Question about Chevrolet 3500

1 Answer

2007 Chevy W3500 tiltmaster, headlights- Since purchasing the truck new, I have not been able to adjust the headlights properly.  Dealer supposedly replaced the right side assembly, but the lamp still flops around in the housing.  The owners manual shows a vertical and horizontal adjustment screw, but there seems to be only a horizontal adjustment, and the problem is with the vertical.  I was wondering if there is an older or another headlight assembly that would provide the proper adjustment.

    The holes are there for the adjusters, but only one hole on each headlamp has an adjustment mechanism.  I'm taking it over tomorrow and talking to the parts guy first.  Thanks for the help.

Headlight adjustment

I had this problem. The plastic grommet that the headlight fit into was cracked. I got a headlight assembly from CertiFit (cheaper than dealer.) Or try a junkyard.
