Very likely the regulator. You can try disconnecting the regulator and applying 12V directly to the fan motor to test it.
If the motor is bad, you'll have to find a good used one, or update all of the parts. If the regulator is bad (and you think your motor will keep functioning), you can adapt the a 140 regulator. |

unfortunately you have the dreaded 96/97 210 body.you need to replace both the blower and the regulator.about $800 for parts.

As mattl pointed out there is a retrofit you can perfrom.
My reg gives me problems occasionally, not enough that I am willing to change it at this point. I find turning the ingition off and on again results in the reg working again usually. At some point this will no longer work and I'll be replacing everything.

When the fault occurs my symptoms are the same as prostreethotrod's. I also get a screwy test mode (#9?) voltage reported by the Climate control display when this occurs.
I would rather r&r the ignition switch than do the fan/reg assembly. How/what would one be testing the ignition for?
