Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hello I will help,
Do you have a voltmeter?
This can get expensive to guess what happened, if you would get a voltmeter (about $20 - 30) it will help pinpoint the problem.
One thng you can do is check the BLO MOT fuse in the left underhood fuse block. The legend is on the cover. It is a green 30 amp fuse.
This is the larger of the two fuse blocks on the passenger side of the engine compartment.
