Why is my AC not blowing in my 2010 Ford F-150 Platinum

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! It sounds like you've already covered some common bases. Nicely done. No A/C equals no fun! If the AC isn't blowing at all, even after checking fuses and relays, replacing the resistor and the blower motor, there could be a few other things to consider. One possibility is a problem with the blower motor resistor wiring harness or the HVAC control module. Sometimes these components can fail or have wiring issues that prevent the blower from receiving power. Another potential culprit could be a faulty HVAC switch or a problem with the climate control panel itself. It's also worth checking if there's any debris or obstruction in the HVAC ducts that might be blocking airflow. Given the steps you've already taken, the next best move would be to have a mechanic perform a thorough electrical diagnosis. They can use specialized tools to pinpoint the exact cause and get your AC blowing cold air again. Good luck! If you have any other questions, please call us at 877-913-1554!
