Fan speed for heater only works on high

It needs a blower motor resistor. You have to remove the glove box door to access it. The resistor is attached to the black plastic heater box with 2 8mm hex head screws and the connector has 6 wires that are dark blue with various color traces. The part is about $15-$25. Good luck, James

Mine cost $ 60.00for the part I have the automatic temp control the manual control only cost $20 It is real easy to replace , it is behind the glove box ALSO CHECK YOUR CABIN AIR FILTER IT IS below and to the driver side of the blower resister pack you will need to take off the cover on the bottom of the filter housing. this filter has a cut in in it half wayup the filter so you can install it you will see it when the old one comes out If this filter is not bad check the blower motor it could be going bad Something caused the blower resistor to go bad good luck
