Air con
 

Dont know if this is the right section....but aircon light comes on but revs stay the same,what could it be.?Thanks

Don't always change, is it actually working?
I.e does the compressor wheel turn??

Dont know where the compressor is in the engine compartment?Theres no change in revs or any switching noise-just nothing apart from the light.

Look where washer fluid bottle is, right down bottom towards front of engine
No turn = not working or out of gas, etc etc

Ok thanks,i'll check tomorrow after work.Would no gas stop it working then?

Yup!

Mk2 wont let the aircon run if the outside temp is too low.
