the heater/AC blower motor on my 95 blazer doesnt seam to blow very hard.When you turn the blower switch to high the blower stops.I have replaced the switch and the motor restaer looks like it is the blower itself has anyone ran into to this.I thought the blower worked or it didnt.Never see one go from low med to I thank High then off

 

The problem is NOT the motor.

Ignition in the RUN position, mode switch in the HEAT position, blower switch in the HIGH position. Disconnect the electrical connector from the blower relay.

In the vehicle harness connector that you just unplugged:
The orange wire and the red wire must both show battery voltage.

Post your results.

 

fixed mine it was the relay and the plug, went to a junk yard got the parts now it works on hi.
