The AC/heater blower motor was working the other morning on our way home we went over a set of railroad tracks and it just stopped working. within the last week or so it's been kicking off kicking on every time we hit a bump and then all of a sudden now it doesn't work. I'm afraid that I might have to change the blower motor is there any other options that aren't too expensive that it could be?

Hello,

It is possible to have loose wire to the blower motor.
It will be a good idea to check the blower motor harness and make sure it is secured and does not have any corrosion or loose wire(s).

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
