If there are any Ford Techs here or someone with access to wiring diagrams on Chilton On Demand or whatever the new flavor is these days. I could use a little help.
My 2007 Ford Ranger 4.0 is giving me a headache with the A/C. Trying to chase down what is going on. Long story short I had to replace the compressor and along with that I changed the orifice tube and receiver drier. Had the system charged, held a vacuum and worked well for about a week. Clutch wont turn on. I jumped the pressure switches, checked the relay, checked for voltage at the clutch and all good. The odd thing was with the key on, engine off the voltage at the clutch is about 7v. Engine on I am getting 14v.
When I jump the switches the idle speed increase but the clutch won't turn on. Clutch is new with the compressor. Air gap is within spec (.020") on the clutch. I swapped the relay with a known good relay from another location in the fuse block/box. I think there could a ground issue, or maybe it's an issue with the PCM not turning on the ground? It's pissing me off. Especially since I used to be a tech (Toyota and ASE master).
I found an older model wiring diagram but wire colors are not the same and also I am not sure if the system is the same. Trying to find a diagram to help me chase down all of the electrical first. Any help would be appreciated. Also if there are any specific Ranger known issues like this I would appreciate the heads up. Next will be this damn small EVAP leak/code...
