2001 Boxster headlight dimmer than opposite light

There is a relay (electronic switch) that controls the headlights. It is burned out. They are only about 7 dollars, mounted in the fuse box.

Hi,
Look under the hood for a fuse panel. There should be a diagram on the lid that shows HeadLight Relays. If there is one for the left and right, try swapping them - WITH THE KEY OFF. If that changes the light that works, then either the dealer or an auto parts store should have the relay.

It's also possible the headlight harness is bad - they can overheat and melt. Verify there is no damage to the harness wired from the headlight to the fuse panel under the hood.

If you also lost the light dimmer and highbeams, you may have a short in your wiring, or the 'stalk' on the steering wheel is bad.

Keep at it and try removing it, then re-seating it a couple times. They're really tricky to line up.

If the headlights were not changed at the same time the dim one may be about to go out. If you change the dim one and not both of them the other one will most likely get dim while the other is still bright

dimmer switch bad

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.

sounds like a faulty headlight switch w/dimmer

headlights rlun on high beams at all times dimmer switch is designed to interupt the circuit so id say your problem would have to be at the dimmer switch check the plug and linkage

you have a bad dimmerswitch

If the car beeps twice when you unlock the doors, it means there is a fault in the car alarm system. Usually when this happens the red LED lights on the "door lock" button on the top r h side of the dash. Also on mine, when you try to open the passenger door the window does not drop the small amount as usual, but that may be part of my alarm problem.
