    I took my instrument cluster out of the car, took the white back off and then plugged it back in (but did not reinstall cluster). I touched all of the connections and noticed that the DIC came on. I narrowed it down to a few just below the DIC connections. I removed the instrument cluster and took it inside and soldered the bad connection. Reinstalled cluster and it works fine.
    You really could not tell that the one connection had a 'cold' solder.

2005 buick lacrosse cxl... dash lights and interior lights are going dim to bring to dim to bright very rapidly

First, check that the battery connections are clean and not corroded. If not look for the ground wires that connect to the chassis. Check to see if any are corroded or loose. Finally if that has no effect, you have a short somewhere in your wiring. The easy way to isolate it is to pull the fuses for each device one by one and see if the dimming stops. The last one to cause the dimming is the problem. If it happens when you hit a bump it also might be a ground fault in the interior car grounds....good luck!

2009 lacrosse...compass, clock and milage lights sometimes stay real dim and then later pop up to normal brightness so I can read them...what goes ?

Starting car in garage turns on headlights which makes believe it is dark out and therefore dims dash lights. When car is out of garage it switches to running lights which allow dash lights to get brighter. I guess I should have figured that !!!
