1999 Pontiac Grand prix does not blow high fan speed on Max A/C.


if its the same set up as my oldsmobile intrigue there is a plug behind the glove box that has a sensor board, my fan quit working all together and I swapped that sensor out and everything worked fine afterwards, does your right side passenger floor board get wet when it rains hard, if so it has shorted part of the sensor out for the high side of the fan.

Water on floor passenger side after it rains and after air has been running 2000 grand prix


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.

Car wont start in the rain


Hi, your disributer cap must be letting moisture in or it has a hair crack.
REplace it with a new one & also spray some sort of water repellent (WD40) onto the new cap inside & out.
Also smear some grease around the rim of the cap to stop mositure getting in.
This cured a VW that plagued us every time their was either rain or fog.
Also check you rotor arm as well for hair cracks or just replace it with a new one.

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.
