Question about 1996 Jeep Grand Cherokee
1996 JGCL with 175K miles has some problems and is overall a good vehicle BUT I keep getting taken by repair places that do not fix it!
Problem 1: Oil gauge, oil light, chime activate for low oil pressure at idle after 15-30 minutes of driving/use. Had oil sending unit changed twice and still have problem. Oil gauge goes to zero during idle but no rough idle or noticeable change in engine (318ci V8) - can't submit for emissions testing with indicator light coming on.
Problem 2: Automatic door that controls air flow seems to have a problem (getting stuck) as get hot air flow intermittently. Change out of temperature controller module did NOT cure problem. Problem started AFTER after dash tear down to replace A/C evaporator core (known defect with these vehicles).
I greatly appreciate any help, insight or just plain straight advice on how to find a superior Jeep mechanic.
Problem#1 - first check idle air mixture - even 150 RPM too low will cause PCM to think it's not getting enough pressure. Also I checked with my ASE certified mechanic and rings, crank bearings etc could be worn to the point that the pressure is actually getting too low. The heater box in problem #2 is probably the culprit. Many inexperienced techs will put these together incorrectly so it will need to be reassembled correctly for it to work properly. Good Luck - Hope this helps!!!
