I solved that problem on a 1998. Had to take off the the hood and cowel and right there in front of the passenger seat there's the air intake for the blower motor with a cheapo weatherstripping seal that was flopping all around. Sealed that down with some goop and i havent had any water in years.
Now if you dont have a big leak there you wont get water every time it rains but it will well up in there and splash out randomly.
There's a much easier way to tell if this is your problem without all the work, a two man job, removing the hood. Under the dash on the passenger side you can pull down that blower motor with a few screws. Do it after it rains. If you get wet or see alot of rust on the motor then that's your problem

Ac hose leak?
leaking heater core?

Hint: it leaks when it RAINS

If it were related to the heater core or the AC drain, it would be leaking when it is not raining also, so those diagnoses are not logical.

The grand prix has a long history of floor leaks from seal failures around the air intake under the windshield cowling, where RAIN water runs in.

My 2003 jeep grand cherokee laredo has a problem with my coolant reservoir drains quickly and i also have condensation on inside of window. when i turn on the heater i see dust or steam come from...


Your water heater core is beginning to leak. Eventually, you will find an antifreeze puddle on the passenger side floor which can eventually lead to the rupture of the heater core and a large amount of antifreeze in gaseous form within the cars interior.

It is time for a new heater core. Should you want to go the cheapest route, you can purchase a bottle of copper plugging agent. Ask your local car part guru what he has to plug a leak in the heater core.

Be forewarned: should you go this cheap route, you risk clogging your heater core for good and you will no longer have heat until you replace the heater core.

Heater fan wont blow on any setting on 2002 gran prix pontiac?


There are fuses for hi and low blower fan inside the interior fuse panels I know the high one is on the passenger side and believe the low is on the drivers side tho they may both be on the passenger side read the cover after you pull them off easy to find once you read the label if those are both good then its probably the blower resistor, fuse check first.

My 1997 grand prix gtp has a leak


Is it water or coolant that leaks inside. Water will be clear, coolant will be yellowish-green or blue. If it is clear than it is just a rubber hose that is loose from the AC drain. Replace the hose and clamp. If it is coolant then you have a leaking heater core and would need to get it replaced.

1. My grand prix gtp has problems with leaking on the passenger side. I cannot locate the leak. 2. My engine runs too hot when ideling. I changed the thermostat but this did not help. I need your assi


Make sure your cooling fans are coming on when the temp heats up. Are you talking about a leak inside the car or outside? Inside is usaully a drain tube for the A/C stopped up. Outside, look for a water pump or intake gasket.

Blower motor goes out every so often? Design flaw connected to the wiper motor???


could be that when it rains or is wet out that water is leaking into your car under the hood under the vent by the windshield wipers on the passenger side and instead of being filtered out its going into the car on the passenger side floor. (check to see if this is wet after a heavy rainfall) and causing a short and rusting it out. this happened with my 2002 grand prix just this year. I got a water resistor for like $3.50 from a local pontiac dealership/parts store and put it in. Its easy to install and it poured out today and my car didnt leak at all.
