Likely be the control valve however I have replaced mine PLUS the auxiliary heater pump both as my problem is lots of heat in the passenger foot well but hardly any (just lukewarm) for the driver's, been that way ever since I got
this car 6yrs ago......beginning to believe it’s a “feature” of the 2004 model.......
Both valve and pump are easy to diy with minimum special tools, I used small locking pliers and hose pinchers on hoses to prevent coolant loss.
Did a writeup on it either here on the other forum.
good luck

A blend door actuator/motor controls the blend doors (open and close). When the HVAC is changed the actuators open and closes doors to allow air flow. When non-operational they get stuck. It gets more technical but you should get the gist. Below is a pic of one. Our cars have a lot of them. Also it could be the module itself.
