Has anyone gone through the car wash with their windshield lightbar?
Yes. Pay attention to the other responses, as damage is always a potential, and the carwash is not going to care whether your
junk is damaged, but will scream bloody murder if you damage theirs
. The only automated wash I use is one of those tunnel washes that has people working it. So if there's going to be a mechanical hazard to their stuff and they accept the rig, the damage is on them. But this is a place I've done a lot of business and they know me, so unless it's someone new, they know we've already had the conversation about, "We're not liable blah, blah, blah." Honestly, for the most part, if a carwash can damage it, it doesn't belong on my Jeep.
On the other hand, I have had to reset my light bar aim, and also had to replace a windshield wiper after going through that wash. They agreed to replace the wiper, but by the time I got around to going back with the receipt it had been so long I didn't have the brass to ask them to pay for it. Not that big a deal, and probably needed replaced anyway. Again, if a carwash can break it . . . If I had to guess, I'd say they probably left it sticking up after their preliminary scrub on the windshield. Can't see it doing what it did any other way.
Just go in with your eyes open, or don't go in at all.
