This could be several problems.#1 Check vaccum canister for leaks or no vaccum from engine. #2 Check vaccum switch at controler (made of plastic has a tendency to fale ) which causes doors in dash not to open all the way and you have minimal amount of air coming from vents.#3 Someone put the wrong squirl cage on the motor some have a 3" cage and some have a 4" cage. #4 Debree may have fallen into defroster ducked and is blocking blower motor air flow.
