I have a 1989 gmc sierra that is having brake light and rear parking light issues. recently my truck was hit from the front and taken to a body shop for repairs. a couple days after i got it back my tail lights started acting up. during the day when parking lights and headlights arent needed my brake lights work fine but when the blinkers are on the are very slow in blinking. once the parking lamps/headlights come on the brake lights nor rear parking lamps come on. what can i do to fix this

Look up under dash where brake pedal pivots, you should see a switch that is activated by pedal arm.

Could be both bulbs have burned out at once. Or could be the brake light switch. The third brake light and the normal brake lights operate seperatly. Or could be the wires.

Check your emergency brake. Make sure it isn't partially pressed in. Try unplugging the switch to the emergency brake and see if the light goes out; if it does the switch is bad.

I have a 1989 gmc 1500 and cant get the brake lights to work i bought a new switch and they still dont work. also i got new bulbs my taillights work but the brake lights do not.


First I would check the fuses. You may have two fuse boxes. One inside and one under the hood. You can check for voltage on both sides of the brake switch to verify proper operation. That's where I would start.

How to replace a brake light switch on a 1998 GMC Sierra 1500.


Hello my name is Israel and I will be glad to help you. Above the brake pedal there will be a small white in color switch with two wires coming out of it. This is the brake switch. You will need to pull the pigtail from the brake switch and then "unscrew" the switch and replace with new one. Connect the pigtail. Adjust the switch so that the brake lights activate with a touch of the brake pedal. Good Luck.

Change brake light switch on 1999 gmc truck


you're gonna have to be on your back for a little bit.....sorry bout the bad news. The brake switch is on the brake pedal itself closer to the top........you will need a small pick to remove the clip holding the switch on....gonna be a little tricky, but it does come off....also you have a electrical connector to remove from the switch also then you can remove it
