I have a 1990 si, all stock. The ac works well until it is really hot outside. the compressor cycles like it should but every now and then a red light next to the ac switch on the dash comes on. THe only way to get the ac to work again is to cycle the ac switch. The system then begins to work properly until the red light comes on again. I have not been able to find any info on this light. Does any have any insight?

Does anyone have a good schematic for the ac system that shows this light?

THanks

 

bump, anyone?
