Answer 2

The headlights on a 2004 Pontiac Montana are adjusted by turning the screws along the back and side of the headlight assembly. They control the horizontal and vertical movement of the headlights to allow for precise aiming.

Answer 3

Although mechanics use a highly accurate headlamp adjuster to ensure that both headlights are pointing in exactly the right direction, in a pinch a screwdriver will fix misdirected beams enough so you can safely drive in the dark. Steps: 1. Park your car on level ground with the headlights about 10 to 15 feet from a wall or garage door. 2. Find the adjusting screws for the headlights. They will probably be inset adjacent to the headlight. You'll find a horizontal and a vertical adjusting screw, with small springs behind them. Some cars come equipped with a small level (like a carpenter's level) attached to the top of the headlight under the hood to help you get the correct adjustment. 3. Turn the headlights on. 4. Notice where the light shines, using the wall or garage door as your gauge. Check for uneven or cross-eyed light beams. (Image 1) 5. Turn the adjusting screws with a Phillips screwdriver while looking at the wall. Turn slowly and continue to check the wall (see illustration) until the light beams are even and tilted slightly downward (so your car's headlights won't blind oncoming traffic). 6. Test-drive in the dark and repeat steps 1 through 5 as necessary.

Answer 4

This is very simple. First remove open the hood and remove the four screws with a 1/4 head head from the top of the front grill assembly then remove the fith screw located just above the GMC in the center of the grill. Next remove the eight Phillips head screws the that hold in the turn signal assemblies you can either leave them hang remove them(they will slide through the grill as you remove it.) Next you will slide the grill assembly forwrd there are retaining clips left, right and center. You can lift up on the left and right ones the center one you have to push down on. Remove the side light indicators and remove the grill. The exposes the headlight assemblies four 10mm hex heads and they come right off. Reverse the process to put it all back together. The whole thing should take about 30 minutes.

Answer 5

If you're removing the headlight assembly,you'll need to remove the turn signal light lenses,then the grill. From there you will see four bolts to each headlight assembly. It's pretty straight forward from there.

1994 Chevrolet Astro headlight bulb replacement: Purchase the correct replacement bulb(s) first, before disassembling the vehicle. See sources and related links below for replacement bulb information. Then consult your owner's manual for the replacement procedure. As simple as it sounds, the owner's manual is the best place to start for bulb replacement instructions and illustrations. You may want to consider replacing both left and right at the same time in order to keep brightness and color equal (optional).

Answer 7

There are screws on the top and sides of the lighs to adjust them. I laike to get on a dark road at night and adjust them being careful not to blind oncomming traffic.

Answer 8

There should be adjustment screws located along the sides of the headlamps themselves. You may have to take the bezels off of the headlamps to get at them (but I don't think so).

Answer 9

Pop the hood and under the hood on each side above the headlights are 2 bolt sticking up take those out and pull the light out.
