I have an 03 model and for a while the A/C light would blink on and off thus shutting off the air. This has been going on for a while and then this week when I turned the air on the light is on but the compressor clutch is not engaging. Could this be caused by the A/C control switch. I checked the fuses for the A/C and they are ok. I changed out the relay and this didn't help either. I need some advice on what I may do fix it . It is hot and I don't have much money. I am going to try to take the switch apart and clean it this weekend. Thanks for any help you can give.it.
