a max/min level indication?
    The 'bottle' had brownish gunk in the bottom - can the bottle be removed and cleaned?
    The car started again with the original CA sensor I had filed down, she rose beautifully, but each front corner is rather hard on the push down test. The rear corners are ok. Which seems like it needs new front spheres, given that it was last on the road in 2013 that is not surprising.
    The coolant temp indicator does not seem to have a needle. Am I missing something?
    The engine, while it did run, idled slowly - about 550rpm. And seemed to idle/run a on the rough side. A 'blat' on the accelerator and the engine accelerated then couldn't regain idle and died. Am loathe to remove any engine bits at this stage as the car is to be moved before chrissy, preferably under its own power.
    Cheers

    Front bulb replacement - BEWARE this task means dealing with possibly brittle plastic. The units are spring-loaded and held in place by plastic locating tags on each side of the unit which lock it into the bumper. Push the light back gently, wiggle it side to side and you'll be able to see the locating tags. Use a flat-bladed screw driver to gently push the tag toward the unit until it clears the bumper, the spring loading should then push the unit forward so you can remove it from the bumper. The bulb holders (on 2400 models at least) are also held by possibly brittle plastic clips, you'll see them clearly once you've got the unit free of the bumper.

    G'day Lou,

    Congrats on your acquisition.

    Re. Cooling system header tank, yes it is removable. As with most old cooling system hoses though, take care getting them off. If the tank is that dirty, you may wish to consider cleaning the rest of the system sometime.

    Temp gauge: is the needle hiding down the bottom perhaps?

    Rough/not idling: air leaks downstream of the air flow meter can cause issues similar to your description.

    Good luck !

    More hints- thankyou.
    Update: I took out the battery, charged it, placed out side and ran a jumper lead. The terminal clamps became warm. Resistance, short somewhere, which depleted the battery in 2 minutes. To the point ruining the battery. Suspected the alternator diodes. Disconnected the alternator cable and taped it. With another full battery slotted in place and using the original crank angle sensor which I had ground down a little - the engine fired up. And stayed running for 16 minutes before I was satisfied that it seems ok. It wasn't running roughly, though. And accelerating was reasonably smooth considering the petrol is probably a few years old.
    While running I added about 4 litres of coolant. It was dry. The cooling fans also burst into life. Relief. I discovered a small hydraulic leak under the huge cross member - steering rack leaking? The auto gearbox took a litre of Dex 2 (which I had on hand as I also have a BX auto and have sourced 5litres of Penrite Classic ATF). The drivers electric window revealed a broken green wire which I soldered. the window now goes up and down. Another relief. Next step is to remove the alternator. And have it repaired.
    I tried to remove the LH headlight, undid the plastic thingy on to but the headlight doesn't budge (1985 model so should have only 1 thingy). What am I missing? The interior is black - not my cup of tea and the instrument binacle has been played with. It is rather messy. With Black paint over brown, the paint scratches off. Ugly. The temp gauge needle has gone missing in action, no where to be seen, can't see it at the bottom. Same with oil level/ temp (?) gauge - no needle there either. Have yet to check if these gauges are connected. Am delighted that she runs, albeit with cactus alternator.

    Coupla questions: is there a relay for the alternator? (I am zero in car electrics) If so, where?
    And, is the steering rack the same as for other series 1 models?

    Took it a spin around the garage car park yesterday. It goes, gear selection (auto) is clunky, what could be the cause? I did put a litre of Dex 2 in it before and suspect the po had used Dex3.
    Brakes work, though discs would be rusty as car hadn't been driven for maybe 6 years.
    The alternator was disconnected and the car ran well just off the battery, let it idle for 45 mins. No overheating.
    The front blinkers were successfully removed and cleaned, bulbs tested. Thanks for the tips
    Still would like to know if there is an alternator relay, and where would it be?
    Regards
    Lou

    Hi Loudel,

    I'm not sure exactly which model you have but based on the most probable wiring diagram I found, you have an alternator (black wire to battery via starter & yellow into loom) with an independent voltage regulator mounted (in front of?) the battery - three wires. There doesn't appear to be any relay. Based on what you've written previously, maybe it's worth getting your alternator checked out by an auto electrician (or even swap it for a new/recon unit)..?

    As an aside, being a sparky is what allowed me to afford the luxury of CX when I was still at university all those years ago. Back then, you could pick up a really nice CX for pennies because the owner (and local Citroen dealer) had given up trying to solve a problem that normally boiled down to bad earths, dirty contacts or (more rarely) failed electrical components.

    Several of us have fitted Bosch universal alternators with built in regulators I think to replace the old and rare (in Oz) French ones. It's a good conversion, there's a lot to be said for a brand new item and the Bosch alternators are common. 120 amp capacity is available..... You do have to be very careful about clearance between the alternator adjustment bracket and one of the radiator hoses however. If you go that way shout and I'll send photos of the hose modification that gets around it for the C-matic version with the transmission oil cooler.

    Relay? What for? My ambition is only to know the horrors of the CX relay system as and when trouble arises.
