Having problems with your 2002 Pontiac Grand Prix ?
Water leak from under dash
\015 Water leaks in on the riders side under dash when it rains. Is their a drain hose from the fresh air intake by the windsheald?\015
There should be one under hood on passenger side, sticking out of firewall that may be plugged up. Take a piece of coated wire or similar and stick it up in there and see if it's plugged & clean it out, but be careful, don't jamb it too hard & poke a hole in anything like heater core back in there. If it's plugged, it will sometimes back up into interior of vehicle.
