Most definitely it's possible. Passenger side blend door actuator motor or gear is broken. Dirt common with '11 and '12 models and the passenger side usually goes first. Remove the glovebox and this assembly is inside to the left. Not hard to replace. The actuator gear is a $2 dealer part and always breaks causing this problem. Motor may be good if it didn't strip internal gears when the actuator gear broke... but it's $35 on Ebay if so. Passenger side is MUCH easier to replace than driver side... but both sides can be done good as new without tearing out the dash. Shouldn't take a good tech more than an hour to fix. Probably looking at $150-$200 including parts to fix by a good cheap independent tech.
