My fan motor on a 2004 Pontiac vibe only works on high, not any other speed, anyone know what might be wrong?

its not the fuse or breaker, dont listen to the other guy, its the blower motor resistor or fan control switch.

yes it is the relay for the spped control. sometimes it is in the switch. but it is the relay

Most likely it is the resistor that went bad. This is a small piece of electronics that reduces the amount of power to the fan (resists) so that it will spin slower. That is an easy and cheap fix. Don't let the mechanic talk you into replacing the fan motor as well. Sometimes, but rarely, the switch itself goes bad.

switch

This is right out of GM electronic service information. Blower motor operates at High speed only • An open between S223 and the blower motor resistor--Refer to Circuit Testing and Wiring Repairs . • A faulty blower switch--Test the blower switch for an open. Refer to Circuit Testing and Blower Switch Replacement . • A faulty blower motor resistor--Test the blower motor resistor for an open. Refer to Circuit Testing and Blower Motor Resistor Replacement . Safe bet....Blower Motor Resistor. The odds of all contacts on the fan control switch going bad at the same time is slim and none. All it takes is 1 circuit path on the resistor to cause your problem. If your vehicle is under warranty....Take it to the Dealership If not under warranty...and you want to fix it yourself....here are the steps. Removal Procedure Remove the instrument panel compartment. (glove box) Disconnect the blower motor resistor electrical connector. Remove the 2 screws (5.5mm socket)and the blower motor resistor from the blower case. Installation Procedure Follow the instructions backwards :) AC Delco replacement part number 15-80202 GM part number 88973260 MSRP $39.58 I found it online $30.53 (includes shipping), i attached a link to the web site.
