Fellow Listers,

OEM Sun roof in 2007 DTS has developed water leak through center roof console that contains garage door opener sun roof controls, etc.  Also leaking on drivers side to the left of sun visor.

Any repair or problem definition advice will be appreciated.

Thanks much,

Generally, there are drains for the sun roof, and if those drains get clogged then the drainage will go other places.  I have not heard of it coming in the garage opener but okay.   It is not infrequent for people to post that their sunroof drains were clogged and needed to be cleared.

Bruce,

 

Once again, thanks.  I'll take a look for the weep holes.  I've also contacted Pete at Paymer & Phillips, Rt. #1, Glen Burnie, MD 800-894-TOPS and he does these repairs.  He does all auto custom work and previously installed the canvas roof , chrome wheel well trim and Gold ornament treatments on my wifes 2000 Deville.  Does excellent work and is a no-nonsense guy.

From the GM DVD manual...2007 DTS...

 

A drain trough encircles the sliding window panel and leads to the drain hoses. The drain hoses are located at each corner of the sunroof module assembly. The two front drain hoses route down the windshield pillars. The two rear drain hoses route down the rear sail and the quarter panels.

If you encounter a wet headliner or other water leak, inspect the following areas for the source of the leak:

    •  The windshield

    •  The rear window

Verify that the drainage system is not plugged or restricted. Use the following procedure:

Using a one pint container, pour water into the drain trough with the sunroof window open.
Inspect for water drainage through the drain hoses exiting the wheel house areas.
If the water flow is restricted, use a low volume of compressed air in order to clear the drain system. Do not blow the drain hose away from the housing drain spout.
Retest the system.
If water drips from the headliner above the door, lower the headliner as required in order to inspect for a proper drain tube connection. If necessary, install new tie wraps onto the drain spouts of the sunroof module assembly.

I am glad you got that leak fixed, I had the same type of leak in my daughters 07 Jeep last month, the drains were clogged with a dried mud like obstruction. 

Thanks for looping back to give us the final result.
