Air Con Fan Switch

[marinabrid]

hi all

on the mk1 tdi can anyone tell us where the switch is that turns the twin fans on that are mounted to the radiator or does anyone know why when the air con is turned on and the compressor kicks in the twin fans dont come on as they should thanks

Arent the fans on the radiator just the cooling system fans? On any other car the radiator fans are for the cooling system not the A/C.

They should come on at roughly 3/4 way up the temperature gauge.

not on this galaxy ! normally when you turned the ac on the fans also start whatever the engine temp mine seem to have stopped for some reason

both fans still run to cool the rad though? Edited April 22, 2007 by wolfie

Yes, do both fans kick in if the engine temperature is too high?

You are right Martin certainly on the diesel models and I would suggest on petrol models the fans should cut in when the air con is switched on. The very nature of how air conditioning works requires that air is constantly passed through the condenser (radiator) to convert the high temperature gas back into a liquid.

 

I would also add that to see the fans running on a diesel engine because of temperature, you would have to be stood in a traffic jam with temperatures in excess of 25C.

 

i am sorry that this does not answer your original question, but are you sure that the compressor is running. I have had similar problem with low gas. The sensor prevents the compressor and fans starting when the air-con swith is pressed although the orange light comes on as if it is working.
