Does my 1998 Grand Cherokee Limited 4.0L speedometer have to work in order for my cruise control to work. is there a way that i can bypass it to work

1st question, yes the spedometer has to work for the cruise to work or it has to at least get a signal from the speed sensor, if the problem is just the speedometer head then the cruise will still work, as a matter of fact that is how we test the system if when one of these come in the shop with an in-op speedometer we take them out and try the cruse if the cruse workes then we know the problem is just the speedometer head, if the cruse does not worn then it is a problem with the speed sensor or the control circuits for the speed sensor.

2nd question there is no way to bypass the the system to mke the cruise work yo dont have a speed sensor signal so the cruise has nothing to use a refrance in a way it thinks the car is not moving.

good luck, try replace the speed sensor in the transmission it might fix both problems.

Two possibilities, the speed sensor on the transmission or the stepper motor that drives the speedometer in the cluster. Is your cruise control working? If it is, then the problem is with the cluster.

Speedometer works intermittently

It is most likely the speed sensor in the transmission.

Speedometer needle bounces

Easy one. You need a new speedometer cable. The cable inside the outer sheath is sticking and binding. Don't bother lubing it on a '86, that'll only help a month or so. You may also need a new nylon drive gear inside the transmission housing (needle nose pliers will pull it out when you remove the speedometer drive cable from the tranny.) You may be looking at $40. Probably less. You'll get to stand on your head to disconnect and reconnect it to the dash. Buy one of those LED "headlights" for working on the dash. Your knuckles, arms and hand skin will appreachiate it! And you won't have to try to hold a flashlight in your mouth while working!
It's very unlikely that the "clock spring" inside the speedometer is bad these days. It did happen in the 60's, but I haven't seen one since.

Fuses blown do not have manual to help locate fuses

The fuse panel should be below the steering wheel to the left. A blown fuse would explain why the electronic speedometer isn't working, but a blown fuse wouldn't explain the OD light. If the speedometer starts to work after replacing the fuse, but reads erratically, you might want to check the vehicle speed sensor.

Transmission speedometer problem

This all can be caused by a defective Vehicle Speed sensor, also called a VSS, also run a test on the computer to see if any codes are in memory that will help to sort this problem out.
