sounds like a bad clockspring 1998 BUICK REGAL 3 8L V6 Supercharged Air Bag Clockspring RockAuto

You mean the lights for the gauges come on and off with the headlight switch off ?
Does this happen even with the fuse removed ?

if your fuse is good. and you have power at the brake light switch and when you hit the brakes you have power coming out the otherside of brake light switch/which would be the white wire/ check that the white wire is sending power up the turn signal switch. if theres power there and your turnsignals work? im afraid that your turnsignal switch is bad rare but it has been known to happen.

Spray the latch with a good penetrating oil, then pop the latch back into the proper position with a small screwdriver. Sounds like it's just a lack of lubrication, which will happen over time.

you can go to autozone they do a free check and can tell you what it is

This sounds like one of your door jamb switches have stopped working.

This could also be the dimmer switch on the dash. If it has failed, it could keep the lights on.

Also make sure you don't have the dimmer switch turned all the way up to where it keeps the lights on all the time.

First things to check would be fuse(s) at dash & under hood, as well as rad fan relay & possibly coolant temperature sensor.

The flap that directs the flow of air in your dash is stuck.

the dinging is from having the turn signal on to long it s a warning I know that sounds strange, mine did the same thing happen to me i made a turn but the turn signal didnt shut off couple mins. later i hear ding ding ding looked at dash turn signal was on shut it off it quit dinging. hope this helps
