I have a 2003 saturn l200 and my heat and air both work and the blower motor works on all speeds but the air only comes out of the defrost. I have been told it's a blend door actuator problem? Where would that be at on my car or what might the problem be? Please help!!!

SOURCE: Blend door not working.

The bleed door controls air temp not where it comes out, dash, floor, defroster, this is most likely a mode control switch problem, that switch is on the ac control head.

check the vacuum supply and vac lines from the control head for a leak

There is a vacuum leak under the hood. On the 4.0 liter it is usually at the intake manifold near the brake booster. The 90 degree vacuum fitting pops off of the nipple of the intake. On the 5.2 liter the vacuum leak is usually near the battery where acid corrodes through the line as it passes near the battery box to the reservoir under the box.

SOURCE: How do you fix the driver side air blend door actuator?

you cannot repair the actuator you need to replace it with new one. These motors turn but get weak with time. if you test it, it works, put it in and it doesn't. this is because the motor is weak, unfortunately GM does not sell these motors separately.

I recently did mine, I hear you can do it without taking the entire dash apart but I had no luck with it myself. I have to get ready for work but, on mine it was located down and to the left of the radio. its a white box...are you hearing a clicking noise or something? I had to roll the entire dash back and it was still a major pain getting it out.
