My 94 Chevy K 1500 air conditioning compressor Cycles on and off even after I put a can of freon in there it'll be fine for an hour then start cycling on and off again plus the blower fan only works on high if that has anything to do with it

SOURCE: blower for air conditioning fan

some cars ARE DISING LIKE THAT TO DRY THE MOISTURE IN THE A/C SYSTEM CHECK AFTER 15 MINUTES IF STILL RUNING THEN THERE IS A PROBLEM

SOURCE: AIR CONDITIONING

heater controls could be gone

SOURCE: 2000 silverado 2500,my a/c compressor cycles constantly

I had the same problem on my 95. Do you hear it clicking on then off all the time. Well thats what I had. I unpluged the plug at the top of the compressor for about 6 months, got sick of hearing it. I had my system recharged and the problem stoped. I no thats not alot of help, but thats what happend to me. Good luck

SOURCE: air condition fan only works on high speed, no low speed

You have a bad blower motor resistor. This is located under the dash close to the blower motor itself

SOURCE: Heat/AC Blower fan speed only works on High

hello, this sounds like a bad blower motor resistor!! its cheap and easy to change..if you need more info on locations let me know,, good luck.....marty
