my 91 civic hatch has done it again...last winter had an intermittent issue w/ dash lights not working here & there. I'd hit a bump & they'd go on/off, etc. They'd be out for a week somtimes longer, then go back on and stay on for a day then be back out again. I know nothing about fixing cars so had a honda place look at it & they replaced the bulb said it was bad and lights worked good for a couple weeks-then out again! Then they miraculously worked all summer, until recently cooler evenings (60 degrees average) and now they went out again, been out for last 2 weeks-driving me crazy! Anything less than 75 degrees & they go out-that and bumps seem to be the determining factors whether they work??? How do I check the fuse for this? Or the ground? OR should I just have the whole gauge cluster replaced? Would that even fix it?
