Headliner burn marks on the headliner

you guys running extra lights (other than factory installed) on the roof?

 

Dealer probably fixed it for free just to keep you as a Paccar customer.
In 35 years this is a first , is your outfit running OEM lights or aftermarket.

well, i never heard of the mirror reflections doing this, unless everyone has thier mirrors pointed into the sky. in all my years, i have never had any such issue, and many times, the trucks i was driving or assigned, were old ones. the new trucks i drove or had been assigned, my mirrors were adjusted to look straight back, not up, or down, but straight to the rear of the rig.

the ONLY thing i have witnessed and seen on some websites, is the skin condition a driver gets on his left arm and part of his face, cause the sun is bearing down on him/her.

sun fade can and does happen to nearly any motor vehicle, as the sun's rays come in from the windshield or side windows.

but a headliner, melting, due to the mirrors?

sorry, i don;t buy that.

 

Sun light ray deflections from shiney objects or through holes in a wall or roof ain’t no joke. They can be bright enough to burn your eyes like a light from a lazer or welder. Makes me wonder what the material would do sitting out in the bright sun light not in the truck. Melt? Must not be very fire resistant either.

 

well, it's a mystery to me. i ain't never heard of this happening...so, either the mirrors are incorrectly adjusted, or the so-called technician from the PETE STORE, is a newbie, and doesn't know how to adjust mirrors.

good luck in finding the problem
