My condenser went out in my air conditioner. Had it replaced and shortly after front vents stopped working some of the time. After diagnostic, we replaced the blower motor and fuse but all front vents still only work intermittently.

When the vents are not working can you still hear the blower motor running? If so, it sounds like a blend door actuator is not working. If not, it sounds like the blower motor relay needs to be replaced here is the location and a guide to help test the relay.
