So my blower motor stopped on me. I took out the glove box and wiggled the two wire plug and if started back up. Its loose because it has gotten really hot and loosened up. At least that's my guess. The black wire connector is too wide for the blower motor prong and it broke when trying to bend it in. I'm guessing again from the heat. It was also corroded. Anyway I bought a new on and it came in today. My question is, what would cause this to happen? Is this a common issue? I don't want my new one to end up in the same shape because I didn't get to the root of the problem. Should I remove the blower motor and clean the prongs?
