Teckee question.

 

My aircon is not blowing cold, just pushing in ambient temp air.

 

turn on aircon, revs pick up ok but no cold.

 

done the test in an earlier post: windows down aircon on full wait 5 mins and check for bubbles in window, no bubbles.

 

Its been in for a service recently and the mech said he could hear a 'whine' from the bearinbg or 'clutch' (!?) on the aircon pump.

 

I've also checked the obvious fuses, seem ok.

I tried to listen to the rlay to make sure it was switching but cant hear it, altough I cant hear the headlamp relay either.

 

Any thoughts before I get a proper mech to diagnose. Bugeer its hot at the moment! Excuse to tkae the roof off!!!

Did you check if the compressor is turning?

You have to look at the front of it. It should turn and stop repeatedly.

 

Were the no bubbles at all? Maybe you've got no gas left?

Check for bubbles at 1500RPM.

 

Just some ideas.

since i had my engine rebuil my aircon is not working, how do i diagnose this lot

Hi, mine's just been in for a service and I have had the aircon diagnosed as a problem with the compressor. It too would just blow tepid air, no bubbles etc. I had previously has it gassed and was told that it just wasn't holding the pressure therefore a leak somewhere.
