Got. 02 ford ranger 4.0. Ac compressor clicks on and off quite a bit. Even with the heat on. Any suggestions?

 

May need a ReCharge

AC is used all the time to DRY THE AIR in the cab, OFF and Pane/Floor should have compressor off, any other selections it will be on

 

First off I wanted to say thank you Ron for taking the time to help me out. Well the coolant leak was the water pump and a lil gasket. About the compressor the only setting it don’t click on the single floor setting. 2 days ago the whole unit was sweating bad. Is it a sensor or relay that has to be replaced?

 

You need to get a set of gauges on the system. As Ron suggested, it may simply be low enough on freon that the low side pressure switch keeps shutting the system down (as it's designed to do). If that's the case, you'd need to locate/repair the cause of the low pressure, then charge accordingly.

 

+1 ^^^

"Sweating bad" means your weather at this time is humid, so AC is doing its job, condensing moisture out of the air, inside the cab and outside the cab

Yes, there are 2 sensors, they are Pressure Switches on the AC lines in the engine bay
High Pressure switch prevents AC lines from exploding if system gets blocked
Low Pressure switch prevents Compressor from burning up if system fluid gets too low


When compressor clicks off and on it could mean Fluid is low so as its compressed system runs out of fluid and has to wait for more fluid to come thru back to the compressor

As CalebJ said, best to hook up some pressure gauges FIRST then decide where to go from there

 

that was very helpful. Thank you for your time. I have someone with gauges tomorrow to test it. Thank you once again. This site is the best.
