About a year ago I had nearly all of my A/C components replaced(compressor, accumulator, hoses, orifice tube, etc), it cooled fine through the summer then quit sometime in the winter. I figured there was a leak so I gave it a charge up and it cooled fine for about 3 weeks. Now its not cooling and I checked to see if it was a leak again but the pressure is right where it should be. Compressor kicks on fine and the pressure hovers about where it should but it doesnt cool at all. Any suggestions as to what the problem may be and what I can do about it? Thanks

 

What are your High & Low pressures? Are you sure your not over charged? R134A if over charged won't cool. Is your condenser dirty or plugged up?

 

blend door ?

 

Let's look at the basics. Does the accumulator get cold? Does the AC clutch cycle at all?

 

The accumulator does not get cold, but the AC clutch does cycle.

 

How long does the clutch stay engaged?. If under three seconds, Remove the connector at the ACCUM cycle sw and sjump those sockets.
Does the Accum get cold, then?

If you are using the gauge that comes with can, they are crap.. what do you expect for costing about a buck to make.. and cant be trusted.
Not saying that's the problem but You cant give us numbers in PSI as to when clutch engages and disengages can you?

 

Yes, it is engaged for under three seconds. Engages at 55 psi and quits at 15.

 

and yes the accumulator does cool slightly while the connector is jumped. Slightly as in the air coming out is no longer warm but still not Very cool or cold.

 

With out Hi & Low pressure readings every one is just guessing.
