Pontiac Repair: 04 grand prix sun roof, drain hoses, sun roofs


Question
Passenger sun visor and above is wet. Sunroof appears to be closed all the way. Any ideas??

Answer
Hi Gary:

All sunroofs leak! under the roof there is a gutter to catch any that gets past the seal on the glass. If the drains are plugged up the water has no place to go.Also the drain hoses have a tendency to wiggle off the sunroof modules and then the water leaks out. Lastly on that year car the hoses for the sun roofs plug up at the bottom. If you pull off the trim panel on each side of the car under the dash board you will see the drain hoses tucked into the body. Pull out the hose and cut back the ends of the hoses from a flat cut to a 45 degree angle and stuff them back into where you found them There was a service bulletin on that to do that the ends lay up against the body and the water back up the tubes. When they are cut at an angle this will not happen. Good luck :}
