Two problems related to battery have been reported for the 1997 Oldsmobile Bravada. The most recently reported issues are listed below.
Interior lights flash and flicker. Anytime the drivers power seat controls or lumbar switch's are pressed the flashing and flickering increases as well as battery voltage dropping. Tested by removing the fuse for the power seats, flicker still remains and vehicle still loses battery voltage randomly. Vehicle also responds like it has a dead battery everytime it's started (replaced battery with new one and had same problem).
