A couple of weeks ago, my tag lights went out. Wasn't the bulbs, so my dad ran a hotwire from a tail light to the tag lights to keep them on. A couple days ago, my AC stopped working. Not blowing any air at all, cold or hot. Lastnight, I got in my car and none of my dash lights are coming on. Any idea what's causing this?

There is not a separate fuse. The tag light is powered off of the tail lights. If you have tail lights but no tag lights your problem is either bad tag light bulbs or the connections between the tail lights and the chassis ground at the tag light bulb sockets.

I would check the socket that the bulb goes in,also,if there is moister getting in the tail light this will also cause the problem.

The only thing that both the brake lights and tail lights use is a ground connection. Keep in mind the warning light on the dash may be for any exterior lamp. You may need to check the sockets and grounds on all four corners of the car.

These are not related issues. The problem is a really common one. Most likely the circuit board is bad. I sell about 4 a week for these trucks. You can pick them up for around $20 at your local parts store.

Check your fuses. I had the same problem with a 90 Honda civic. Dash lights went out, tail lights also went out. Replaced 1 fuse and all came back on.

Any time you get any check light, you should
be at a repair in a couple of days, or at least
check for codes. Still need it diagnosed and
repaired in a week

Otherwise you waste gas,polute the air or could
cause some damage,as you don't know what the issue
is that set the light

The fact the check light went out, doesn't mean
the problem went away.

Don't clear any codes you find,their needed to diagnose
the system faults

If signal lights are working, probably a failing headlight switch. Even though fuses seem OK, you can try replacing the appropriate fuse.

bad ground to dash circuitry....... dont overlook anything ... the powers are suspect also but not as likely ... do it right , dont rewire /hotwire it... it will be easier to find the problem then Frankenstein it.... good luck

I have had the same issue recently. I have a 2002 Gr Cherokee Ltd 4.7L. At first I thought it was the bulb, replaced the bulb to no avail. Then I thought maybe the bulb was rattled loose due to my subwoofer, but that still was not the case. After testing all my fuses I decided to test all of my lights. The hazards worked, back up lights came on, tail and brake lights were all working also but for some reason the blinkers will go out and the right rear brake light will not come on. It always comes back on for me though, so now I just use hand signals when it is temporarily not working. My only suggestion is a problem in the wiring.
