AC fan only working on highest setting

Hey everybody, the fan for the air conditioning in my 2000 GP is only working when it is set on full blast. Does anybody know why its doing this and how to fix it? thanks

It sounds like the relay has gone bad. I believe it is underneath the passenger side dash board. I think u can access it from underneath.

Replace your blower motor resistor - the high speed relay is part of that module- follow purple wire backwards from blower motor to find the module.

Sorry, that is the part I was looking to say - the blower resistor. Thanks

Thanks guys. Sounds like that may be the problem. I'm going t check it out today.

just a tip, if it is the blower resistor (which I agree is the problem) the back two screws that hold it in only need to be loosened (not totally removed). They are hard to reach and this will make replacement much easier. Also, removing the blower motor (it's held in by only 3 screws) will make access to the resistor much simpler.

a 2000 GP is highly susceptible to the famous water deflector coming loose. Water can ruin the blower resistor and blower motor- from air intake that the deflector has dropped off-- check under air inlet cowl for rubber deflector to be unglued and fallen down on top of blower motor air inlet.

Do you ever see water on passenger floor after a rain?
