Question about GMC Yukon Denali
The parking lights stay on when we turn the truck and light switch off, on our 1999 GMC Yukon. Even removing the light fuse doesn't turn them off we had to disconnect the battery to get them off. Suggestions?
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.

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

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?
