usdm climate control modes malfunction

[alilvietboi4u]

i have a 95 240sx. cant figure out this problem on the usdm climate control. air just comes out through the front vents only. the only other functioning modes are the fresh air, a/c, and the temperature controls. i replaced the climate control and the motors under the dash but still nothing. anyone have an idea what the problem is? its bugging me because when my windows are fogged up i cant defrost...

You did replace the mode door motor? That's in charge of directing airflow, nothing else would cause the issue you're having.

There must be an object stuck in the door, or the linkage is bent/kinked. I've never seen a problem and it not be electrical, that's weird. Pull the mode door motor off and manually work the linkage, does it move freely or does it bind? Does it move the full range or does it stick partway?

Its not the mode door actuator, i ran the linkage on the blower everything operates like butter, im not getting power at the mode door actuator plug, im assuming that the OP is having the same problem that i am, i guess ts a electrical problem is there a relay or a fuse etc left to check? im still trying to find a FSm wiring diagram that has a good download link haha, if not i guess i have to pull the dash and start chasing wires

zeroyon.com has working links.

ok zeroyon doesn't work, try skylingking.com

same here. i took the motor off and move the doors manually with no problem. i tested the motors on my other s14 and they work. i guess im not getting power to the motors. i also already have the fsm. still cant figure it out.

Were you able to get a copy of the wiring diagram for the mode door actuator?
