Question about 2001 Hyundai Elantra

1 Answer

A 2003 Hyundai Elantra electrical problem. All dome lights and the radio and clock stopped working. When I turn on the headlights the dash lights work ok but when I lock the power door they go out and the clock lights up momentarily. If I turn the headlights off then on they work ok. If I put the ignition switch just in the acc position it does the flash the clock then off. I tried replacing the spare fuse for the dome lights and it blew right back out.

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.
