Ac fan not working sometimes

Hey Jerw12345,

It sounds like the blower motor itself has gone bad, here is an example on how to replace and test it.

When it is not working if you hit a bump does it start up again? This is a classic blower motor failure symptom.

Please let us know how it goes.

Are you talking about the blower motor? If so, did you check good voltage and ground at the blower motor connector when problem is ongoing? If good voltage and ground with no blower action, suspect the blower motor. Sometimes those small motor brushes will wear down, if that happens, a vibration or bump may reset the brushes, momentarily, and the motor runs for a bit, then same old problem.

Hi Ken, didn't see you, have a good day.

No problem the more input the merrier :-)
