Thanks BIGRR, but my resistor pack looks like this one - it's mounted in with the fan.

They are not resistors they are transistors same as in a Xantia
They are cheap to buy as an individual item and replace
That is to say from a place like Jaycar
They can be easily tested with a multimeter
I had the same symptoms on a Xantia and replacing the trannys worked
