Default A/C Compressor Problems...

This started only a couple of days ago, but when I run my compressor for the A/C, I can hear it clicking on and off. I checked the wires and fuses, and they seem to be fine. So why is it cycling on and off every couple of seconds? It is driving me nuts because with the compressor not on all the time, it can't cool the car very well.

Low charge can be one culprit

Default Re: A/C Compressor Problems...

it cycles on and off because it's probably low on freon, that's a safety feature to keep from burning up your compressor. Not enough pressure in system triggers the clutch off, then your demand for A/C triggers clutch on,then low pressure triggers clutch off, then your A/C demand triggers clutch on, then low pressure......get it?

Sounds like the solution to me, and considering it hasn't been cooling like it should anyways...

Default Take a peek at the sight glass on the top of the receiver dryer

You'll see the bubbles flowing by as the compressor kicks on. If the system were full, you'd have no bubbles, just liquid freon flowing past.

Since you'll be recharging it, adding flouresching dye and checking for leaks, I'd recommend spending $25 on a new receiver dryer. She'll cool a ton better with a new one and it only takes 10min to R&R.

It can also be the expansion valve

Default There are 3ea relays in line for the AC. Hope that one of these isn't the prob>>>

Hope that your prob is low freon. I'd start there like 4corners and gmbcheif said...
