Hit a deer and replaced the front end.

Drivers side headlights(low and high beams) and marker lights are half as bright as right side.

It is not the bulbs, changed them out.

Could it be some type of relay or kinked wires?

Thanks

 

Dim lights are indicative of bad ground. Make sure your new front clip is correctly grounded.


To test this you run a small wire from neg bat to the area near your lights

 

I did paint the area that two of the grounds attached to the frame. So there might be grounded wire in the wire harness for each side?

I hope it is this easy.

Thanks

 

Keep us updated,

 

No solution yet. The main ground for the wire harness is attached to the cable coming from the battery. I separated the cables, expecting the light to go off and no change.

I need to search for a wire diagram and start sniffing.

 

Splice in a new ground wire from the battery to the back of the light bulb plug. Did that on my 2003 Burb and I have bright lights again. Ignore the original ground connections and presume them to be inadequate.

 

You grounded all the lights that way?

 

If I run a wire from the positive to positive, the lights get brighter. If do this with the ground, nothing.

So I'm assuming I have bad positive wire some where.

 

Check the headlamp relay & the connections to the backside of the relay socket. If you run a positive battery wire to the fuse sockets (RT HDLP, LT HTLP) and the lights get brighter, the wiring to the lights are probably OK.

 

It was a fuse burnt out. I just learned something, a burnt out fuse doesn't make the lights not work, just dull.

Thanks for the info.
