The diaphragm, micro-switch and relay are accessed most easily by removing the glove box.
If the blower engages when the defrost button is pushed then you most likely have a vacuum leak. The usual culprit is the center vent diaphragm.

Ok cool, this is new info I hadn't found yet. Thank you.
I assume you're referring to the little vacuum pods in the dash, right? If one of those had gone bad, would my other vacuum functions still work? Ex, my locks all still work just fine with the key.
Also, are you saying the defroster would work regardless of the vacuum status? Because defrost would be the default in error, correct? If that's the case, I have no defrost at all, so wonder if it's actually an electrical issue.
Lastly, how can I test the three components inside the glove box space?
