My H3 is leaking water from the mic where the onstar is. I am thinking the drain may be clogged or I have some dirt in the track. Worst case scenario is I am going to have to replace the seal for the sunroof. Has anyone done this and if so how hard was it to do?

 

It is likely your 4 sunroof drains are plugged. Do a search here for detailed info on how to clear them and modifications to keep them from getting plugged in the future.

 

Once it's cool enough to crawl under my dash/ fenders I'm gonna cut off the end sacs to the drains and then silicone the dang tubes together...... So tired of this issue...

 

I did this last night and could not believe the amount of crap inside it. Thanks again

 

How did you do it? Mine is bad...I searched on here but still dont get where the drains come out...or what they look like. Not a car guy. lol

 

Avoiding leaks is the reason I baught a hard top..XD

Own a few T-top cars and you'll start to appreciate a solid roof.lol

 

Rod or blow out the drain tubes once or twice a year and the sunroof is trouble-free. Takes all of 5 minutes, tops.
Don't need to worry about where they come out unless they are so plugged that the compressed air or trimmer line cleaning doesn't work, which it usually does.

 

Let me know if you need me to email you the instructions on how to do this.

 

That would be fantastic. Thanks.

A search would have found it for you.
