airco A/C light flashes

The flashing green light in the A/C button indicates trouble. However a refill and very expensive presurising of the system did not solve the problem. Who knows a solution. The Camry is a 2.2 GL 1998.

(just guessing here) a bad compressor, or a leak in the system?

Not sure I understand all this, but thought it might come in handy some day, so copied and saved it at some time in the past. These are not my words, but hope they may help you. ================================= =================================

You forget to mantion one more item, the A/C clutch is slipping. The A/C AMP senses this and disengages the A/C clutch and flashes the light. This is usually caused by the wearing down of the clutch surfaces and the gap becomes too wide. Fortunately, the gap can be adjusted by removing shims from the shaft of the compressor where the clutch plate is attached to. Measure the gap using a dial indicator, feeler gauge would not work with this compressor because the clutch plate is recessed under the pulley. Using a jumper wire to connect the magnetic coil to the battery to engage the clutch if you work alone. The normal range of the gap is 20mils +/-5mils.

You can remove the compressor without disconnecting the hoses, but the radiator hose above it has to be disconnected so that the compressor can be lifted up to gain access to the clutch plate screw. Drain the radiator fluid first. Use wires to hold the compressor with the clutch plate facing upwards. Use a locking plier or C-clamp to hold the clutch plate to the pulley to prevent it from turning when you unscrew the center bolt. Becareful when lifting the clutch plate out not to loose any of the shims.

If you measured the gap at 40mils, just take off the number of shims close to 20mils and reinstall them. Now you gap should be 20mils. Verify this with the dial indicator before you put every thing back.

If you find deep grooves on the clutch plate surfaces, it is better to replace clutch completely. The clutch assembly should not cost more than $70 at you local Pep-Boy store.
