1990 Mazda 929 AC problems

[nikkormat42]

Sometimes when I start the car, the a/c blower will not come on. I close the car door, and it comes on.

Saturday, it would not come on, and did not come on when I closed the
car door, but it came on before I got home.

I made some phone calls this AM just to get some wisdom on the matter.
One place said it might be the blower motor which is located on the right side (under the glove box.) Supposedly it needs to be not working before they can check it. Another Mazda dealer said it could be a short in the blower motor.

Thanks,
Jon

I would check for a reasonably priced junk yard unit. If it doesn't work tap it with a small hammer if it starts it is the motor. You can also check for voltage when it isn't working.
