ACDelco GM Original Equipment HVAC Heater Blend Door Actuators are electric motors that receive a signal or command from the HVAC controller and either open or close the heater blend door, which determines the temperature of the airflow through the HVAC vents. These original equipment HVAC heater blend door actuators are GM-recommended replacements for your vehicle's original components and have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors. ?
| Good Maintenance Practices - Section 1 - Bullet 1 | Musty smell when the air conditioning or heating system is activated |
| Good Maintenance Practices - Section 1 - Bullet 2 | Inadequate cooling or heating temperatures when using the air conditioning or heating system |
| Good Maintenance Practices - Section 1 - Bullet 3 | The vehicle's temperature gauge indicates a 'red' condition |
| Good Maintenance Practices - Section 1 - Bullet 4 | Steam coming from the engine compartment |
| Good Maintenance Practices - Section 1 - Bullet 5 | Unusual smells inside or outside the vehicle |
| Good Maintenance Practices - Section 1 - Header | Your vehicle's air conditioning (A/C) system should be routinely checked by a professional technician. This should occur approximately every 12 months, though you should check your owner's manual for more specific recommendations. Any related maintenance should be handled only by professionals. If you notice any of the following conditions, have your vehicle checked right away: |
| Good Maintenance Practices - Section 2 - Header | Your A/C system requires proper air flow to operate effectively. Poor air flow across the condenser will impact system performance and can increase refrigerant system pressure. Make sure air flow into your system is not obstructed by bugs, leaves, dirt, or other contaminates in between tune ups. |
| Signs of Wear & Troubleshooting - Section 1 - Bullet 1 | Seal failures |
| Signs of Wear & Troubleshooting - Section 1 - Bullet 2 | Damaged components |
| Signs of Wear & Troubleshooting - Section 1 - Bullet 3 | Worn or damaged compressor shaft seal |
| Signs of Wear & Troubleshooting - Section 1 - Bullet 4 | Worn or damaged evaporator |
| Signs of Wear & Troubleshooting - Section 1 - Bullet 5 | Worn or damaged condenser |
| Signs of Wear & Troubleshooting - Section 1 - Bullet 6 | Worn or damaged compressor Seals |
| Signs of Wear & Troubleshooting - Section 1 - Bullet 7 | A/C system component corrosion |
| Signs of Wear & Troubleshooting - Section 1 - Header | Signs of wear for HVAC electrical components include but are not limited to: |
| Signs of Wear & Troubleshooting - Section 2 - Bullet 1 | Use a leak detection dye, such as ACDelco Fluorescent Tracer Dye. Be sure to use the dye that is specified for use with your systems oil and refrigerant type. |
| Signs of Wear & Troubleshooting - Section 2 - Bullet 2 | Look for dirt or containment build up around hose or line connections. This could be a sign that oil, which would attract and hold contaminants, is leaking out of the connection. |
| Signs of Wear & Troubleshooting - Section 2 - Header | To check your A/C system for leaks: |
| Signs of Wear & Troubleshooting - Section 3 - Bullet 1 | Set the climate control system to 'Heat' or 'Vent' |
| Signs of Wear & Troubleshooting - Section 3 - Bullet 2 | Set the blower fan on 'High' (roll down your windows if the interior becomes too warm) |
| Signs of Wear & Troubleshooting - Section 3 - Bullet 3 | Allow more distance between your vehicle and the one in front of you; this enables more air to enter the radiator easily |
| Signs of Wear & Troubleshooting - Section 3 - Header | If your engine begins overheating while driving in heavy traffic, the following steps can help alleviate the condition: |
| Terminal Gender | Male |
| Terminal Quantity | 6 |
| Terminal Type | Pin |
