Replaced bulb on my 2007 dts left front headlight but it will not work. it appears that i am getting power to the area. help

Bulbs are too big. Try bulb #194 in them.

owners manual will show you how replace headlight bulb.but wear clean gloves when handling and installing new head light bulbs. because oils from your fingers or hand could cause new halogen bulb over heat blow out besure wear clean gloves.

This is often caused by a faulty bulb - replace it.

Check for power at the socket. If there is no power I would suspect the flasher relay wich supplies power to each bulb individually after it gets the right or left signal from the switch.

The turn signal circuit is different from the parking lights. So the headlights would not be involved.
You should have power on one side of the bulb for parking lights and the other for turn signals.
If you have no power for the turn signal circuit, I would look at the turn signal switch. It powers each bulb separately.

mporteous, It sounds like you have a light switch problem. I can't think of any other reason for the running lights and tail lights not working in this situation. Are your brake lights working when the headlights are off and how about when they are on? Do your four ways hazard lights work in these situations? Try all the lights under these conditions. The reason the left turn signal blinks very fast is because one of the bulbs are burned out. Try the left signal and one light (front or back) will stay on and the other will not come on at all. Replace the bulb that does nothing. Do this before you try all the lights in different situations. I think that you will have to replace the light switch. Good luck with this.

Hello,

To replace the headlight bulb of Your 2007 gmc yukon is not that difficult, please follow the steps below.

1. Turn off the car,
2. Remove the negative terminal head of the battery in order to avoid shock when working on the headlight,
3. Pop hood open,
4. Remove all and any self tapping screws along radiator area.
   
5. You should be able to pull whole headlight housing area forward a few inches, you'll need this to see what you're doing.
6. you have to cut through the rubber lining behind headlight.
7. From there you can reach the bulb,

Hope this helped. Thank You for using FixYa!!!

ok, In this New of a vehicle there are no screws holding the headlight in if you just need to replace a headlight because it is burned out. Look at the back of the light where the wires attach and you should see the wires going into what appears to be a coupling. Get a hold of that and turn. After it unlocks you can remove and replace the bulb. If you are replacing the Headlight assembly because it was damaged there are typically 2 long scews on the top front that appear to be adjsutment screws and 2 smaller ones in each side, again on top. Good Luck

The headlight assembly is accessed from inside the fender well. There are two pop out plastic rivets and a small (4mm? head) body screw that secure the fender liner to the fender. Those need to be removed. Pull the fender liner back enough to work your arm into the fender. Locate the wiring to the headlight and grasp the plug. Rotate it to the left until the bulb is free of the reflector. Pull the lamp and wiring out from behind the fender liner. Remove the bad bulb. There is a release tab on the plug. Insert the new bulb into the plug. DO NOT touch the bulb glass. The oil from your skin can cause the bulb to explode when it gets hot. Hold the plug and work the bulb and wiring back to the original position. It is a little easier to look through the headlight lens as you work the bulb back into the reflector. Turn the plug to the right until it is properly seated. Replace the two pop out rivets and the body screw.

You should replace the headlights in pairs. I didn't and the right bulb went out in a couple more weeks when the weather was much worse. The right bulb was more of a pain to replace than the left, probably because I am right handed.

Hope this helps.
