Sounds like your vent door is stuck in one position. Either a faulty door motor or loose vacuum line under dash. The Climate control units can have issues as well but won[t know till you have a look. Often the vent flaps/motors are difficult to access when your dealing with things buried in the dash. I'd have a look at the blower motor area first. Sometimes with air flow issues there are obstructions actually in the blower venting such as leaves. Might be a good time to have a look at the in cabin filter if you have one, doubt that's the issue but they need swapped out from time to time. That's all the ideas for now...Good Luck!

I will check these out I appreciate it cuz I'm getting AC and heat from defrost vents but none from my AC vents but once in awhile it will open in blow and then it a quit and then go back to the top.
