Ok here's one for you guys... the fans on my e36 are terrible when the air con is switched on. It's a 1999 318is with auto climate control.

I took it to kwik fit to be re-gassed. It blows nice and cold but the airflow is next to nothing when the a/c is on - to the point where it's not worth having the a/c on. When you turn the a/c off and have it running just on normal fans, the airflow is fine!

I've checked the pollen filter, which is fine. I even ran it without the filter in to see if that would make a difference - nothing.

The fan motor goes up to top speed fine so I don't think it's the final stage / hedgehog resistor it's just when you turn on the a/c the airflow drops right off (you can hear the fans stay at the same speed).

Any ideas?? Cos this is driving me insane!!! :banghead: :cheese: :wtf:
