I've got a '97 Tahoe with an annoying problem. The other night while driving, my dome light flashed on and off everytime I hit a bump in the road. I can't say for sure if any other bulbs lit, becausethe dome light would catch my attention first. I can hear what sounds like a relay clicking in the dash area each time. No doors, nor rear tailgate were ajar. The interior light switch was in a normal mode, but if memory serves me, this happened some time ago when I had the dome overide button on. I'm thinking that the switch itself may be defective, but don't want to just change it to find out. Has anybody else experienced this problem and found the cause?
