Your speed switch located in heater box usually one wire to it in passenger feet area above "TOES" usually you loose 1 or 2 speeds on fan but it is unplugged or completely cooked good luck!

No air in front but i have air in rear is there a belt in front ??


Can you hear the front ac/heater fan? They use the same AC compressor so that should be okay. The fan switches fail quite often on those. That controls how much air is pushed by the fan for AC, heat and defrost. The switch is attached to the fan knob on the dash.

Heater fan not working . changed fuse and nothing Silverado 1500


you can test the motor with a multe tester with ohms capable, locate the heater motor and the wires feeding it there will be 2 find the plug and unplug it, using the tester probe the 2 wires with the red and black from the meter to the motor side, on ohms scale the meter should deflect close to full scale, with a digital it should read around 30 or have at least have a low number but no lower than 20 or so, if you get a reading your motor is probably OK, you can also use the meter in voltage mode and with the heater turned on you should read a voltage higher than 10 on the vehicular side of the plug, if there is no voltage there check to see if you have voltage at the heater fuse, if so than replace your fan control switch,,,good to go

I have a 2005 chevy silverado heater/ac fan stopped working . Checked fuses all were good .Removed fan and it works ,whats next?


Treed55508,

Try this solution. I have had the same issue three times. A Chevy tech told me that if it keeps doing it, to replace the blower motor, as it seems to be a chronic problem with the blower having to much resistance and thus burning out the resistors. I suspect that you probably had lost one speed first and then more. It has happened both ways with me, once the entire thing went out at once and then the other times it goes one speed at a time.
