Cruise Control Not Working On Jeep

Jeep Cherokee Cruise Control Has No Power

Cruise Control Fuse Location

Q: Its a 1996 Jeep Grand Cherokee and I cannot find a fuse for the cruise control, and it seems to have no power to it. The light on the dash will not come up when the cruise control is activated. I have looked under the hood and on the passenger side door panel fuse holders, and the cruise control doesn't seem to be indicated in those two areas.


A: You’re not really going to find a fuse for the cruise control on your Jeep. Why? The cruise control unit is controlled by the vehicle computer and receives its power supply from the same computer. If power is not being supplied to the speed control servo you want to inspect the stop light switch. The stop light switch, on your vehicle is really 3 switches in one. One part of the switch is for the stoplights. The other two parts are for the cruise control and, if not operating correctly, the cruise control will not operate. Also be sure to check the vacuum supply to the cruise control unit. It is not uncommon for a vehicle of that age to have cracked vacuum hoses. A cracked vacuum hose will result in a loss of vacuum supply. Too little, or no vacuum supply equals no cruise control. There are a few checks you can make with a voltmeter, but to get down and dirty with the cruise control on your vehicle requires a computer scan tool too.

Troubleshooting Gauges Issues On Jeep

Jeep Cherokee, Gauge Problems 

Q: All gauges: The speedometer, tachometer, and gas gauge on 1996 Jeep Cherokee not working.Tried replacing the instrument cluster pod and still have the same problem. When they went out they would work off and on and the needles bounced around at times, then went out for good. Any suggestions?


A: Start with checking the fuses. The number 7 fuse in the fuse panel is a main player in powering up the instrument cluster in your Jeep. You should also realize that the action of the instrument cluster displays (speedometer, tachometer, gas gauge, etc.) are primarily a result of information processed by a computer called a Body Control Module (BCM). Because so many of your gauges are acting strangely the BCM is suspect. The BCM does have built in diagnostic abilities that can be accessed with a scan-tool. Virtually all of the lights and gauges on your dash can be operated via the scan-tool, through the BCM, for confirming function. Before replacing any more costly instrument clusters or installing a replacement BCM (the cost of a replacement BCM will create respiratory problems), be sure to check the fuses and electrical connectors. Proper diagnosis will save you money.
