Without 'year make model', it is all guesswork. All questions need 'year make model' as the first 3 words.
Then there are over 40,000 categories to choose from listed by 'make year model'.

Not sure if you are talking about the AC Blend Doors or the airbag system. Everything can be answered via Google

year make model (the question)

When replacing the dash you probably missed a connector or have one that is badly seated.

No.. If air bag light is on, it means the airbag system is shut down and will NOT deploy in the event of a collission. You will need to have the codes scanned for the airbag system to determine the problem and repair as necessary

Not being too familiar with the Chevy venture apart from being in the vacinity of the radiator somewhere the only other option I would of thought is on the front part of a chassis rail where the bumper bolts to my reason being is that you would not want the airbags to deploy from a slow impact but a more fierce impact when damage could start to crush the front part of the chassis then the airbags would be deployed

Remove the negative cable from your car battery before replacing car air bags. Not removing the negative cable could deploy the replacement air bag, causing injury. More car obd2 scanner to maintain car with cheap price.
Deactivate the air bag by removing the air bag fuses. Look in your car owners manual to locate the fuses.
Unscrew steering column paneling and remove the airbag bolts on the back side of the steering wheel. Pull out the airbag until you see the back side and unplug the wires.
Plug the new airbag into the wires and rebolt it back onto the steering wheel. Replace the car steering column panels.
Replace passenger side air bags through the glove box or main dash panels. Remove the glove box by taking off the glove box straps and undoing the hinges. Unplug and unbolt the airbag, slide it out the front of the dash, slide the new air bag in and rewire and rebolt it.
Put the glove box or dash panels back together. Reconnect the fuses in the fuse panel and the negative cable on the car battery and you're finished.

sounds like the steering colum has collapses slightly. Have a profesional chek it. Did the airbags deploy?

assuming you mean the control module and not the actual bag, then... its under the dash, on the floor, behind the center console

However, this is not something you really want to play without experience since....
static electricity will deploy your bags!!!

In most cases this problem is caused by the rotating ribbon circuit contact under the steering wheel having a broken filament, the part is known as a clock spring contact, u will need to properly disarm the airbag and remove the steering wheel to access the part. WARNING: Failure to disarm the airbag system can result in an unexpected Airbag deployment and possible serious personnel injury disconnect the battery 30 minutes prior to start of work.

***As per Haynes Manual for your Vehicle*** Warning: if your vehicle is equipped with a suplemental inflatable restraint (SIR) system, always disengage airbags before working in the vicinity of the sterring wheel to avoid accidental deployment of airbags.
1. disconnect the negative cable at the battery
2. Remove the steering wheel if it interferes with the access to the steering column covers on your vehicle. Remove the steering column covers.
3. Unplug the wires from the ignition switch, remove bolts and lift the switch off the steering column.
4. Installation os the reverse of removal.

Hope this Helps! I have a an illustration and it looks that the switch is on the left side of the steering column. If you need any information or help removing the Steering wheel or steering column covers let me know! Good Luck.

to disable them,unplug the plugs after the battery has been disconnected for 2 minutes to avoid deployment. if you physically want to remove them,that is different,the one on the passenger side is part of the dash,a thin plastic line ruptures upon deployment and the airbag inflates.
the drivers airbag is disabled by the yellow connector at the bottom of the steering column

try spraying some armor all where wheel meets the column covers
