Ford F150 no air, no Ac , no heat. No sound of the blower motor.

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your F-150. Since you've already replaced the blower motor, resistor, and fuses, the next thing to consider is the blower motor relay or the HVAC control module. The relay might be faulty, causing intermittent issues with power getting to the blower motor. Another possibility is a wiring issue, like a loose connection or damaged wire, preventing power from reaching the blower motor. If none of these seem to be the issue, the HVAC control module itself could be failing and not sending the correct signals to the blower. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered. Give us a call at 877-913-1554, and we will happily help you out!
