Yes, that code does refer to the humidity sensor on the windshield. I believe the humidity sensor is shown in your first picture. However, what is shown in your pictures looks different than what's in our van and what is illustrated in All Data (pictures below). The components in your van appear to be oriented in the opposite manner (sensor to left of the mirror instead of the right). This is probably because your van is equipped with Advanced SafetyTec (ours isn't). All Data says the humidity sensor is located to the right of the rearview mirror (as it is in our van), but doesn't make any distinction between models with or without Advanced SafetyTec. I suspect this is simply an oversight.
The numbers simply point out items as they are mentioned in the instructions. Removing the cover looks pretty straightforward. I've posted the instructions below. All Data says the part number for the humidity sensor is 68440808AA. Online parts diagrams show the same part number so I'm assuming all vans use the same part regardless of whether or not they're equipped with Advanced SafetyTec.
REMOVAL
- Disconnect and isolate the negative battery cable. If equipped with an Intelligent Battery Sensor (IBS), disconnect the IBS connector first before disconnecting the negative battery cable.
CAUTION: Use care when removing the humidity sensor cover. The humidity sensor bracket cannot be serviced separately from the windshield. If the sensor bracket becomes damaged, the windshield will need to be replaced.
- (Cover removal - refer to Figure 1.) Carefully disengage the four retaining tabs (2 and 4) that secure the cover (3) to the humidity sensor bracket (1) by pressing in on the right side of the cover, while rocking the left side of the cover off the bracket.

CAUTION: Use care when removing the humidity sensor. The humidity sensor bracket cannot be serviced separately from the windshield. If the sensor bracket becomes damaged, the windshield will need to be replaced.
- (Humidity sensor removal - refer to Figure 2.) Using a small screwdriver or similar tool, carefully disengage the metal retaining clip (3) from the sensor bracket (2) and remove the humidity sensor (4) and the clip as an assembly.
- Disconnect the wire harness connector (1) from the humidity sensor.
- If the humidity sensor bracket is damaged and cannot be reused, replace the windshield.

INSTALLATION
- (Humidity sensor installation - refer to Figure 2.) If the humidity sensor bracket (1) is damaged and cannot be reused, install a new windshield.
- Connect the wire harness connector (1) to the humidity sensor (4).
CAUTION: Use care when installing the humidity sensor. The humidity sensor bracket cannot be serviced separately from the windshield. If the sensor bracket becomes damaged, the windshield will need to be replaced.
- Position the humidity sensor to the sensor bracket (2) and engage the metal retaining clip (3) to the bracket. Make sure both sides of the retaining clip are fully engaged to the bracket.
CAUTION: Use care when install the humidity sensor cover. The humidity sensor bracket cannot be serviced separately from the windshield. If the sensor bracket becomes damaged, the windshield will need to be replaced.
- (Cover installation - refer to Figure 1.) Carefully install the humidity sensor cover (3) onto the sensor bracket (1). Make sure the four retaining tabs (2 and 4) are fully engaged to the bracket.
- Connect the negative battery cable. If equipped with an Intelligent Battery Sensor (IBS), connect the IBS connector to the negative battery cable.
I used a hook tool like this. Place it around the plastic cover right by the tab and pull out and down. Do one side at a time. You barely need to touch the windshield.
I know! I am willing to pay a reasonable labor cost for replacing a $60 to $70 part - and especially since it doesn't involve getting into the engine block or anything like that. But $400 seemed a bit excessive. LOL.Also, $480 for the dealer to replace this sensor???? Its a 10 min job with a $50 part, wtf
P.S. the same dealers want $60 to replace the cabin air filter (that costs about $10-$12 for the part).
