I have a 2003 Suburban with a sunroof and when it rains there is a drip from the passenger side visor where the visor mounts to the roof panel. It leaks on the door side mount. I'm guessing its from the sunroof, but is there a way to find out/repair the leak?

Thanks,

You will need to replace the sunroof weatherstripping and also check for and repair rust under and around the weatherstripping.

 

Sounds good. I will do some research on how to replace the weather strip.
Thanks for the help..

Also you might check the drains to make sure that they're not plugged up with anything.

 

The drains sound like an easier fix. I checked the gasket and it looks good. Where are the drains located? How can you clean them out? A compressor and a blower?

 

The drain tubes will not stay connected with a blast of compressed air. Yours leaking by the visor means the drain tube probably came off the sunroof housing.
Have to pull down the headliner slightly to take a look at it.

 

My 2003 Suburban started leaking a few years ago. It was due to the windshield gasket. It had started to separate from the roof panel above the windshield. I filled the space with silicone. All good after.
