    Default 306 Cooling Fans Control Unit

    Hey Team,

    2001 306 XT 2.0L

    Advertisement


    Fans aren't coming on when at 100 or even when air con is turned on, and it's been suggested it's the fan
    control unit, found under the passenger headlight inside the bumber.

    It's a $125 part to buy, so before I do, penny for your thoughts?

    is one only coming on?...they run in series for low speed, so if one motor is out no fans at all, then 1 only comes in at full speed...the brushes in these motors go all the time (a xantia a 306 and a 406 I owned ALL of them has this happen)...I get brushes from an auto electricin and cut them to size for about $10...they bastards to get out tho, I cut a double ended ring spanner in half to get to the rear 10mm nuts, then you have to pull the "non rebuildable" fan motor apart...

    Unfortunately, it's no fans at all. Good to know about the brushes though. Thanks.

    did you do the test where you remove the green(I think by memory) connector on the thermostat housing and turn the ignition on and the fans go slow then fast to test all is working?

    good explanation here

    also check the fuses.
    it will be one of the fuses under the bonnet on passenger side.
    If one of the motors is gone, they sometimes blow the fuse.

    check to see if the fans come on with the ac switched on. if yes, look elsewhere. if no, replace the control unit, then the fans. after your standard power/fuse/relay checks
    The wrong oil is better than no oil at all.

    Hi there,

    I was having trouble with the fans on my 405 SRDT when this link was posted for me.

    It may be of assistance for you perhaps.

    Ok, so I've made some progress. I changed the control unit over, turned the air con, but no fans. I was gutted. Then... I turned the fans by hand and hey presto, fans started spinning. So happy. So, it may have been the control unit, but until I put the old one back in, I won't know. In the meantime, I gonna hope it's the brushes being temperamental and not the bearings that are "seizing" the fans. Shall update ASAP.

    Does anyone have advice on getting them out?

    You'll have to remove the front bumper and grille. I have prepared a repair data sheet on the fans which I can send you if like. It's an MS Word document.

    Email me at [email protected], and I'll send it to you.

    This is a sign that the fan motors are on there way out, so I'd say your old control unit is still good.

    To change the fans, you'll have to remove the bumper and grill (as already mentioned).
    This is tricky because its vary easy to brake the plastic clips around the grill and headlights.
