Best Answer

GM vehicles typically put fuses in a couple places. First, check under the dash board to the left of the steering column. There is usually an access door that opens to reveal a bank of fuses. Second: GM often has a bank of fuses near the battery, under a cover. The cover usually has printed instruction for removal. Third, GM vehicles often have a set of fuses and relays on the firewall, just below the hood and behind a plastic cover. If you have any questions, refer to the owners manual or go to the local library and look up your vehicle in the Chilton or Haynes manuals.
