What info are you expecting to get? The head unit will not display anything relating to the passenger side.

With that said, if you need the wiring and connector info for the passenger side actuator, then I can post that.

Do you know that wiring is damaged? If you think you have an issue but have not verified it, pull the DIC codes and see if you get anything for HVAC.

I can get the connector pin out for you which also has the wire colors. Not at home now but can do it in the morning.

The HVAC unit only allows the passenger to adjust the temperature up or down some with regard to what the driver has selected (and displayed). Fooled me too at first when I got my car.

Curious why the connector pins don't have some wire color showing? If you need to remove the pins in the connector to do your work I can tell you how to release them. It is very easy. You can also buy new pins. I have the Delphi part number also.

Also, if you need to remove the dash pad to allow better access I have that info too. It is not hard and many novice DIY folks have done it.

Here is the pin out.









HVAC Actuator Connectors


Inside air temp sensor is AC Delco 15-72496 or GM 16267411

Your local dealer or GMPartsHouse are good sources. Note, it plugs into a connector with wiring harness. It is just the sensor. If you need the harness also I suggest VetteNuts who is a Forum vendor.

Just in case you missed it earlier, the passenger side temp does NOT display anywhere. The only difference when you turn the passenger **** is a slight change in temp between the driver and passenger vents. NO indication on the display.

I never try to use the Forum search to find info. I use Google and get all the Forum hits and those from other sites too. Most people do what I do.

Glad you got it fixed. I keep several cars at my warehouse and keep varmint poison and traps to prevent what happened to you.
