SOURCE: 2007 Chevy Uplander Rear Overhead A/C Vents Won't Work

Have you checked the Aux switch near the bottom of the center control console.
There should be a knob with: Aux, Off, 1, 2, 3. This is the switch for the rear AC blower.
If the driver wants to control the rear AC, use the 1, 2, 3 settings.
If you put it on Aux, Than the rear AC is controlled by the passenger in the back seat using the extra controls located on the Overhead DVD player. (The front AC must be on the rear to work)

SOURCE: getting an error code of PO449 for a check engine

You are right. You need the vent valve not the purge valve. The vent valve is a dealer item. Also this is a common problem and GM has released a bulletin on this that involves moving the location of the valve and running some new lines. It comes as a kit from GM, and it costs about a 100 bucks.

The first thing I would check is the fuel cap. Your vehicle uses a closed vent system to control the fuel vapors in the tank and then vent the vapors to the engine intake system to burn. so you have a leak either your purge/ vent solenoid is stuck or open all the time not allowing the on board diagnostics to run the test or you may a bad fuel cap, and it is venting to the atmosphere allowing the gross leak. The purge/ vent valve is under the vehicle next to the charcoal canister.

DTC P0449 Evaporative Emission (EVAP) Vent Solenoid Control Circuit.
Circuit Description
An ignition voltage is supplied to the evaporative emission (EVAP) canister vent solenoid valve. The control module grounds the EVAP canister vent solenoid valve control circuit to close the valve by means of an internal switch called a driver. The scan tool displays the commanded state of the EVAP canister vent solenoid valve as ON or OFF. The control module monitors the status of the driver. If the control module detects an incorrect voltage for the commanded state of the driver, this DTC sets.

What does code po449 mean for my 2007 Chevy Uplander?

EVAP Canister vent solenoid valve- It's located probably back by the gas tank. A small solenoid valve that has power with key on. Pull the connector to it-one terminal will have (I think) an orange wire that should have battery voltage with key in run. If not, check your emissions fuse under the hood.
You may have to drop down the canister to get to the solenoid (very easy-like 3 bolts). There is a trouble tree that shops follow, but it is complicated. You may want a shop or dealer to do it, or you could try a new solenoid,, but that is iffy. First check that there is battery voltage to the solenoid. One is a power wire, the other goes to the pcm for internally grounding the circuit and turning the solenoid on. Sorry can't help more.

There are two. One is the Canister Vent Solenoid located above the gas tank and it has to be dropped to change. The other is the Vent Purge Valve and it is located under the hood to the right on the intake manifold close to your brake fluid reservoir.
