We might need a little more information. Do the lights flicker every time you switch between low and high? Have you noticed that your turn signal stalk feels gritty or mushy? When you switch to high beams, do they ever flicker later, or just when you switch them? Do they ever go out entirely? I'm thinking that maybe the turn signal switch might be bad, but it's hard to say with no more info. FriPilot
Sometimes the ground strap to the body of the car can come loose. This will cause things to flicker. Ground from the battery needs to be connected to the engine block, the frame, and the body to keep things working properly.
you probly just have a bad conettion just take it to your local shope it shouldn't be over 50 dollars to fix.
The alternator may be failing. Drive to your local auto parts store and they can test the charging system for you for zip.
Have the alternator tested. I would suspect one or more of the diodes in the alternator are bad.
On a 1999 GEO Tracker, a bad fuse can cause the headlights and dash lights to blink. A bad voltage regulator or alternator can also cause lights to blink and flicker.
Yes
It is idling to low, it may be in need of a tune up.
bad or failing alternator
Bad ground on the brake lite circuit.
I would also like to know this. Our van's healights and dash lights both flicker. The headlights are not very bright.
Alternator
I had the same problem. It was my alternator. Be careful, mine died on the way home.
