#218 of 354 1999 Buick Regal GSE electrical issues
Jun 04, 2009 (7:52 am)
I have found many people on here that are having issues with the electrical system. My issues started with the dash lights going out. Then the ABS light came on, then the traction control light, and soon after the service engine soon light.
At that point we parked the car and have been trying to tackle the issues for the past year. The issue grew into a more serious situation when the turn signal started to kill the engine.
Then we started to hear a loud electrical growl from under the dash. The noise was coming from a white control box/circuit board mounted to the drivers side foot well. Not sure what it does, but may need to replace. Along with the noise, the dash goes haywire, flipping from imperial to metric units and gauges going back and fourth.
From what I have read on here the problem may be the Ignition switch. One more question I have is about a chip mounted under the dash, does anyone else have this. It looks like a non-factory modification. The chip is spliced into the main wire harness. A thick yellow wire and some others. What may this be?
I need to sell the car for $$ on another project, but would like to address as many issues as I can before selling. I also can't seam to keep air in the tires due to the chrome plating flaking off of the rims and not allowing the tire to seal.
GREAT CAR, but some issues after 100k miles (I have 186k)

Is it not funny 1 part causes all that trouble...IT is the turn signal switch......
I have seen damage to the ignition too but you seem to be diagnoising the turn signal switch issue....If you want I can give you step by step instructions...Get the old one out of a junk yard and bam for 25$ you will be fixed

Any idea where you can get these resistors? I have the same problem. I removed cluster and the resistors are overheated and coming loose from the board.
#221 of 354 Radiator cooling fans sensor?

I just got this 1996 regal 6 cylinder. When you idle the fans wont turn on. I bypassed the control switches and can get them on. My question is, is the coolant level sensor the same as the heat sensor that tells the control units to send power to the fans?

#224 of 354 1990 buick regal, dies while driving
Jul 03, 2009 (8:26 pm)
I have recently aquired a 1990 buick regal 6 cyl with electric seats and windows. I don't know what if anything has ever been done to this car. There were a few times I would take off and before I got 2/10ths of a mile and slowed down for the stop light the car died, the electrical completely shut down, but the engine still accelerated and in a few seconds all the electrical would be back to normal. sometimes I was low on gas but one time I had almost a full tank. My son borrowed it and was driving home when the the car just died going down the freeway, He was out of gas. But the car refused to turn over or make any sound at all for about an hour, then it would turn over. (but of course he was out of gas so it wouldn't run for long very well.) Is it common for this car to do something like this. Is there a connection between low gas and the electrical where the electrical will reset itself after a time?
#225 of 354 2000 regal, Instermint cluster odometer not lighting up, why

When the engine temperature meter don't work the car don't start and if started the gearbox is jammed on #3. If the temperature meter works, everything is OK. The temp sensor is changed, but it didn't change the problem. Where's the problem?
#227 of 354 Fuel gage not working right
Aug 04, 2009 (7:06 pm)
when the key is in the run position, it shows how much gas i have, when the car is moving it goes to full tank, is this a ground to sending unit problem or whole sending unit or something else?
