anyone ever experiance this problem, my a/c compressor will come on by itself, even when the switch is in the off postion, if i slide the switch to on then back off it will sometimes turn off and sometimes not, but if it does turn off it will come back on again in a few sec. anyone ever have this problem before and if so what caused it, maybe worn switch? thks for any help

 

sorry to bring this BTTT but i seen someone else post a problem like this, tried to search but no luck, any ideas anyone, i would like to turn my a/c off sometimes, thx

 

I just had a similar problem. When I bought my car, the AC blower switch acted funny. I had to wiggle it to work. Then one day I lost all speeds but one. High speed was now on the first(low) position. Additionally, if I had my AC or fan on when I stopped the motor, the fan would just keep blowing.

I was advised to check the high speed fan relay. I pulled it and replaced it eventhough it looked good. Started car, and the problem was still there.

Last week I finally got around to checking if it was the switch. After careful removal of the radio, I discovered that the A terminal on the switch had been totally fried. Replacement returned the functions to proper working order.

If you need me to walk your through the AC blower switch replacement, I can type-up a more detailed description. Just make sure you have a 9/32" socket, a 1/4" box-end wrench, and perhaps some needle-nose pliers. (i'll be referencing a Firebird though.)

Posting this question in Electronics forum would have gathered more replies.

 

thanks jade, i'am thinkin its the heater a/c head unit itself because its actually the compressor itself that runs and i can't turn it off, i slide the switch over to off but no off, i checked some catologs they go about 100'bucks new, i'll check ebay or junk yard next, thanks, didn't know bout electronics board, i'll look there, thanks
