How do you change headlights on a 98 cherokee?

check drl unit if not found integrated in fusebox check connections at battery and all fuses if ok if no test light is available take each fuse out 1 at a time and check if not burnt then you have relays for headlights and parking try the 4 way hazards to see if the parking lights function then if all is good play with the multifunction switch to see if not burnt

99 models changed and are not compatable with 98 models.

Chances are if your headlights work and brakelights work just no tail lights its probably your light switch

that wont be a fuse. yud have to blow 2 fuses for that to happen. (high and low fuse)

i would look more closely at the ground and power to the circuit, especially if they were both operating properly before.

Just need take off the screws; for details check the graphics and ilustrations in the Jeep ZJ Grand Cherokee Service Manual

Hope helps (remember rated this) Good luck..

You have two screws at the top of the trim cover. remove them and tilt top towards you and remove from slots at bottom.
There are four screws holding the ring around the lamp. spray them with solvent and remove them the rest is just unplug and plug back in don't put it back upside down. (use a really good new screwdriver and if screws on ring won't come out after soaking tap the back of the screwdriver with a hammer to break rust in threads)

look in between the marker and headlights its a screw there screw it out
