    at first the lower ends went, then eventually the high went. we replaced the blower motor but that was not the problem:( there is a some sort of a sending type unit we took out next to the blower it was quite corroded we hope a new one is the cure.

2003 GMC Envoy Heater Fan doesn't always blow


Your problem most likely is the resistor block. In order to limit the fan speed a reistor is placed in the circuit which will limit current flow to the motor thus giving you the diferent speeds. High speed bypasse the resistor to get full motor speed. Since you only get high speed it is very likely that the resistor block is faulty

2003 envoy heater blower does mot work on any speed


The switch on the dash could be defective or look for a module near the heater fan on the fire wall side of the engine dept. Trace the wire attached to the fan motor back to help find the module, check it with your nose to see if it smells burned. You will not mistaken the smell of burned electrical components.

I have a 2003 GMC Envoy with manual heater control. The blower only works on the highest (5) setting.


Most likely the resistor pack has failed. It still works on high because high bypasses the resistor.

2006 slt gmc envoy ac problems vent controls anbd


{: ) The popping sound you heard is caused by the sudden movement of an HVAC door, most probably coming from the recirculation door actuator (right dashboard area) or the mode actuator( mid dashboard area). The fan outputs could be normally working, but is being muffled by the incorrect positioning of the HVAC doors, giving an impression that there is fault in the blower controls. In other words, your vehicle is having an air distribution issue.
If there's no conflict in your climate settings, then the trouble may be in the HVAC doors binding or broken, or the actuators faulty or sticking. In both cases, servicing may involve removal of the dashboard to access these HVAC components.
