Thread: AC problem

thanx for the imput guys,i ran your post by my brother via the telephone, and he says he added 2 lbs,which should be enough to kick the compressor on even if there is a leak.but it wont kick on at all,which is why he wouldnt add dye (ive got nothing to push it through the system).he advised before i go ahead and go leak testing,and replacing the accumulator and such to just have a mechanic take a look. ..

THe one thing he didnt know about was evap core (not sure about automotive i guess)Could u tell me more about this by chance?

Thanx guys.

Thanx guys.

The evaporator core sits inside the cabin right behind the heater core. If that is the source of the leak when nothing else is detected, the only way to tell is to tear that apart. It's a pain I must warn you.

On some cars you can jump the low pressure switch on the line and force the compressor to start. Sometimes that will also keep it from kicking on.

If you retest the pressure in the system and it doesn't show a charge, then you still have a leak somewhere, and just need to find it.
