Are both lights coming on and staying on? sometimes when a light is out on the front or rear the lights just come on and will not blink.
check ground wire on front of engine behind starter.
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.
When your 4X4 dash lights blink that is indicating a malfunction - could be just a sensor
i dont have an answer, but my 4wd works, the lights just blink randomly sometimes
turn signal relay is bad
You can buy special bulbes that blink your lights slowly or you can computerize them.
replace the flasher fuse
You have a weak ground connection.
you need to change the flasher can for the signal lights
Check all of your blinker lights. There are two in each tail light, one in each center signal, and one at the corner of each headlight, a total of 8 lights should blink when you have the flashers on. If a bulb is burnt out, it will increase the blink rate. Also, installing LED's in the tail lights will cause the blink rate to increase.
It has been my experience that when the blinker comes on but the lights don't blink there is one or more bulbs burned out. If that is not the case check the flasher.
