1993 Pontiac Grand Am dash light dimmer switch burned out
All lights no car work fine, but the dash is dark except all the warning lights work and the "shift now" light comes on normally as does the high beam indicator. The problem is that the dash dimmer thumb wheel switch and on/off thumb switch on the dash is burned out. GM no longer makes this part. Other than a junk yard, any ideas where I could get (hopefully a new) replacement switch?

check that dimmer is turned up ---and check connections around where radio work was done for damaged disconnected line connector also check dash fuses not just fuses from radio --or your radio may not be compatible to your dimmer circuit -most oem radios display are Incorporated with dash functions and after market ones are not
Your shifter is a column shifter, not a floor shifter, right? Is the headlight switch mounted on the steering column? If so, then this "combination switch" may be the problem. If not, start looking for loose wires, especially ground wires, around the steering column area and the headlight switch area. It would also be a good idea to get access to a wire diagram from a factory repair manual and find out if GM had any Technical Service Bulletins addressing this problem. If I get a chance, I will ask around and see if any of my co-workers ever heard of this problem.
Are your "Park" lamps working on the outside of the car? If not, then you probably have a problem with your headlamp switch. If the park lamps are working, then the problem is most likely with the dash light dimmer switch.
its easier to test them all get a test light turn your ignition to on position turn park lights on and dimmer switch to fully lit position now test each side of every fuse until you find one that only lights the test light on one side replace it. in case you have never done this before its easy the fuses have an open at both top corners stick test light tip in it and the other side to a ground.clean metal surface .

If your dome light is on whether you are go 75mph or not you my want to check your dash light dimmer switch to make sure it is not the cause of the dome light. If not Check you door switches to ensure they are working next check your door latches to make sure they are engaging properly the Bell is possibly a warning of possible passenger loss due to door insecurity
this sounds so simple you may laugh or not most cars have a dimmer switch that believe it or not get turned down by accident by kids messing or when your cleaning your car get turned down while doing the dash as this is the only thing between your fuse box and the light display i presume all your side lights are working yates210456
