Air conditioner will not come on

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 RX350. If the AC and heater don't respond when you press the controls, it might point to an issue with the climate control system's power supply. Start by checking the fuses and relays associated with the AC and heater. A blown fuse can prevent the system from turning on. Another possibility is a failure in the control panel or climate control module, which could explain why pressing buttons has no effect. Additionally, the blower motor or its resistor might have failed, stopping the system from circulating air. Diagnosing these components can help pinpoint the issue quickly and get your climate control working again. 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.
