I replaced a defective blower motor and lost air flow. The blower motor has all 4 speeds, so I am assuming that the resistor is good. All of the blend doors seem to be working correctly, and the heat / cool door is working. I have tried 3 different blower motors with the same results. When turned to high speed, the blower motor it is like what low speed was on the original motor. What could the problem be?

does the car have a cabin air filter? if so it may be clogged reducing air flow

yes there vehicle does have a cabin airflow filter. and if they are looking for it they will find it on the passanger side of the vehicle after the upper cowl is removed by removing the 4 metal clamps holding it to the bottom cowel and the pulling up gently and popping out the several hold down clamps
