Why is my vw t25 heater blower not working?

If little air is coming through the vents (hot or cold) on Your VW T25, then it could be because the blower motor for the fan or a switch or resistor that controls fan speed isn't working. Another cause might be that the electronically controlled blend doors that direct airflow is stuck or broken.A heater blower motor uses a unique squirrel cage design to draw air into a vehicle's climate control system, and force it into the various vents. The blower motor requires a high amount of amperage, controlled by a switch in the climate control center and a blower motor resistor.
