Welcome.
Water getting past the blower motor is a typical problem. Read here..... http://www.grandprixforums.com/how-to-write-ups-tech-tips/6961-water-in-floorboard-take-2-the-permanent-fix.htmlAnyhow my issues are not new:
1) Water in passenger side floor
And the biggie driving me nuts right now:Most likely the ignition switch is faulty. You can change it (the problem will come back again), or just do the Ignition Saver mod..... ClubGP:3) DRL/Heater control issue going off and on intermittently. I changed the key cylinder but that did nothing to help. 2-3 yrs ago I lost fan speed 1-4, so I changed the blower resistor and that fixed the issue but at that time I was not having the DRL going out and the heater control not working.
All the functions work, DRL, Heater/AC, Defrost so I don't think it is any fuses. Right now only 5 speed works if I re-start my car a few times and then it kicks in. I can't get 1-4 to work, when I changed the key cylinder for about 3-4 minutes 1-4 was working, then stopped again.
