The 131871 is a Capacity A/C temperature control knob for yard trucks and terminal tractors. This push-on style HVAC dial mounts on the cab climate control panel and adjusts the temperature output of the heating and air conditioning system.
Direct OEM replacement for Capacity truck models. The push-on design simply pulls off the old knob and presses onto the control shaft — no tools required. Replace when the knob is cracked, the markings are worn, or it spins freely without engaging the control shaft.
