Heater problem
1999 Oldsmobile Aurora V8 Two Wheel Drive Automatic 147000 miles
----------------------------------------------------------------
I either have a water leak into the heater ducts or a blocked drain. After a heavy rain the passanger side floor was wet. Saw water dripping off the heater fan. Took it off and found about 1/2 gallons of water in the duct works. I can't find a leak and don't know where to find the drain (if there is one)
