Question about 1999 Pontiac Montana
Depends on how bad the head gaskets are. I've used it on numerous vehicles motors, and if the problem was minor, it worked. If the problem is a little more than minor, it would be a wast of money trying to treat it, you would be better off replacing the gaskets.

You headlight lamp have a diffuser mechanism which allows it to flip between the hight beam and low beam feature of the bulb. In fact, you high beam will function even if the low beam is not working.
I would recommend the purchase of the new headlight lamp. It would cost you you any where from $15.00 per unit to get a replacement lamp

I went to bulldogsecurity.com and looked up the wiring diagram for this vehcle. However, prior to checking this part, I would check to see if you have a blown fuse. It doesn't hurt and only takes a few minutes. There should be a fuse for that either somewhere on the side of the dash or near the brake pedal area. If not it may be under the hood, but it should be inside the vehicle. You may have multiple fuse boxes. If it has (2) sliding doors it will have a wire for the auto doors in each kick panel (under the plastic trim/molding) when you open the door and look down you will see all of the trim/molding it should snap out or may be held in place with a screw or (2). Once you remove that you should see the wires. It says for the left side it is either light blue or black and the right side is definitely light blue. Trace this wire until you find out where it ends (the motor or switch to control the auto doors) Then test the switch/motor to see if it is bad.

I am assuming that the DIC does not "power-up" at all.
Check your owner's manual to see which fuse powers the DIC. If the fuse is OK, you need to get your hands on a wiring diagram and remove the DIC from the dash so you can check to see if you have a good ground on the ground wire to the DIC. Then check to make sure you have battery voltage to the B+ circuit to the DIC. If the proper voltage and ground are present, you will have to take the DIC to your local dealer for repair. Many GM dealers have an exchange program where you can turn your old DIC in and get a "remanufactured" one on the spot. Others will send your DIC out for repair and call you when it is returned to them.
