How do I access dash lights on '98 Grand Cherokee?

no comma's used. wow.
ok,
dash board goes dead, everything , radio too?
head lights go dead.
or just the cluster dies. or just cluster back lights in PARK mode.
car runs ok.?

the cluster (if only its bad) has 2 fuses, replace those.
if that dont fix it ,scan the pcm ,
using any scan tool ever sold.

codes p0456 and p0442

The fuse panel is found on the passenger side of the vehicle. Open the passenger side door and you should see a "fuse access door" on the side of the instrument panel/dash just under the vent.

spray the slider that controls it with electrical contact cleaner and move it all the way up and down a couple of times. mine did the same and resolved it that way 3 months ago.

Good Evening, right behind your belts is your water pump. This is something you shoudl have replaced pretty darn soon if not it could be detrimental to the life of your engine. Hope this sheds some light on your situation.

its caused by moisture damage my friends dad has the same exact problem

Hi, you have to remove the ash tray and the panel around the radio then you will be able to remove the aircon control panel.

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.
