I've just installed a new Z20LET into my Zaf GSi.
When the car is standing with the engine running, the air con fan comes on and the coolant/air con light comes on, on the dashboard.
I had a guy out today to regas the air con system and he said that the compressor has gone and needs replacing. He said he had sorted the fan problem by cleaning the pressure switch.
However, the fan and light still come on after the car has been stood for about 10 minutes with the engine running.
The fan will be on for about a minute or 2 then it goes off, after 5 minutes or so, the fan comes back on.
The dash light comes on and stays on.
Anyone got any ideas?
