RE the turn signal: If the prop is they are not canceling after a turn, you need to pull off the steering wheel to get at the canceling springs. If you have a Chiltons, etc. the procedure should be covered. You'll need a puller. Take care to remember how the horn parts go back in (make a sketch, take a photo, number them, etc.).
RE the AC: If the compressor will not run, could be lack of refrigerant charge. A '90 would have been R12 OEM. You will need a R134a conversion. The root cause no refrig would be a leak. Parts stores sell leak detection kits. I do not have any experience using them. My '94 cherokee had a leak at the condenser. I replaced it with a new one ($150); did the work. You then need to pull a vacuum on the system to evac air, then charge. If your not familiar, I recommend a reputable radiator / AC service garage. They should have the proper equipment, gauges, etc. I wasted a lot of time an money by charging myself without evac'ing the air; pressures were very high. I was lucky I didn't damage the system.
#1603 of 2589 Screeching sound - AC first turns on
Aug 04, 2005 (8:59 am)
I have a 1996 Jeep Cherokee with 220K miles on it. Recently, I noticed that whenever I would turn the AC on when the engine is cold, a screeching sound would come for a short while (till the engine warm up). I replaced the Serpentine belt and tightened it to specification but the problem still remains. The AC pulley seems to be turning fine (belt is not skipping) while the compressor makes the sound. Could this be the sign of a bad compressor? Is it safe to replace a compressor by yourself - not take it to a garage?
#1604 of 2589 Maintenance Required light on 91 Cherokee
Aug 05, 2005 (7:39 am)
I have a 91 Cherokee. The maintenance required light is on.
It cycles with the key on but comes on and stays on when I engage the starter.
I do not have an owners manual and Chilton says nothing on it. Does any one know:
1. is it some thing like needs oil change?
2. O2 sensor needs check etc!
3. HOW TO RESET IT

You're calling this light a "maintenance required light". Do you also have a "Check Engine" light or a "Service Engine Soon" light? If so, it probably is just an oil change reminder, or something along those lines. How long have you had this Jeep and how many miles are on it?

If this only occurs when the belt is cold then it needs to be a bit tighter. If it continues to occur even when hot then it may be a compressor giving out.

Hey.. not sure if you solved your problem yet.. but I had a totally diff car with exactly the same symptoms. Letting it "cool" actually let the AIR trapped in the corroded FUEL LINE to escape, thus allowing enough fuel to get in and run the engine when starting.
Took many mechanics digging around at useless things before one of them thought to check the fuel pressure. it was 50% of what it should have been, and discovery lead to a corroded fuel line. This was an '86 Cavalier, but that's irrelevant. Just a thought for you if you have been only focuses on electrical stuff.

Aug 06, 2005 (6:17 pm)
What does it mean and what should I do? Car seems to be running ok.

That check engine light could mean anything. If you don't want to use your local Jeep dealership, then take it to AutoZone. They will pull the codes for you for free. This code/codes will point you in the direction of where the problem lies.
That light will come on when the computer notices a faulty signal from one, or more, of the sensors. Chances are the Jeep will run fine for a while. But, if igored long enough, small problems can turn into large ones.

We have had the Jeep 2 weeks.
202000 more or less. No owners manual. How do i reset the "maintenance required light? It is not the check engine light. I have disconected the battery to reset the computer but after normal kight cycle at switich on, lights lite then go off, wheh I engage the starter the light comes back on and stays on.
So how do I turn it off/reset/?
#1611 of 2589 2001 jeep cherokee coolant loss and oil pressure problem
Aug 08, 2005 (10:11 am)
I have a 2001 Jeep Cherokee Classic, with the 4.0L inline 6 and 92,000 miles. I bought the Jeep 2 years ago with 60,000 miles on it. (it had been lady driven and was well pampered). About 6 months ago, during the winter, I noticed the electric cooling fan running often. It was very noticeable to me because I rarely have heard the fan kick on since I had owned it ( I rarely run the A/C, even in the summer). A couple days later the engine started overheating and I checked the coolant level and the reserve tank was empty and the radiator was low. I took it in to the shop, they believed the radiator was ruptured, even though there has never been a drop of antifreeze under the Jeep, so I got a new radiator. The problem persisted. About every week and a half or 2 weeks, I had to add coolant to the reserve tank because it would be almost empty and the engine would try to run past the 210 degree mark. Once again, there has never been a visible leak anywhere. I kept this up for a few months and finally took it back to the shop, where they tore the engine down and found the exhaust manifold for the first 3 cylinders was white and shiny inside where coolant had probably been burning off. The head was slightly warped so they machined it flat and magnafluxed it, and put on a new head gasket. Also they put in a new thermostat and oil pump. I am also having an oil pressure problem, when the engine is hot and at idle speed, the oil pressure will sometimes drop to about 1 or 2, prompting the check gauges light to come on. Checked it with a manual gauge, and it also read about 2-4 psi. Cleaned the oil pan, did a pressurized oil purge, and checked the receiving unit. After all this was done, a week or 2 later, all the problems are back. I have had to add coolant twice because the reserve tank was empty and the oil pressure is dropping to nothing at idle speed. I know it's a long post, but anyone had any similar problems or suggestions?
