Push on the knob that turns the lights on. There was a loose wire on mine and that fixed it for me.

Brake light flickers while driving down the road.


Check the brake fluid. It may be just low enough to occasionally turn the light on as you hit bumps and it sloshes a little. Add a little brake fluid to the reservoir and check the brake pads all around.

The lights on the instrument panels as well as the radio flash at intermittent intervals. There seems to be no rhyme or reason as to when this happens (i.e. hot or cold car, bumps or no bumps, turns or no...


I had intermittent instrument light problem that went dark for months, until today. :o) I read somewhere that it could be the dimmer switch and didn't think that was my problem as the dimmer worked (dimmed the radio and transmission indicator light) and playing with it never seemed to help with the problem. I did find it odd that dimmer was not completely linear, as it would get brighter up to a certain point and get slightly dimmer with the last little bit of travel.

Today, I took the instrument cluster apart to fix a broken clock, sticking gas & voltage gauges, and to explore the instrument light problem. I took apart the dimmer switch, and to my surprise (was expecting a simple POT), it was a very complicated PCB with some IC's, resistors, transistors, etc. I thought, "all this just to dim the light???" Anyway, I found the POT (potentiometer) and gave a few squirts of WD-40 and found it turning smoother. After putting it back together, the instrument light came back and the dimmer is now perfectly linear. Apparently, less than perfect POT causes some sort of funny logic through the network of IC's and transistors and can cause the instrument light to go on or off randomly at certain intervals.

Anyway, I'm so happy to have the light back along with a working clock and not having to punch the instrument cluster to see how much fuel I have. Not really a posting type, but wanted to help someone else out there with a similar problem with same cause.
