Which blower motor would that be?
On the dash air? If so, and it works with direct power it is a pretty sure thing the switch is bad. Not that expensive and not hard to replace. Most automotive stores would have one. Mark the leads and take the old one with you. Hope that helps here. Please get back to me if you need more as all follow ups are included in our fee.
Did you check all the fuses? I don't do dash A/C work as a rule so I will opt out and let another tech offer something.
Website, glitch. I was not meant to reply Sorry.
