Air blend motor replacement
Hi, I cannot find the thread or video that shows how to replace the air blend motor by removing the radio and not messing with the air bag at all. Does anyone have a link to it or am I imagining this really exists?

To properly replace the Blend Door Actuator/Motor and /or its levers, the following procedure should be followed.
This procedure eliminates the breaking of the tabs on the passenger side air bag deployment door and also eliminates the removal of the air bag. Only the top half of the instrument panel needs to be removed.
Also before starting, make sure that you have your radio code.
1. Remove left and right "A" pillar trim panels.
2. Remove upper and lower covers on steering column (3 screws).
3. Remove Instrument Cluster.
4. Remove center section of instrument panel (with plastic pry tools).
5. Remove radio (with keys).
6. Remove glove box
7. Remove defroster vent strip (with plastic pry tools).
8. Remove items, 6-7-9 if so equipped (with plastic pry tools)
9. Remove side panels #128
Start by removing those screws indicated in red.
Pull the ends and the top of the lower portion of the instrument panel slightly away to reveal the two green screws.
The two screws are upward inside that cavity. Feel around inside and locate them by hand or use a small mirror.
Then remove the two screws indicated in green.
Those screws indicated in purple might or might not be there, depending on model year.
Then gently pull away the top portion of the instrument panel, all the time making sure that every screw has been removed.
After installing the new Blend Door Motor and before replacing the Instrument Panel, reattach the A/C-Heater Controller, start the truck and check the workings of the Blend Door in every temperature stage.
On re-installation, it might be easier to fit the upper dash if the end and middle A/C vent were removed. If so, remove them by unlocking them from the back side.
Hopefully I have accounted for everything and good luck.
