Check the solenoid switch on the electrical panel under the hood. Just switch the solenoid for the lights with one of the others just to test it. This is a cheap thing to replace.

2007 Yukon Xl Denali can the headlight switch/dimmer cause only the tail lights to not work. Dash lights, signals, brake lights when pressed work. Both sides went out. No blown fuse or broken wires.


If front park lights are working highly unlikely headlight switch is the issue. Is the vehicle equipped with a trailer towing package and wiring to the rear? I would start there. This vehicle may also have a taillight module located under the vehicle on the passenger rear attached in the wheel well area that goes bad

NO LOW BEAM, EVERYTHING CHECKS OK . I HAVE CHECKED ALL BULBS AND FUSES


Hi,
The simple answer may be that the low beam side is burnt out. Replace the bulb.
However, if both headlights have stopped working when switching to low beams, there may be a problem with the relay or the switch itself. If the cost of a relay is low for your car, it may be less expensive to simply replace that component than to have it diagnosed in a repair shop. Replacement of the switch requires some disassembly of the steering column or dash in most vehicles.
This is how to fix the low beam..
1.Check your fuses. The plastic panel covering the fuses should have a diagram detailing what each fuse covers. If yours is missing, or unlabeled, check your owner's manual, or a Hanes(tm) or Chilton(tm) repair manual. Often if a headlight is not working, it is the result of a blown fuse. Fuses have a wire running through them that will melt when too much current is run through them. If the fuse is blown, the wire will be broken. If the fuse for the headlight you are working on has an intact wire, it is likely the problem lies elsewhere.
2.Swap the headlight for its twin. If your left headlight does not work, put the light from your right headlight in its place. If it works with the other headlight in place, your headlight bulb is dead, and needs to be replaced.
3.If this does not work, try using a voltmeter on the plug for the bad headlight. Turn on the ignition, and turn the headlight switch. If the voltmeter shows no current, then either your switch or the wiring leading to the headlight has gone bad.
4.If replacing your headlight switch does not solve the problem, then there is a break in the wiring leading to the headlight, and the wiring will need to be replaced.

Headlights not working


Ok Guys Thanks I will check into the dimer switch first, But if it is the turn signal switch assembly with the high beam control on it, it will not be cheap, I think they run about 260.00 each.

Thank you for your input.

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.

2002 Yukon XL - No Headlights


Check the headlight fuses in the engine fuse box compartment. Not sure if the lights have relays, but they will be clearly mark in the inside of the top cover for location.
