Having trouble with a leak inside my daughter's '03 SS. In a heavy rain, a little water begins leaking out of the overhead console. It's been minor so far, but I don't want interior water damage in a near-perfect Monte. So, I opened the sunroof and found the drains, determining that the driver's corner was the problem. First, I blew compressed air straight down the hole, then cautiously snaked a soft thin wire down there to be sure it was clear. I can now put my finger on the end of the drain outlet in the door jamb and while blowing air through, I can feel it coming through the drain clear and strong. But, STILL..the water drains much more slowly than the other corner. I'm worried it's still going to leak. What the heck am I missing ? It's driving me crazy.

 

It may be something other than the sunroof drain. My Grand Prix didn't have a sunroof, and the floor still got soaked on the passenger side. Does anyone know if there are other cloggable drains on the W-body?

 

 

I believe this is why heavy rain makes pools on my passenger side mostly, the cabin air filter seal is worn or came off. Where can I get this plastic cover piece for it? I searched on Amazon, couldn't find it..
