A/C door vacuum motor.

[Buster52]

I may need to replace the vacuum motor on my 1989 Southwind. Can someone please tell me where I can find them?

The service and parts manuals are there.

If you are going to replace the vacuum motor, I would recommend you remove it and take it to NAPA for replacement. With the motor in hand the sales guy should be able to match it perfectly.

Vacuum pumps can be found at any auto supply but I think you are going to find that the a/c door moves from vacuum created by the engine on your Southwind.
