The brake lights on a 96 Jimmy are operated by the brake light switch, mounted on the brake pedal assembly. If the switch is bad the lights could stay on or off, or be sporadic.
Bring to a shop that has an ABS scanner to determine the problem
how to trouble shoot for gmc back up lights?
Check the brake light switch. It's probably attached to the brake pedal, under the dashboard.
The GMC dash tail and parking lights are on a different fuse from the brake lights. Check the fuses for a possible blown fuse.
Check bulbs they are double filamented smaller for brake lights larger for tailights Check fuses Check stop light switch
Did you replace the fuse? have you checked the circuit board well the lights go on cause they tend to short out often
There might be a separate fuse for the lower brake lights ( just a guess )
Try changing the brake light switch located on the brake pedal shaft under the dash. There's a recall. google "multifunction switch recall jimmy" your dealer should fix it for free.
You need to be more specific about your problem, e.g. starter fails to work, lights do not work etc
In the compartment that holds the jack for this model, look for the wires near the rear it should be by the brake light but inside the vehicle. There should be a connection there for the light. If there is corrosion or a loose wire this would cause the problem of the passenger side working and not the drivers, I researched this dealing with no lights except the 3rd light working during braking, turns out it is the trailer harness connection.
It will either be a mechanical switch located on the brake pedal lever under the dash, or a pressure switch located on or near the master cylinder.
I am guessing, but since I had this problem perhaps this will help you. You must replace the entire switching mechanism that contains the cruise control, blinkers and hazard lights. I replaced mine and it all works just fine again. This is actually a common problem with these SUVs. You can order the part online for only $99 at 1A Auto.
Begin by removing the brake lines from your 1995 GMC Jimmy brake booster. Remove the brake booster retaining bolts. Reverse the process to install your new brake booster.
it is basically a person vs self which is when a person has a "problem" agains nature. example. Jimmy had trouble getting home because he got stuck in a blizzard. nature caused the blizzard and jimmy had a conflict with it.
Hand brake? I thought the last GMC with a hand brake was in 68, but I could be wrong.
The only way you can completely turn off the headlights is to push in the emergency brake slightly, then start the truck and leave the emergency brake on the slightest setting, and the running lights will stay off. Obviously the brakes will be slightly engaged, but you can adjust the emergency brake so the first click doesn't engage the brakes.
Left Of Brake Pedal
Located at the upper end of the brake pedal under dash area
Check the brake fluid level in the reservoir, if it is low you have a leak somewhere.
I have been researching for a fix to get my dash lights working again and have come across your problem and the fix seems to be that you have to change the ignition switch which is a wire harness under the steering colum attached bellow the key cylinder. If you look up jimmy ignition switch you will find the info you need.
Yes. One switch is for the left and right brake light assemblies; and, the other is for the 'third' brake light.
I have replaced the entire brake system in a 1988 gmc jimmy and still have no brakes can you help/
