Key Features

• Black plastic construction for a factory-style appearance
• Push-on mounting for direct knob replacement
• Standard replacement part engineered to match original fit and function
• Non-illuminated design for vehicles equipped with a non-lit control knob
• Compatible with HVAC control functions on specified Ford and Mercury applications

Detailed Description

Dorman 76904 is an HVAC heater control knob made to replace the original control knob on select vehicles without changing the look or operation of the instrument panel controls. The black finish blends with the factory dash layout, while the push-on design supports a direct installation on the existing control shaft. This part is a practical choice for restoring heater and air conditioning control on vehicles where the original knob has become loose, damaged, or no longer turns properly.

This part cross-references Ford (e.g., E5TZ11666A) for the same application.

What It Helps Fix

• Broken or cracked HVAC control knob
• Loose knob that no longer stays attached to the control shaft
• Worn markings or damaged exterior on the heater control knob
• Difficulty adjusting temperature, fan speed, or airflow settings through the dash control
• Missing factory-style knob on the instrument panel
