a/c light blinking 98 camry

Okay,
Yes I changed the magnetic clutch relay. Still the same problem. The air conditioner works for a minute, then the cold air stops and the light blinks (it taunts me).

How is the pressure? Have you cleaned the sensor connections?

Have you checked the A/C belt for proper tension? The blinking can be caused by something as simple as a loose A/C belt slipping on the compressor. Once the belt slips, the compressor shuts down and the light blinks.

there's a possibility it is low on refrigerant and the low pressure switch is cutting it off. Check for the A/C operation at the A/C amplifier:

The A/C system pressure switch and cabin thermisistor come into this controller as well as engine temp ECT sensor and the output is the control to the A/C clutch relay. You can pretty well check A/C operation from there and then determine where the fault lies.

Don't know what engine you have, so there will be differences here.

The A/C clutch also has a 'lock sensor' that the A/C amplifier sees to make sure the clutch is engaged I guess. You need to check that too. It may be that the clutch is slipping and needs adjustment. If the controller senses this, it will shut the A/C down I think. As well, after a minute of A/C being on, feel the compressor and see if it has gotten really hot.

cliffnuggets, did you solve your AC problem?
I met the same problem, and I have already replaced the drive belt, which doesn't work...

Thanks

Count me in on the same sinking boat, but it doesn't even give me a nice burst of cold anymore... it's just the taunting blinking light. :frown:
