There is no way to disable the DTrs while driving, they are a safety issue. To turn off the DTRs, push down slightly on the parking brake pedal and the lights will go out.
push your parking brake one click and it will turn them out
You have to go to the Ford Dealer, and have them turn it off in the computer.
To fix or disconnect the daytime running lights on a 1999 Grand Prix, you could begin by checking the running light fuse. If the fuse is damaged or blown, you can replace it to fix the lights. Remove the fuse if you want to disable to the lights.
No Relay, Just A fuse located on the drivers side dash when you open the door. It is under DLR (Day time running lights) silver finned box under dash, right side of sterring column
On a 2008, fuse 13 (10 amp) located inside the fuse box in the engine bay controls your DRL. Removing it should disable your lights.
I am not familiar with the Tahoe but when both headlights go out on any car at the same time it is not usually not that both bulbs burned out at the same time. Usually something happened to the electricity. First you check for a fuse. Information about the fuse box will be in the owner's manual. Next, you check the switch to see if it has electricity coming out of it. If you have electricity leading from the light switch to the running lights, then you check to see if you have electricity going into the running lights. If you do, you have burned out bulbs or a bad socket. Otherwise, you have a bad wire.
make sure that the parking brake pedal is all the way up, it is a feture that if this is pushed in that the lights will stay off. hope this helps
Day time running lights are for saftey. They are design for notifying on comming traffic
Day time running lights?
in the parking lights
do 1998 ford f450 have day time running lights
vehicles equipped with day time running lights are designed to have the running lights on when the vehicle is running in gear.the only time you can change that is by turning on the headlights, or turning off the ignition. some running lights go out when the transmission is put into park. ( the only way to change that is by manually disabling the lights, like cutting wires, or breaking bulbs)
