- If it ain't broke, break it so you have to fix it.
I have a 1997 Mazda B-4000 SE 4.0L Xtr Cab 2WD only 96k Miles (same as a Ranger XLT 4.0L). Last couple of years I've had the AC slowly lose Refrigerant to the point I was only getting Cool Air, not Cold. I refilled it with "Johnsen's" brand 134a and had nice cold airflow again all summer, fall and some of our "Hot" winter days here in So Cal. Suddenly today the AC failed - when switching on normal AC I could hear squeaking noises, no cool or cold air and then I could smell some "burning" odor, I quickly turned AC off. When I got home I popped the hood, and briefly turned on AC again. I saw that the electromagnetic clutch wasn't turning at all, then would turn for a couple seconds intermittently but mostly not run. There was a bit of smoke from the clutch and a "somethings seized" type of sound. I turn all off.
I've done a lot of engine work, nothing in the AC area, so I have no idea how to diagnose this failure. Is it the electromagnetic clutch or the compressor (like seized)?
Parts are getting hard to find for Rangers / B-4000's, like I couldn't anyone selling or making AC hose assemblies anywhere. What's the situation for Clutch and Compressors for a 1997 vintage Ranger/Mazda 4.0L AC?
How difficult is the swap out of the clutch and/or AC compressor for someone with good experience with engine work?
Thanks guys,
