Question about GMC Suburban

1 Answer

I have an 86 gmc suburban. There is some kind of brake control box under the dash that controls the brake lights. The brake lights have been coming and going. My brother in law showed me this box under the dash that has wire connectors with several wires plugged in to each side of this box. He told me to pull the clips with the wires inside off and spray them with wd40. I would do that, plug them back in and the lights worked again. This no longer works. I need to replace this box but have no idea what its called to see if they have it at an auto parts store.

98 Chevy K1500 that the daytime running lights won't come on, I've tried the control board under the dash, fuses are good. I also tried the relay in the fuse block. The green light in the dash comes on but...


Sounds almost too simple but have you checked the wiring to the parking brake. If it is depressed enough to light the brake light in the dash the DRL's will not light or if the wires are not hooked up same problem. You also state you have checked the control board under the dash I assume you are talking about the Diode an aluminium finned box a little bit larger than a deck of playing cards under the dash on the right side of the steering colum at the swell in the dash. remove this diode and insert a shunt in the connector and see if those babies light up if so its the diode

My turn signals and brake lights are not working (97 GMC Suburban). reverse lights work fine. it is not a bulb problem i tried to change them. one of the circut boards for the lights is new. not sure if...


Does your high mount stop light work? If it doesn't, then it'll be the brake switch located just above your brake pedal.

If the light does work, then it should be the electronic flasher module that will be located under your dash near the steering column. It will be labeled. This controls your signals, but I believe your brake lights are also on the same bulb as your signals, so when this goes, it can affect your brake lights

This was the procces on an 86 chev 1/2 ton. Should be the same. Remove glove box. Undo manual controls for duct work. you'll see them there behind where the glove box was on top of the heater core housing. Bemove screws/bolts. Don't remember how many there are. Undo hose clamps in the engine compartment. Remove heater core.

How do you install an electronic trailer brake controller in a 1995 GMC Suburban 1500?


a brake controller has 4 wires on it, Black, white, blue,red.

Black is positive battery 12 volts connect to 30 amp circuit breaker to the battery

White goes to good solid ground

red connects to white wire from the brake switch

blue wire connects to 7 way trailer connector at rear of truck. If the truck has trailer package you will find the blue wire and red wires under brake booster taped to the harness you can connect your blue brake control wire to that blue wire. At the rear of the truck the other end of the blue wire will be taped to a harness under the rear of the truck. you will have to now connect the blue wire to the blue input on your 7 way connector

99 chevy silverado 1500 running lights.....


Remove the fuse! The fuse box under the hood has the DRL (daytime running light) fuse. The underside of its lid should tell you which one. Either that, or just remove the bulbs from their sockets.
If ALL the lights (head, tail, dash,etc. are coming on all the time), then those aren't DRL's. There's a light sensor (little round black dome) on top of the dashboad in the middle front nearest the windshield. They sometimes fall down inside the dash (where it's dark!) and this triggers all the lights to come on when the ignition is on.
