I would suggest stopping by an AutoZOne or O'Reilly's and "borrow" their Scan Tool to erase any codes.
TO reset the "Change Oil" light, turn the ignition to ON (do NOT start the car). Press the accelerator pedal all the way down (then release) to the floor 3 times in less than 5 seconds. Change Oil light should flash then go off. If not, try it again. The trick is to get this done in 5 seconds ro less.

Go to any Autozone and free of charge they will run the code for you, This will tell you "why" the engine light is on. If it's important - fix it or go to shop. If it's something that is minor and doesn't effect the trucks coming and going to next step. Hook up the code reader - again....see if the light comes back on. If it does then ask the Autozone employee if you hold the code reader. There is a "cancel" button to get rid of the code. You can delete the code. The Autozone is not supposed to erase the code. BUT HE CAN LOOK AWAY WHEN YOU DO IT!

It's possible the HVAC needs to recalibrate itself, try the following;
With key on, set all HVAC controls and switches to their OFF or CCW positions. Turn key off, disconnect battery for a few minutes, then reconnect battery. Turn key on, but do not touch any HVAC controls for about 2 - 3 minutes. After that, see if the vents and all other functions work. If this does not solve the problem, either the mode control actuator(s) or mode door(s) are stuck or defective.
