Possible electrical problem
Alternator is failing.
Might be a weak battery
I had this problem and it was a bad alternator.
You may have a pull on your batt, or a surge.
Sounds like you need a new battery.
Check the fuse or switch.
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.
On my Lexus I had an issue with the lights staying off when it was cold. This was the case for all of my dashboard lights. Then they would flicker back on. There are Caps on the board for the instrument panel that were blown. This was the case for my fuel cage that didn't work consistently work as well
Under the passenger side of the dash
Well its possible the lights are blew or the wires aren't hooked up right.
Your entire automobile electrical system is grounded to the frame of the vehicle. A loose or corroded ground wire can cause the dash lights to Flickr and the car to stall out.
