Wiring diagram for right front headlight on 2001 pontiac grand am

This is for a 2001 grand am not sure if will help ya

if it is that bad , go to a wreckers / junk yard and get the full wiring harness and replace the existing harness
wiring diagrams are in the workshop manual available from ant auto parts shop

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.

I am sorry but we do not have wiring diagrams.

Hope helps qith this (remember rated this help) Good luck.

A loose ground wire to the headlight will keep it dim,Or a headlight adjustment will bring the headlight up.If you can have your headlight turned on a garage door or something at night,and then watch as you change your headlights from low beam to high beam which ones are higher.the last thing to verify is that your high beam headlights are not the plastic lens type that turn dull which cuts the light power.
