I recenlty noticed my AC clutch clicking on and off rather fast. It clicks every 15 seconds. My AC runs cool, not cold. Is it my switch or is the level of my R12 low? I've never charged my AC system and I've never had a problem with my AC till now.

I ran a jumper on my low pressure switch and the rapid on/off stopped and the AC clutch stayed on the entire time the jumper wire was in.

My question is what is the probem? The switch? Or low coolant?

How do you change the switch? When you swap out the low psi switch, will it let out all the R12?

I did search with little results.

thanks for the help

 

Sounds like you are just low on freon, and the switch is working properly. Don't run it when it is low on freon with the jumper or it could cause damage to your compressor. Better to get it recharged then swap it all out. If you are running R12, I hope you have a license to get it, that and its about 50 bucks a can.

 

yea its just low.mine was doing that,added 1pd of r12 and she quit clicking,blows @ 34 degrees. cost me 65$ with labor

 

I agree it sounds like you are low on freon. Most shops still carry it so you can get it recharged with little to no hassle.

 

Can you post a pix of this jumper? I've always heard of it but never seen it and I'm curious to see it. Sorry, my imagination isn't that good that I can read it and envision it.
