Replying to: ancobaca (Apr 03, 2009 8:48 am) I have a very similar problem right now in my 1998 Cherokee.   In my case, it involves the fan continuing to run after I've parked and shut off the engine. I have to pop the hood, walk around and literally smack the plastic fuse box under the hood.   The culprit in my case is the same type of relay you mentioned. I'm staring at one right now, numbered 56006709 50732. Sometimes relays fail open, sometimes they fail closed. In this case, my fan relay sticks closed sometimes.   Time to replace it with a new relay. I'm not sure how difficult that will be, to find an identical part, but will be calling around to local auto parts stores.

For a couple of weeks my check engine light would come on then go off. Two days ago all my instrument panel gauges including the speedometer began jumping around and falling to zero. It did this several times then turned to normal. My turn signals would not work and my headlights were dim. I parked it and the engine began cutting out. I shut it down and it would not start. Apparent low battery. I took battery home and charged it. After installing battery I drove it home. All was normal except the voltage meter was low and Check Engine light was on. I removed the alternator and had it tested. It checked normal. Battery seems OK. What should I check now? Please all the ideas I can get.

Replying to: curiousjones (Sep 26, 2009 6:04 pm) Did you ever find out what was causing your electrical problems? I have a 2005 Jeep Grand Cherokee Laredo which is doing something similar. The check engine light goes on and off. Sometimes all of the gauges stop working after I hear a series of noises. But the worst part is that the lights go out. If I stop the car, and turn off the engine and then restart it, the lights usually come back on. Tonight they wouldn't come back on. I found out that if I pulled the dimmer/high light control toward the steering wheel and held it there, the lights stayed on dimly. I turned on the flashers and drove carefully home. I have had it in the shop three times and they say that they need this to be going on to run their diagnostics. Unfortunately, so far, it has only happened on weekends and evenings when they are not in the shop. I am getting desperate. I need my vehicle but I am afraid to drive it at night. Any suggestions?

Replying to: petunia4 (Nov 28, 2009 5:25 pm) My problem ended up being the battery after all. Since I had the alternator checked and found it OK I decided to pull the battery and have it checked. It turned out being very weak. The low voltage must have disabled the alternator from working correctly. Don't know for sure what to tell you about your problem. Definitely sounds electrical somewhere.
