Question about 2001 Jeep Cherokee
I had 1 tail light out. Now all my lights are out in the rear. Checked the fuse and it seems to be good. How do I trouble shoot this?
If your fuse 'seems' to be good, it sounds like you don't own any kind of meter.
Your can buy a serviceable digital multimeter that will be useful for many things around home and on your car for <$20 US.
If you have a Harbor Freight tool store in your area, they have usable meters for (on sale) $3.00.
Radio Shack runs higher but still under the mentioned limit.
Fuses can have minute cracks that may not be visible; you can be sure the fuse is blown if it failed catastrophically but otherwise, a meter will confirm that it is good or bad.
Also, the fuse contacts and the socket can fail due to corrosion so pulling and plugging a few times is advisable.
The presence or lack of voltage can be determined with a meter by removing the bulb and measuring between shell and the base contacts.
The bulbs can also be then verified.
I think you have probably lost a bulb but the entire loss of light could well be due to a chassis ground failure that may be dependent on a push-on or bolted/screwed point where one or more wires are attached to ground.
The meter I recommend would be very helpful in se3arching for your problem.
