92ss. ok so when its raining i get a abs, battery, and brake light. also the dash light brightness is at max. the car runs fine when this happens, and it goes away and comes back on when it wants. havent figured out if there is a pattern yet. im wondering if anyone has had this problem, also what could it be?

Probably just the sockets on the bulbs. When you hit the dash do they come on?

nope. it only really happens when it rains.

Does it only happen when you have the headlights on?
It kind of sounds like an illumination control or dash lighting ground control is shorting to ground.

it does it more when the lights are on. only 2 or 3 times during the day. were woul this said ground be?

Anywhere in the harness between the illumination control and any of the dash bulbs or on the back of the gauge cluster.
I'd pull the cluster first and look for anything irregular.

thanks i will do that since the car isnt goin anywere right now.

might want to doubble check the charging system
when my alternator went on me those 3 lights lit up instead of just the battery light. they all went away once i changed it

hmm might have to check that. i have a known good one in my other car so i might swap it.

just check the voltage at your battery with the car running
it should be around 14.5 volts at 2000 rpm
and not too much lower than 14 at idle with accessories on.
usually the light gets set off if its at around 12 i think so just carry a simple multimetre with you and check it when the lights come on.
