HVAC Control Units

Genuine OEM HVAC Control Units

A failed HVAC control unit can leave the cab with no temperature control, a stuck fan speed, or a climate system that won't respond to any input — making long hauls uncomfortable and in extreme temperatures, genuinely unsafe. Because the control unit is the electronic brain of the cab's heating and cooling system, a wrong or generic replacement often won't communicate correctly with the blower motor, actuators, or compressor. That's why every HVAC control unit in this collection is genuine OEM, matched to the manufacturer's original part number.

What's in this category

FAQ

What does an HVAC control unit do? It's the electronic module that processes driver inputs and controls the cab's heating, ventilation, and air conditioning system — managing blower speed, temperature blend, airflow direction, and compressor engagement.

Signs of a failing HVAC control unit? Buttons or controls that don't respond, a blank or malfunctioning display, fan speed or temperature that won't change, A/C that won't engage, or the system defaulting to one setting and staying there.

Genuine OEM or aftermarket? All parts here are genuine OEM — no generic substitutes.

How do I find the right HVAC control unit? Match the OEM number on your old unit, or check your service manual for the correct reference and vehicle configuration, then search that number above.
