I have a 1991 accord lx. 216000 miles on it and recently the lights in the dash that tell you if a door is open or a brake light is out started blinking randomly. Mostly in the morning and maybe when the air is damp. Does anybody have an idea what is going on? I checked the body ground and cleaned it, the one right off the battery. Is there another body ground that could be causing this or is it something else. Car does not run any different when blinking occurs.

Thanks

 

I'd start looking for bad grounds elsewhere in the car, especially back at the taillight clusters.

How do the interior lights work when you open the doors? Each door has a little switch that grounds the lamp circuit, and those can get flaky with corrosion.

 

All the interior lights work great. I will check the grounds in the rear lights.
Thanks

 

I don't have a wiring diagram for 1991, so can't really guess which (if any) additional grounds might be involved. Finding flaky grounds can be a PITA so good luck.
