left headlight

2003 Cav LS Sport Coup I noticed the left headlight was very dim. I installed a new bulb and it is still dim. all other lights work normally with the exception of a right side marker light is burned out. All of the connections are clean (no corrosion). Can anyone help? Thanks in advance.:banghead:

Did you check your fuse box? a blown HDL fuse will cause them to light up, but driver side be dim. Normally thats the one to go.

all fuses are ok I've heard that a bad ground would cause this, but it looks like the headlight harness shares the same ground for both left and right. So I believe the bad ground theory to be wrong unless I'm wrong and their are two seperate grounds for the headlights. I'm at a complete loss here the car has only 12,000 miles on it and no warranty.:runaround: I don't want to start tearing apart the harness to find a short If I don't have to.:disappoin Please anymore ideas!

i have the same problem with our 99 z24 my brother in law works at a garage and told me its a common problem with the cav and the sunfire it is a wiring problem the sockets have constant power and when the switch is turned on the ground completets the circut you have to take out the batery the washer fluid bottle and trce the wires he said the way they are designed water and slat gets up in the and messes the wires up unfortunatly this is the only thing i know
