I have a 1999 regal LS. The engine would stop at random times in traffic but restart and run again. I had the car in the shop for weeks before the problem was found. I do not know the exact parts replaced but the electrical problem was in the area of the ignition switch. The car has run great for years. Louisville, KY. 40220
If the outside temperature gauge is not reading the right temperature on a Buick Regal, perhaps it has become damaged. It can also not read the right temperature if it is wet or covered with dirt or snow.
right above the neck
Hazard light on the 1991 Buick Regal is on the right side of the steering column. It is an unassuming black rectangle which slides up to activate.
Drop the fuel tank, then it's right there.
should be on the passenger side right along the fire wall
Look at the rear of engine right side
Probably under the glove box or on the inside right firewall.
I had the same problem check the crank shaft position sensor i payed maybe 25 bucks for one and its not all that hard to change with the right tools.
GOTTA GO FROM THE BOTTOM RIGHT BY THE TRANS RIGHT ON THE FLY WHEEL 2 BOLTS VERY SIMPLE.
Its located on the passenger side of the dash right next to the door.
Under your hood there should be a diagram. a sticker on top of the radiator...in that area. If not you could probubly google "Belt diagram for 1998 buick regal" image search. make sure you get the right diagram for you motor.
