2003 A/c Clutch Issue?
Posted 28 July 2012 - 03:23 PM
The A/C on our 2003 Corolla has been getting warmer lately. I decided to try and recharge it myself. I think I followed the directions, and brought it to about 50 PSI at 90 degrees ambient. This didn't seem to help. I then noticed that the clutch in the compressor is not staying engaged for very long. It makes the clicking sound, and engages, but then disengages after a few seconds. Then after a few more seconds it will click and engage, then quickly disengage again. Could this be a sign of a bad clutch?

Question - how low was the refrigerant before you charged it? Was it a little low, or very low? Made sure to was the R134a refrigerant - as some shops may accidentally have older, non-compatible stock still on the shelves?

Also possible that the clutch on the compressor is slowly dying. Low RPMs might not generate enough centrifical force to expand and engage (assuming electronics work). You can try to fast idle / rev the motor for a short time, while stopped to see if compressor fully engages.

Many 9th gen owners that did this mod saw significant A/C performance improvements at low speeds or at idle. Might be something to try out if everything else seems to be fully functional.

The cabin filter was little mucky, but not too bad, and the air blows hard thriugh the vents.
It does seem a little odd they don't insulate the supply pipes, but I guess efficiency isn't a concern there.
