Whitesupraboy2 Posted March 1, 2004 Share Posted March 1, 2004 I done the air con diagnostics thing....and well im not sure wat i have to do to be honest. I had the fresh air switch and the Defrost mode switch both flashing alternatively. fresh air is pressure switch relay- Could this mean out of gas?? Defrost switch - means Solar sensor? Basically im asking anyone with any slight techinical knowledge, what they think as electrical aint my thing. If sounds like may be gas ill go get it filled up cheers James Link to comment Share on other sites More sharing options...
toyotasuprauk Posted March 1, 2004 Share Posted March 1, 2004 Did you receive the PDF? The flashing of the defrost light is normal you just need to shine a very bright light on the solar sensor on the top of the dash board to turn it off. The pressure switch means the gas levels are too low to safely run the air con without causing damage to other parts of system so it shuts off as a fail safe. I'm betting if you turn on the air con whilst the engine is running nothing happens to the revs, and no cold air comes out etc. I'm not an expert in car air con but I would say if you had it regassed which I think costs between £40 and £60 then reset the system it would go back to normal. I need a regas too and mine does the same thing. Link to comment Share on other sites More sharing options...

DO NOT try and be clever and short out the safety switch, you will seize the compressor up through no oil flow. Link to comment Share on other sites More sharing options...
