2004 s Passenger side will not heat but has good cooling. I have seen this subject here before but didn't under stand the answer.How do you see the servo motors that move the controls or get to them? Or could it be a fuze, if so which one?

Best to check the system for codes. The blend door servo motor operation can be viewed if you remove the lower passenger side trim panel, laying on your back look up towards centre of the climate control air box and operate the temp control for that side. You should be able to see the servo motor turn the bend door axle but it is very difficult to see.

A failing servo motor is often associated with noise from the gear drive within the motor.

Problem fixed , I hit a large truck tire tread doing about 60mph on the freeway. Then heard the mixer valve making a noise, turned the heat setting for the right side to 80 deg. Low and behold out came warm air. Now can anyone explain that?
