2001 Pontiac Grand Am Se headlight wiring diagram

Use a digital multimeter check for proper voltage. You also need to check for a good ground. In the diagram, the top wire at head lamp is voltage, headlamp switch on. The bottom wires are ground. Your headlamp switch/dimmer are part of the ground circuit for headlamps. You might be able to use redundant ground with jumper wire to see if lamp will brighten? If it does, problem on the ground circuit, either wiring itself or headlamp/dimmer switch.

The person asking this question has a PONTIAC GRAND AM SE, NOT a Grand Prix. (Not the same car).If you will go to any local auto parts store they will carry the repair manual for your car. The repair manual has the wiring diagram for all the wiring in your car in the back part of the manual. It will be called the HAYNES Auto Repair Manual for the year of your Pontiac Grand Am SE. I just dont understand how some people can be so ignorant as to excessively cut wiring out of a car when they dont even know what they are doing. Go figure. lol. If there is a college or a trade school in your area that has courses for auto mechanics , most of them repair cars also. They usually do not charge a labor charge, they only charge for the parts needed to repair a car and also a small shop fee. If this is the case in your area give them a call asap. They can help you. I used to have a 2002 Pontiac grand Am SE 1. I now have a 2004 Pontiac Grand Am SE 1 and I am going to sell it. If you need any more help just respond back. Hope this helps.

The common problems with DRL system is wires open circuit near the windshield washer tank. The wiring harness to the headlights.

You have to find the wires that are in open circuit or corroded
hint : after removing the isolated tape pull each wire one at a time and you should find the open circuit
hope it helps

sometimes the connecters get on in the headlight switch and melt the plastic holding it together making everything loose.. my mustang did it. i just took the casing off and wired everything directly to it

I am sorry but we do not have wiring diagrams.
