Shop AC controllers for heavy-duty truck HVAC systems at All Pro Truck Parts. The AC controller manages temperature settings, fan speed, and mode selection for your cab climate system — a failed controller can cause erratic temperature swings, inoperative fan speeds, or a completely dead HVAC panel. We carry replacement control units and electronic modules for the most common Class 6 through Class 8 truck platforms.
Visit our help center if you need help finding the right AC controller for your truck.
