I’ve been a water leak and
I’ve been a water leak and wind noise control business owner here in south Florida for last 17 years.. that tech was spot on pinpointing that wind noise but no where near the area code of that spot on repairing it. More than likely he was a trim tech at the dealer and saw a sublet vendor making good money working for themselves fixing water and wind leaks.. unfortunately that material he tried to repair your mirrors with is buttle, which is a pliable non harding non lubricating filler for bad pinch welds in body shop or seamsealer skips that are in interior of vehicle. Chrysler actually uses that material on a lot of their vehicles, I suppose that’s why the techs also use it. But it’s also why I repair more Jeep Chrysler Rams than any other line..the only consistent wind noise from the mirrors was in the first year Rebels.. very rarely do I repair mirrors themselves.. and a very few occasions the base of the mirror mounting plate isn’t fully compressed in the glass run molding.. funny how so many people do and say to change your door weatherstrips, when all your doing is changing an apple with an apple.. compression people, just build a little compression.. the more common leaks I fix I like to keep close to vest. Don’t buy parts for wind noises unless their missing or ripped.. learn to shim and build compression. And if that doesn’t work you just saved yourself a few hundred dollars in apples.. oh and I almost forgot.. don’t put buttle back in your mirrors, squeeze a substantial amount of dialectic grease under the mirror into the base.. be generous and clean off excessive with rag.. will last a long long time with no mess
