Question about 2002 Jeep Grand Cherokee

1 Answer

2002 Jeep Grand Cherokee limited 4.7 speedometer flips around when headlights are on bad, and rarely when they are not on.

When i'm driving my jeep with the headlights on the speedometer jumps around the headlights kinda flicker, and every now and again the parking brake light and abs light kick on.  Also every once in awhile the speedometer will just fall to zero when my headlights aren't even on and the car makes a ding noise like a warning should show up, but there isn't one.

    Ok so i took the jeep into the dealership they initially thought it was a loose ground as well, but only one ground came up as loose.  So they tightened it up and it turns out that wasn't the problem.  they started testing my pcm and they got zero signal feedback from it... Is this legit or am I just wasting money?

    Speedometer works part-time. Stops working then jumps around and occasionally works correctly

Sounds like a "bad" earth on the dash head unit. Also check enging to chassis earths, gearbox to chassis, battery to chassis etc.

    The PCM should give them a system history report, the "logical" point to start with fault analysis. Umm, dashboard is probably PCB therefore another suspect point could be the edge connector or PCB track(s)

2002 Jeep Grand Cherokee Limited 8L, engine revs while driving, especially on long road trips


THE FIRST THING IS TO HAVE THE COMPUTER SCANNED FOR CODES, THESE CODES WILL HELP IN FINDING PROBLEM, ALSO CHECK THE IDLE AIR CONTROL VALVE, AS THIS VALVE CONTROLS THE IDLE AND GOES BAD OFTEN. AND LAST TAKE A GOOD LOOK AT VACCUM LINES FOR LEAKS, MOVE THEM AROUND AND LISTEN FOR A HISSING NOISE. GOOD LUCK.

Computer light says service 4 wheel drive switch


According to the mechanic who works on my 94 Jeep it's one of three things:
1) Corrosion on the connector to the switch (which is located on top of the transfer case).
2) A bad switch. Part cost about $22.00 or,
3) A bad console display. he says they have had a fair number of console display units fail.

The speedometer on my 2002 Grand Cherokee Jeep stop working?


I believe your speedometer works off of a sensor either in the wheal or transmission, check this first then check your speedometer, sometimes they go bad and you have to replace the entire dash.
