2010-2011 Saab 9-5 Rear HVAC Control: Guide to the Optional Climate Unit (13290374)
This guide covers the specific rear-seat HVAC control unit for the 2010-2011 Saab 9-5, including failure symptoms, replacement, and how to find a working used part.
- This control unit is only for 2010-2011 Saab 9-5 models with the optional rear climate package; check your vehicle before buying.
- The correct part number is 13290374. Verifying this number is essential for compatibility.
- Used OEM parts are the only realistic replacement option, as new parts are extremely rare and aftermarket versions are not made.
- Failure only affects rear passenger comfort and does not disable the primary front HVAC system or affect vehicle drivability.
Part Identification: Is This The Right HVAC Control?
The 2010-2011 Saab 9-5 was available with an optional rear climate control system. This article exclusively covers the control module for that system, part number 13290374. This is NOT the main climate control unit located in the dashboard.
Compatibility Warning: This part only fits 2010-2011 Saab 9-5 models originally equipped with the optional rear heater controls. Before ordering, physically check the back of your vehicle's center console. If you do not see a control panel for the rear passengers, this part will not fit your vehicle.
Most common HVAC issues discussed in forums for the Saab 9-5, such as blend door failures, stepper motor problems, or pixelated main displays, relate to the front Automatic Climate Control (ACC) unit and the main heater box assembly. A failure of this rear module will only affect climate functions for the rear passengers.
Symptoms of a Failing Rear HVAC Control
Since this is a straightforward electronic module, failures are typically clear and isolated to the rear climate functions. You may experience one or more of the following symptoms:
- Unresponsive Buttons: Pressing the fan speed or temperature buttons does nothing.
- No Air from Rear Vents: The control unit fails to activate the blower for the rear passenger area.
- Stuck Temperature or Fan Speed: You are unable to change the temperature or fan speed from its last setting.
- Blank Control Panel: If the unit has illuminated indicators, they may not light up, indicating a total loss of power or internal failure.
Buying a Used 2010-2011 Saab 9-5 Rear HVAC Control
Due to the rarity of the 2010-2011 Saab 9-5 and the demise of the original manufacturer, finding a new OEM replacement for part number 13290374 is highly unlikely. No aftermarket versions are produced. Therefore, a quality used OEM part is the only practical and cost-effective solution.
What to Check Before You Buy:
- Verify the Part Number: The most critical step is to ensure the part you are buying is stamped with GM or Saab part number 13290374.
- Inspect the Faceplate: Look for clear, unworn button graphics. Check for deep scratches or cracks in the plastic housing.
- Test Button Feel: The buttons should press and return smoothly with a positive click. Mushy or stuck buttons suggest internal wear or damage from spills.
- Examine the Electrical Connector: The pins in the rear electrical connector should be straight, clean, and free of any corrosion or green residue. Bent or corroded pins can cause intermittent issues or prevent the unit from working at all.
- Ask About the Donor Vehicle: If possible, inquire about the donor vehicle. A part from a lower-mileage, well-kept car is always preferable.
Cost of Replacement
Pricing can vary based on availability and condition. Here is a general cost estimate:
| Part Type | Estimated Cost |
|---|---|
| New OEM | $250 - $400+ (Extremely rare, likely discontinued) |
| New Aftermarket | Not Available |
| Used OEM | $50 - $150 |
| Shop Labor | $75 - $150 |
Installation Guide (DIY)
Replacing the rear HVAC control is a straightforward job for a DIYer with basic tools. The process involves removing the rear trim of the center console.
Pro Tip: Use plastic trim removal tools to avoid scratching or cracking the console plastics. A set is inexpensive and invaluable for any interior work.
- Access the Unit: The control is located on the back of the center console. You may need to use a plastic trim tool to carefully pry off the surrounding bezel or panel. These panels are typically held in by clips.
- Remove Mounting Screws: Once the trim is off, you will see screws (likely Torx or Phillips head) holding the control module in place. Remove these screws.
- Disconnect the Wiring: Gently pull the module out and locate the electrical connector on the back. Press the release tab on the connector and pull it straight out to disconnect it.
- Install the New Unit: Connect the wiring harness to the replacement module, ensuring it clicks securely into place.
- Test the Function: Before reassembling everything, turn the vehicle's ignition to the 'On' position and test all the buttons on the new control unit. Verify that you can adjust fan speed and that air comes from the rear vents.
- Reassemble: Once you've confirmed it works, reinstall the mounting screws and snap the console trim panel back into place.
Known Issues, TSBs, and Recalls
As of mid-2026, there are no specific Technical Service Bulletins (TSBs) or safety recalls issued by the NHTSA for the rear HVAC control unit on the 2010-2011 Saab 9-5. Major recalls for this vehicle concern the Takata airbag inflators.
Frequently Asked Questions (FAQ)
Is this the same as the main climate control in the dashboard?
No. This is a secondary, optional control unit for rear passengers only. It is located on the back of the center console. Problems with front air conditioning, heating, or defrost are related to the main ACC unit in the dash or the heater box itself.
Does the replacement rear HVAC control need to be programmed?
It is highly unlikely. This type of simple, auxiliary module is typically a plug-and-play component that does not require special programming by a dealer. It should function immediately upon installation.
Can I add this rear climate control to my Saab 9-5 if it didn't come with it?
This is not a practical upgrade. A retrofit would require not only this control unit but also the specific wiring harness, and potentially different ductwork within the console and main heater box, which would be a complex and expensive job.
My rear controls don't work, but the front HVAC is fine. Is this part definitely the problem?
If the front system works correctly but the rear controls are completely dead, this module is the most likely culprit. However, the issue could also be a blown fuse or a wiring problem between the main HVAC system and this rear unit. Always check the fuse panel first before ordering parts.
