Default Half of heat/AC working?

This is a preemptive post. I know my air blows both hot and cold out of the passenger side. None on the driver side in any position. I have been searching and what I can find I prob have a bad blend door?? I can here some crazy noises from behind the dash so it might just be a vacuum line off. Now could someone tell me with certainty where I might find the blend door. I couldnt find anything on k5s just on s10 blazers. I am going to try and tackle this one in the snow tomorrow so I can drive this battle tank around with a clear windshield. If I could just make it stuck on defrost I would be ok with that for now.

I would assume it's a bad blend door, It normally involves tearing the whole dash apart.

I couldn't tell you for sure as I don't own a 5k but have you tried Google searching it or looking it up in a Chilton manual?

I dont think its your vacuum line, then it would just be defrost, vent, or floor but not just the passenger side.

I would guess if its just one side the vents are misaligned or clogged. Yout have to remove the dash and all, which really isnt that bad. On mine the plastic parts seem to have shrunk/changed shape over the years so I had to use some duct tape to make sure all the parts were secure and didnt leak.

After further inspection today I can hear it cycle back and forth between the settings so I am guessing its not the blend door. It doesnt seem that air is blowing out of the dash through any cracks so maybe its plugged and just diverting it all through the passenger side. This is gonna have to be put off until its not -10 outside. I have searched online but came seem to find anything.
