Question about 1994 Buick Regal Gran Sport

1 Answer

Blown main 40 amp fuse, loss of power, gauges & power windows

I have a problem with the main 40 amp fuse under the hood of my 1994 Buick Regal. After it blows the gauges do not operate, the power windows do not work and the car will accelerate very slowly in forward (RPM revs are way up at this point) until it reaches 25 miles per hour where by it then accelerates normally. The fuse can last up to 2 weeks or a few hours after replacing it. The power windows are not being used when the fuse blows.

Sounds like there's a ground-out/short on that lead. Best bet is to trace the wire to see if there's a bare spot where it is touching another wire bald spot, or the car body. Also, is there any liquid getting to the fuse and container? If so, that might lead to the fuse blowing as well.

1992 Buick regal 3.8 L has NO POWER TO 20 AMP FUEL PUMP/ECM FUSE AND FUEL PUMP RELAY UNDER THE HOOD.relay does click though when first turn on the key?? only fuse blown was the trunk release.I have swapped...


If the transmission was slipping, there is no fix for that

Being a 1992 i would talk him into parting with it

To old to be rebuilding a trans & you will need wiring
diagrams & most likely more knowledge than you have
to use them, for all the electrical issues

1997. Rav4 no power to fuel pump or gauges


Sounds like the MAIN fuse has blown.
No power to anything.
60-80 amp clear plastic fuse under the hood.
Must remove the fuse box to replace it. Not fun.
Usually caused by the battery shorting to ground.

I have no dash or tail lights on my 94 Buick century


Blown Fuse, I'd bet. Check the owners manual for fuse block location. There are probably two locations on that model. One is usually on the passengers side right side of the dash. Plastic panel that says "FUSES". The other may be under the hood but I would bet the fuse you need is the on on the passengers side.
