2002 Hyundai Elantra dome lights, clock, and stereo not working. With key on, i get a positive test from yellow wire to stereo but not red and not with no key. All fuses seem fine. Any ideas?

Check fuse 25 in the passenger compartment fuse block. If the fuse is good check for power to the fuse.

I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

Answer 2 described my problem exactly, & solved it
in my 2006 Hyundai Elantra.
I had put the black "fuse puller" looking jumper in backwards.
Reversing it brot my radio, clock, dome lights & remote back to working.
Thank You

Hi, behind your climate control panel is something called the Electronic Timing and Control Module (ETACM). This is like a computer for the chassis. All of the troubles you mention are tied into the ETACM. If you could find a used module at a salvage yard, it may solve your problems at a reasonable cost. To troubleshoot the problem will be very difficult and must be left to the dealer, which could be expensive. Just the same, I have included a few of the wiring diagrams in case you have a good multimeter and would like to try troubleshooting.
