Q:

What needs to be done to make new blower motor work properly? on 1994 GMC Safari

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
the new blower motor burned up the day mechanic installed it (smoke filled van) Replacement is doing the same as the first before it burned, air comes though vent on high speed, then drops off and comes out the heater vent by the floor.

The old motor never did this. I'm afraid to use it, and it's useless blowing on the floor anyway (a/c itself went out over 2 years ago) Can something be done.

Thanks,

If the mechanic doing the work is a licensed business , then hopefully he/she should be able to properly diagnose the cause of the blower motor , and should be diagnosing the cause of the failure instead of just tossing the part in. Diagnosis should not be free , but it should have been done at the time of replacing the second failed motor.
is the new blower motor seized if so take it and get new one if its not seized then will have to check to see if there obstruction causing motor not to turn
