If the flashers work, change the fuse. It is located behind the ashtray/cigarette lighter area. You'll need to remove the cover, the fuse was a pain for me to locate when I had to change mine. But that is where mine was, and that fixed my problem. Hope this helps you.
There are two flashers, one for the hazards and one for the signals.
I don't believe that GM used inertia switchs on their cars. That's Ford. GM uses a simpler, and better system. If there is no oil pressure, the fuel system wont turn on.
remove the tire and brakes then pull them off if they wont come off use a hammer or mallet and that should free them up
check the fuse first!
I replace my flasher fuse.Now they light up but won't blink.
replace turn signal flasher, hazard flasher is separate
The 1990 VW Jetta turn signals will not work when the ground wire is broken or corroded. The turn signals may need the lightbulb's replaced.
Most likely a bad turn signal flasher or blown fuse
have you tryed all the fuses then check if the bulbs are good
If the turn signal bulbs light but will not flash, the flasher relay is defective, replace it.
Could be the flasher unit.
replace flaser can in fuse box
