All,
I've been lurking here for a little while now, and am glad to say I went out last week and finally bought an XJ. It wasn't by any means perfect, but I kinda expected that from a 19 year old car, and really bought it as a project car to learn on (admittedly, I don't know much about cars - I'm along time IT guy with little mechanical experience.) With the help of this forum I've located and fixed quite a few things:
Interior Lights (Fuse)
Blower (Fuse)
Oil Pressure Guage Peaked to Right (new oil-pressure sensor)
Replaced Headlights
Changed Oil
Changed front and rear differential fluid
That being said, I still have a few problems I could use some help with. First and foremost is no-heat (tad of an issue in Illinois winter.) I've searched and read all the no-heat threads several times and just have a couple of questions.
The no heat may be related to a vacuum problem. First, the vacuum hose coming from the blower area to the heater control valve (pinkish tube) was not connected to anything. I reconnected it (sorta rigged because I can't seem to find that small of vaccum line anywhere.) This didn't seem to help. The heater control valve is rusted to high hell, so I bought a new one of those and plan to install it tonight.
There's another vacuum problem I discovered when I went to replace to the left front headlight. The vaccuum reservoir right behind the bumper had two big holes in it. I took this into the auto-parts store but it must be pretty rare because no one seems to carry it. Probably going to have to be a junk-yard replacement. I patched the holes with JB weld and put it back in, but I'm not sure if this was really tight enough to keep a vaccum. This may be the cause of my heat problems; maybe more. Is there anyway to bypass this temporarily?
Based on prior posts involving no heat, it sounds like the next step is to burp the system and then flush the heater core. Question here is, do I need to drain the coolant before flushing the heater core? How about before replacing the heater control valve? Also in the Haynes manual it says to have the A/C evacuated before you start messing with the heater core. Is this absolutely neccessary?
Other than that, I've got a few minor problems. Oil leaks, but it's slow and I haven't traced it back yet. Same with coolant, but pretty sure I know where the coolant is leaking.
This all is on a 1990 Jeep Wagoneer Limited (Woody!). IL6 Rendix MPI.
Added bonus: One of the previous owners added a "Y" to the "PART TIME" light so when I throw it in PART TIME it says "PARTY TIME"
Thanks for your help in advance.
