All,

Recently I replaced my AC blower motor. The new one sounds like it is
working it's little coils off, but I am not getting much air-flow (High
speed give low speed air flow). I have verified the vacuum system is
working properly in sending the air where it is needed, I just can't
figure out if there is another area I should look? Is there another
deflector that may be blocking the airflow or could the motor possibly
be installed in the wrong direction? I installed it with the wiring
connections i the same place as the old one, and nothing scrapes.

Oh, yea. It is an 89 300E.

Thanks,

Thom

Sounds like it is running backward. I used to see this a lot on some Ford
products when the motors were replaced with cheap aftermarket motors. Both
wires were black and people would hook them up backwards. The motors ran
fine, just not much air flow.

Hmpf.. I never thought about the wires being crossed, I thought I
might have placed it in there backwards, since it is pretty evenly
spaced on either side.

This was an aftermarket fan, but it was by no means cheap. I'll give
the wire swap a try.

Thanks
