I just picked up this 92 MJ 4.0 5spd SB 2wd from a meth head hillbilly a week ago. Of course he lied extensively about what had been fixed. Thankfully I didn't pay much, and there's no rust on it!
I'm a retired auto tech, but totally new to MJ's. I have 3 wranglers in the driveway, and I got the MJ to become my daily driver!
Brakes are the important issue to deal with first. So here we go...
While driving I randomly start to feel resistance against the drivetrain, then can smell the hot brakes. It's evenly across the front brakes, no rear interaction that I can tell. Let it cool, and can drive on for a few miles, or hours, it's random.
The previous owner apparently had an issue as well because upon inspection it has a shiney new set of rotors, pads, calipers, hoses, and master cylinder. I removed the calipers to check them, and they collapsed easily, pushed fluid back to the master cylinder resivoir with no issue. Fluid is all clean & clear, though I bled the system anyway, and filled with fresh fluid.
Any ideas?
My mode door in the HVAC air box is stuck on defrost. I'm fairly sure it's going to be the vacuum actuator, as the vacuum lines aren't showing any leaks. I'm not sure where the mode actuator is located. I always like to test the part before I just think I have it narrowed down. I've seen stuff get down in an air box and jam up the doors. Techs have cost customers big $$$ only to find a $.25 Bic pen holding a blend, or mode door from moving!
I've searched online, but I get mixed results.
If someone could point me to the mode door actuator.....
