Question about 2002 GMC Yukon Denali

1 Answer

Brake lights and crusie don't work

My denali has lost it's brake lights and cruise. All other lights are working correctly. tail lights and turning signals all work. What I think it is, is the brake switch on the brake pedal could this be the fix? Also the cruise stop I think around the same time. I have changed out the brake switch and that didn't help. I also don't see any voltage at the brake lights

Thanks
Sam

1ST THING TO CHECK IS THE STOP LAMP FUSE . FUSES LOCATED LH SIDE UNDER HOOD. THIS FUSE ALSO POWERS THE ACC. CIRCUT IN TRUCK. ALOT OF TIMES, LAP TOPS, DVD PLAYERS ETC. OVERLOAD CIRCUT & FUSE BLOWS.

SOURCE: 2002 YUKON XL Denali no brake lights or cruise

FROM LUSTY KID:

Check your bulbs first, I have lost both headlights on my ford at once on account of the bulbs burning out at the same time. Same thing probably happen, you have one filament out. The lights can work, but if the filament for brake is burnt, you don't see brake lights.

As for the cruise control. Check fuse box first. If OK check vacuum hose to actuator in engine compartment for starters.

Crusie control doesn't work


The brake light switch (which also controls the cruise control) was not adjusted correctly. Also the stop pad may need to be replaced and the part is available or a penny can be taped or glued in place for a temporary fix.

2002 gmc yukon denali xl, cruise control inop after installing l.e.d. taillamp assemblies, know it is a resistance problem, where and what rating of resistor should i install?


It is not a resistance problem. As it operates normally, the cruise control is wired to the stop lamps and will operate only when it sees chassis ground through the stop lamps. When you tap your brake pedal, 12 volts is applied, the ground goes away and cruise is deactivated. Because the LED tails are diodes and only let current flow one way, the cruise cannot see ground and will not set or operate. The same symtoms would appear if you had original incandescent tail lamps and both brake lights were burned out.
The solution will be finding the wire from the cruise that senses the brake lights, and connecting it directly to the brake switch, IF the brake switch is grounded when the pedal is not pressed. You may have a relay wired to the brake pedal switch to make this happen. Seek a knowledeable car audio/accesory shop familiar with auto electrical to help you with this.
Good luck!

I have a 1998 C1500 and the problem is my crusie control does not work and my brake light do not work. replaced the brake booster and that fixed the problem for a little while but problem is back.


You might have a bad brake light switch located at the top of the brake pedal, there's also a cruise control switch mounted next to the brake light switch.

2003 Denali Yukon, no Brake lights, no Cruise Control, fuse is OK


Check your brake light switch at the pedal. This controls the lights and disengages the cruise when stopping. I'd look there before I go anywhere else. There may just be a wire loose. Could be a simple fix.

Good Luck and hope this helps.
