• Hi, I can help. It's called a "Spare Tire Hoist." I found one for you so you would not have to look for one. Here is the link http://www.autopartscheaper.com/BRAND_NEW_GM_CADILLAC_ESCALADE_22_SPARE_TIRE_HOIS_p/19158309.htm?click=2 This one will fit any GM truck from 2000 to present time.
• Not a bad price either. Just $58.95usd.

• If you have any comments you can leave them here and I will respond.
• Hope this helps and thank you for using FixYa.

Rotate the hoist shaft counterclockwise in order to lower the spare tire to the ground. Continue to rotate the shaft until the spare tire can be pulled out from under the vehicle and removed. If the spare tire does not lower to the ground, the secondary latch is engaged causing the tire not to lower.

If the secondary latch is engaged and the cable end is visible, perform the following procedure: 3.1. Tighten the cable by rotating the hoist shaft clockwise until you hear 2 clicks or feel it skip twice. You cannot overtighten the cable. 3.2. Loosen the cable by rotating the hoist shaft counterclockwise 3 or 4 turns. 3.3. If the spare tire can be lowered, repeat steps 1 and 2 to see if the spare tire can be removed. 3.4. If the spare tire cannot be lowered, rotate the hoist shaft counterclockwise until approximately 15 cm (6 in) of cable is exposed. 3.5. Raise and support the vehicle. 3.6. Place a transmission jack, or equivalent, under the spare tire. 3.7. Position the center of the transmission jack under the secondary latch release button at the center of the spare tire. Arrange the arms of the transmission jack so they will support the tire after it has been released. 3.8. Raise the jack until the spare tire stops moving upward and is firmly held in place, releasing the secondary latch. 3.9. Lower the tire. If the spare tire is hanging by the cable, rotate the hoist shaft counterclockwise until the tire is low enough to remove.

U need the special wrench to lower the spare, there is no other way since the cable hoist is under the spare tire.

contact the dealership where you purchased the vehicle

Code po449 is the canister vent valve solenoid error.This is a common problem with these valves because they are under the truck in the rear by the spare tire and they get all the dirt and water and snow,if you live in an area where you get snow.You will find it on the canister under the vehicle by the spare tire.

1. Rotate the hoist shaft counterclockwise until approximately 15 cm (6 in) of cable (1) is exposed.
2. While holding the latch pin (3), fully depress the latch button (2) and release the secondary latch from the hoist assembly. Some side-to-side and/or up-and-down movement may be necessary to disengage the latch mechanism.
3. Continue rotating the hoist shaft counterclockwise in order to lower the hoist the rest of the way.
4. If this does not release the secondary latch, the spare tire hoist will need to be replaced. See the following procedure.

Important: If the spare tire hoist has been fully raised without a spare tire in place, the secondary latch mechanism may have become engaged. If this has occurred the hoist will not lower and the following steps will need to be followed:

The tools are under the second row seats. The hole for the spare tire lowering mech. is above the rear bumper when you lift the tail gate. Put the proper tool down the hole, turn counter clockwise, lowers spare. Reverse to bring up.

The spare is held in place by a cable hoist, the the tool kit for changing tires has the crank to lower the spare. the access hole is through the bumper in most cases, look under the rear bumper u will see the crankin down access easily that way.
