DIY Auto: Intermittant A/C. Compressor clutch diagnosis on a 1990 Jeep Cherokee.
This apparently is a common problem with these A/C compressors. Symptoms are A/C works when things are cold. When things warm up, the clutch fails to engage. I've had this jeep for most of its life and this has always been a problem. In the early stages, turning the engine off/on would get it to work. Then moving the dash control to vent and back would get things going. Now, a mallet to the compressor housing engages the clutch but only briefly. Not a solution but proof of where the problem lies.
I by no means am a professional mechanic but I thought by making this video it would assist other non-professionals help diagnose their intermittent A/C cooling problem.

As I said in the video you need to be responsible when dealing with refrigerant, also in some locations it's not legal for you to perform your own AC work so keep that in mind and observe your local laws.

The AC compressor clutch is an electromagnetic device that engages the air conditioning compressor. This unit is composed of three parts, the clutch plate, the hub and the coil. The clutch coil is the one that creates an electromagnetic field around it, which attracts the plate and engages the clutch. The plate is also linked to the drive or serpentine belt and is driven by the crankshaft. The hub and the plate have to be calibrated to a specific gap using a feeler gauge.
The purpose of this video is to illustrate how almost all AC compressor clutches are wires. The actual wiring may contain other components, such as transistors and IC computer chips, but the control itself is the same. In all cases, these extra components are used to control the relay coil, which in itself controls the AC compressor clutch. This simple circuit can also be used to wire an older vehicle due to lack of parts and high costs.
Here is how this circuit works.
This circuit has one relay, a refrigerant pressure switch, and a micro switch. The micro switch is a W O T or wide open throttle switch used to disengage the compressor clutch during wide open throttle conditions. This is done to protect the compressor from damage at high engine speeds.
Electrical current flows from the 12 volt power feed to the fuse. Then current flows to terminal... Get the whole story right here in this video...Enjoy...

Serpentine belt noise - A/C compressor clutch broken
2007 Grand Caravan with a serpentine belt squeak and rattle that turned out to be a faulty air conditioning pump. Some extra basics on a car jack, impact wrench and torque wrench. I incorrectly use "pressure" instead of "torque" fyi.
