Title: Lots of fan questions - help needed....
Post by: SafferYork on 13 March 2017, 11:00

Hi all.

My fans have not worked since I owned the car - 6 months.

I've done a number of tests - powered up the fans directly (they run) jumpered pin 1 to pin 2 on the temperature sender (runs at low speed) jumpered pin 2 to pin 3 with ignition on - does NOT run at high speed.

The fans are not running at all, ac on, ac off (note here - the ac doesn't work either - clutch isn't engaging).
Could this be the fan control module that is needing replacement?

Any help would be greatly appreciated. And, yes, the fuses have been checked - 40amp, 30 amp in the engine bay and fuse 16 in the cabin.

 The a/c is unlikely to work if it is out of gas...all the systems I've used wouldn't, but a re gas fixed that.

Can't help with the fan situation...sorry.
