Heater only blowing out front vents, no heat to feet or defrost. Why?

Heater working but only blows out front vents. No heat to feet or defrost. Before replacing Heater Control Unit, it would only blow hot air from front vents- With this replacement it will now change from cold to hot and the air flow pressure does change from the front vents when changing the setting dial but there is still no air at all to feet and defrost. Can anyone tell me if there is a louver or valve that could be jammed and where to locate it? Or what else to try? Thanks!

"@nothotwheels , Most likely a AC/ Heat, blend door actuator problem. Actuator could be stuck, faulty, linkage off, etc. Could not find a link for the 1998-2003 protege but will post a link to show and tell in general where and what to look for. You may also find a reasonably priced repair manual online or at the local library to borrow. Good luck.

I hope this helped you out, if so let me know by pressing the helpful button.

it must be the cable thats hooked up in to that regulator that changes the direction of air
