Iv done a lot of reading and researching on my problems and found a lot of people find the TCU is the culprit. I went to the junkyard got one and still nothing is working....

The list of problems:
!. Dash board lights
2. HVAC lights
3. Parking/Tail lights
4. Mirror control
5. Cd player
6. Cig lighter

Maybe this will help but when I installed a cigarette lighter it worked for a few days and than all of a sudden stopped. That's when I noticed all my symptoms and problems.

Things iv done:
Relaced TCU
Replaced various relays
Checked all Fuses

If anyone has any other input, I heard maybe the steering stalk. You guys would know exactly what relay those things run off of or maybe wires under dash or rear section I should look for. Thanks!!
