Question about 2003 Pontiac Grand Am
My driver side headlight is dimmer than the passenger side
Check for corrosion in the bulb socket or wiring connection points. This could cause a voltage drop, resulting in a dimmer light. If it looks good, then just replace the bulb with a new one. Use dielectric grease only in the bulb socket to prevent corrosion. Do not use regular grease because it will stop electricity from flowing.

SOURCE: Looking for wiring diagram for
You'll need to pull the door panel and check for power and ground at the 2 wire connector located near the window motor (there should be a dark blue wire and a brown wire). With a test light there should be power on one of the two wires at any time. If there is power on both wires with the switch in the up position than the switch is bad. If the only wire powered up in the up position is the dark blue wire than try tapping the motor while holding the switch in the up position. If it starts to work than the motor is bad.
On a side note check for power with all the connectors plugged in. You can also jump the connections at the motor. Supply a ground to the brown wire and supply power to the dark blue wire and the window should go up.

the top wire on the light bulb H4 type i think but not sure is the earth wire and this earth is faulty and not making a good contact to ground ,so renew the earth wire and then see what happens as the light will be bright and it may affect this gauge if the current is backfeeding along the other main beam wire ,I wouldnt count on this though as sorry about this but iam a europeon mechanic whos never seen this motor but this is your fault iam sure .best of british with this endevour

Use a test light to determine which wires are which.
Then follow the same pattern as the other side.

Testimonial: "The light was actually a HB1/9004, even though the package said HB5/9007. I removed the black wires from the connectors and placed the original wires in their place. Put in the old bulb and it worked."
