    CornFlake-

    I haven't been following the posts about the non-working items but in this situation here I would have to take a methodical approach to it. Do you have a manual / have access to a wiring diagram? What I would do it grab the wiring diagram, get the cluster out and take to the wiring plugs with a meter.

    Try to see if you can peg just where the problem is. If you test the plugs you could determine if you are actually getting power to the gauge when you are supposed to. At the very least it would give you a starting point as to whether the problem is in the gauge of if there's really just no power coming to it when you turn on the lights.

    Just my $.02

    Good luck with it all. I'm sure you'll get lots of helpful tips soon!

    I know this may sound like an obvious question, but did you check all your fuses and relays? Sometimes the aftermarket lights will blow a fuse here or there...

    I would definitley start with Springthing's suggestion with the meter, or even just a test light. If you've got an LS or LT, when you take the cluster bezel off, there should be one big harness at the very top of the cluster, you can check that too.

    Good luck!

    ok so I got an OBD-II tester and it reads, P0650 indicator lamp (MIL) control circuit malfunction.. I don't have time at the moment so I'll get back with you all about it.

    your suggestions are deeply appreciated,
    Dave

    the dimmer wheel controls nothing except to turn on the dome lights when wheeled up all the way...
