Car Forum / Ford / Ford Explorer / October 2004AC pump problem
97 EXPLORER XLT My ac compressor keeps clicking on and off. any reason why. Thanks in advance for the help Searcher 1 Yeah, cuz that's how it was designed to work ..! > 97 EXPLORER XLT > [quoted text clipped - 3 lines] > > Searcher 1 How often does it cycle? It is designed to cycle a certain amount but if it is cycling rapidly it could signify a low charge or other concerns. As always, AC work is best left to those with the correct tools and knowledge of the systems involved.

It sometimes cycles every couple of seconds and the idle drops almost to the point of stalling. I have no signs as per gauges or lights. A/C works great, heat works great and other than the cycling I have no problems with the vehicle. I have no plans to work on this item myself although I can do anything else with the vehicle I have never had instruction on heating and cooling. Searcher 1 > How often does it cycle?

Left unattended to, this concern could lead to early clutch failure and possible compressor damage. If you're not going to have the concern addressed in the very near future, I would suggest disconnecting the two wire connector at the AC clutch to keep from making the job more expensive at a later date. > OK, sorry I didn't clarify.

I will have it looked at next week, I just didn't want to go in blind.
