If you pull the 20amp park lamp fuse and the lights stay on, it almost has to be a short inside the headlight switch.
Will the lights go off if you unplug the headlight switch ?

SOURCE: Blower won't shut off

You will need a Blower motor resistor and maybe a blower motor resistor connector end. If you look under the dash on the passenger side(may need to remove smooth black cover, vents will be sticking out) you will see a connector going straight up into the blower motor resistor(7 wires/slightly in front of blower motor). Pull out the connector and check for melted terminals/wires. If no melted terminals just replace blower motor resistor with part # 89019088 per GM to revert to part before 04 in order to stop blower motor resistor relay from hanging. Let me know if i can help more.

SOURCE: Blows fuses when parking lights are turned on. Headlights work fine even running lights.

If it only happens when you turn the switchto the parking lights then it is most likely the swich that is the problem. Light swich failure appears to be a common fault with fords

SOURCE: Brake and Parking lights won't turn off, even in "OFF" position - Drains battery

Get under the dash ad look at your brake pedal lever. You will see a stop light switch that screww into a bracket with a 'button' sticking out of it. if pulling up on the brake pedal (even slightly) solves your problem, then the switch needs adjusting closer to the brake lever. If adjusting does not stop problem then replacement of brake light switch may be required.

when you say you pulled the fuse, did you pull the fuse under the dash or the fuse and relays under the hood that control these lights?

I replaced my water pump in my 1999 gmc yukon my check gauge light stayed on and temp gauge stayed over to hot side. can i reset it?


Not exactly.
The check gauge warning light is on because the temp gauge is reading hot.
Does the temp gauge read hot as soon as you turn the key switch on, or not until the engine as run for a few minutes ?
If it reads hot without the engine being started, there may be a short in the wiring or the sensor may have failed.

Is there an adjustment for the stop light switch on a 99 GMC Yukon. I have replace it and my brake lights still do not work. Park lights work fine.


There is no adjustment. The park lights are on a different circuit than the brake lights.
Do you have a third brake light that works. Its also on a different circuit but works from the same switch. Do your turn signals work. They use the same filament as the brake lights.
Also, the brake light circuit goes through the multi function (turn signal) switch.

Since the brake lights and turn signal lights use the same filament in the bulbs, the brake light circuit will pass through the turn signal switch. When a turn signal is used it cancels out the brake light for that side.

Let me know if your third brake light and turn signals work in the rear.
Also, if youy have not already, check/change the bulbs. The type of sockets those lights are in also get burned so look at them well.

The parking lights on our 2001 GMC Yukon XL stay on after turning the vehicle off. This drains the battery down to prevent starting again. What is wrong?


Hi, there is a park relay in middle of the interior relay box under the dash to the left of the steering column. This is shown on page 6-61 of your owner's manual (http://www.extendedgmwarranty.com/owners-manual/gmc/2001-GMC-Yukon-Denali.pdf)
With the battery connected, pull out the relay and push it back in. If it clicks when you do this, the headlight switch is bad. If it doesn't click, the relay is bad. Try swapping the relay with another similar relay, such as the horn or A/C relay. If that solves the problem you need a relay. If not, you need a switch. Please let me know if you have any questions, and thanks for using FixYa.

I have a 1994 GMC Yukon and the park lights do not work so now I have no rear lights when driving at night


it sounds like the contact that turns your parking lights on has gone bad. the contact is located in the light switch. so, you probably need a new light switch. make sure you check your fuses first before you replace the light switch. good luck.

My parking lights stay on occasionally after turning the car off. I can't get them to turn off and it drains the battery.


Either the switch ,relay or there is a short in the circuitry. Temporarily (until you have it repaired )remove the parking lights relay or negative battery terminal.

1999 GMC Yukon, replace Low Head Lamps. DRL no longer functional. Hi and Low beams as well as DRL indicator are functioning correctly. Suggestions for Repair!!!


DRL have a diode under the dash that are prone to fail. You can check this by simply pulling the diode connection and using a shunt connect the two wires together and they should light up. Also check to make sure the parking brake is fully released as this will turn those lamps out if the brake light is lit
