Noob Question

I have the wet headliner problem. Can somebody tell me where to find the sunroof drain outlets? Tried looking down from the top without much joy, any help appreciated. 1997 GMC Yukon 1500.

This may be a possibility, newer model, but maybe they did not change much.

I had a car with aluminum drain tubes once, It was easy to clean with an air gun.

Thanks, but that still doesn't tell me where the drain exits are.

Ya, GM known how to hide them good. They will ether run down the A piller or come out in the front in the wiper arm area.

This guy shows you kind of how they hide stuff. Not sure why I am unable to find anything on the 97 Yukon. I have had this issue with almost every sun roof I have worked on. I even worked on a few Porsches and was unable to get much help from the manufacturer. Sun roofs are an afterthought from the manufacturer.

Thanks for the vid and response. Still looking, and it's raining today! Can't believe this info doesn't exist for our trucks tho...

I am wondering what year sun roof became an option. I know it was never an option on the trucks in the GMT400 series. Almost everyone I have seen has been aftermarket and went down the A piller and to the ground. Most the time the clog is in the top but sometime a hose will clog. Even the 488 page detailed Owners Manual talks nothing of the sun roof. See if you have an RPO code in the glove box of CF3 - CF4 - CF5 - CF7. I'll do some research, See what I can find.
