your problem could be in the switch its self. unfortunetly they are expensive to replace, i had to actually wire a switch direct to the blinker system.
cheack the wireing
Check the fuses
The two first things to check are the fuse and the blinker capacitor. Both can be replaced very inexpensively.
dealership recall hazard flasher relay
The blinker switch is located inside the steering column housing and is attached to the turn signal lever you move to activate the turn signals. If you are talking about the Flasher Relay, that causes the lights to go on and off, it is located, front seating area, driver side, under dash, mounted above fuse block. There is also a separate relay for the hazard lights. It is located, front seating area, driver side, under dash, above kick panel, mounted in bottom of convenience panel
Try replacing the turn signal flasher
check and make sure all the lights are on like if a turn signal is out in the front then the signal will stay on in the back when you turn the turn signal on.
On the left turn signal lever, twist the end cap to turn lights from OFF - Parking - ON - AUTO
You can't
You should have a dimmer switch on the dash behind your turn signal If the '94 is the same as the '96, then it is possible that the door sensors have to be replaced. In the meantime, remove the bulbs so as not to drain the battery.
MY 1999 ALSO DOES THAT.THE MECHANIC LOOKED UP PAST CASES AND SAID THE ACTUAL BLINKER/CONTROL ARM IS GETTING WORN,BUT NO NEED TO REPLACE IT YET THAT I SHOULD BE ABLE TO GET ANOTHER COUPLE OF YEARS OUT OF IT BY JUST MOVING THE CONTROL ARM(TURN SIGNAL)AROUND A LITTLE BIT.IT DOES WORK!!! KEEP IN MIND WHEN YOU USE YOUR BLINKER YOU MAY HAVE TO MOVE IT AROUND A LITTLE BIT AGAIN.GOOD LUCK!! JERRY Your turn signal multi function switch needs to be replaced, it's worn. It can be pretty pricey at the dealer.
There is no way you can turon signal/blinker in gta 4 as the other cars have. Only the getaway car had signals other cars dont have signals. You can turn the headlights on or off during the day and choose b/w high and dim in the night.
