A/C blower does not work after a power surge
Which facts are known about that power surge? Lightning stroke, switching activities in the provider's net? If there is a proof of liability, it could be an insurance case.

A voltage surge could have destroyed the surge protectors and/or the related fuses. Power has to be disconnected, line capacitors have to be discharged before any work. The exchange of those most probable soldered parts should be no big issue if some basic electr(on)ic knowledge is available.
