You may have a blower motor that has "dead spots" when it’s winding. Sometimes you can tap on the motor if it doesn’t start to move again. I would try performing this simple tap test and if it starts to move then you know that the motor is defective and will need a replacement.

If you decide to get this fixed, contact a certified mechanic who is capable of properly diagnose your A/C issue and fix it accordingly.
