My stop working when I was messing around with the aftermarket headunit. It doesn't work ant more. I change out the dimmer switch and that didn't work. My question is there a relay or a fuse for this switch? Maybe it's went bad. Thanks

Timer control unit and/or a fuse.

Where is the timer control unit located?

under the dash on the driver's side. It was a pita when I did mine.

maybe the factory stereo illumination wire was used on the new deck?
which usually isnt used on aftermarket decks i think

I use a used a wiring harness for my aftermarket radio. I think the timing control unit is bad.

Help still have the problem. Dimmer won't adjust to either brighter or darker interior lighting.

It has to do with the grounds you either used or didn't use for the headunit. I had the same problem about 12 years ago and I can't remember what the exact fix was, but it was with the grounds back there.

It's definitely has to do with the headunit upgrade that's when it all started. Please try to remember lol. The interior lights are on but they are dark and I just can't adjust it to brighter. As for the ground wires in the back of the headunit I grab all ground wire and tape it together with one added which is grounded to chassis.

I'm going to the junk yard today to pick up a time control unit. This is part of the dimmer
