    Problems after trying to fix alternator whine

    OK, so I have had alternator whine for a few months after installing my CD43 and today I decided to tackle it. After trying multiple methods I thought I had figured it out and put it all back together. Later, I needed to go to the store an notice that when I put my foot on the brake, the Check panel light for the brake did not go out. It went out earlier in the day. Also when pushing the brake, the left flasher light illuminates a small amount and seizes the action, but the right flasher works fine. Soon after this, all of the interior lights go out. No fuses seem to be blown, headlights and brake lights work and the instrument cluster works.

    I am sure that I am missing something. Moral of the story is that I still have alternator whine now no interior lights and my brake and turn signals are doing something funky.

    Any insight on this is welcome. I am going to try the turn signal relay tomorrow but I am sure it's something else. Thanks for looking.

    OK UPDATE!

    I fiddled with the turn signal relay and no longer have any issues with the check panel or the turn signals.

    I do however still have no lights in the dash. I have checked all of the fuses and they seem to be fine. I have read that fuse 23 could be the culprit I just don't know. Is there a relay for the dash lights that could be causing the problem?

    Any help would be great.

      I know this is stupid, but I've fallen for this before. Is you dimmer accidentally turned all the way down?

        lol, I wish that was the case. The lights go out when I turn on the headlights.

        The cluster lights only to the instruments, the rear defroster and hazard switches and the OBC lights are whats in question. I am not sure about the cigarette lighter or ashtray lights but I couldn't even tell you if those worked to begin with.

        I am so confused as to what it was because the were all working the night before I started this crap.
