What did you do to your NNBS GMT900 Tahoe/Yukon Today?

Put my New FLORIDA license plate on my Denali. The winding path it took was amazing. The DMV CLOSED due to Corona shutdown but was taking mail in applications. The first VIN verification from was REJECTED by the DMV.... some officious lady called me and explained the form was "altered" ....grrrr. There was a correction but it all matched......

Changing from Michigan to FL saved me a bunch of INSURANCE $ and will save registration costs. The annual registration renewals cost more than my 2017 Camaro SS.... Crazy

That’s a lot of water.

Do you have a sunroof? If so, check your two drain lines at the front corners of the sunroof. I use string trimmer line to snake them out.

I would also check your OnStar antenna to make sure it isn’t loose.

You could also use that canned compressed air to blow out your drains. The type you use to blow out your keyboard.

i have to the close the shade on mine when going thru a carwash or it pisses a few drops on me thru the glass seal but the corners have never leaked and it doesn't leak when it rains, just from the high pressure water spray, I have read of some people cleaning the drains out with air pressure, you can try poking something down the drain hole's but from what I understand the drain line is plastic down inside I wouldn't try to force it.

That's more likely from the antenna and not the sunroof drains. Put some clear RTV around it and call it a day. But remember, those rollers will rip the RTV away too after time.
