My car is blowing hot air all the time. The little dial to turn from hot to cold on the climate control does nothing. It moves but when i turn it and look under the heater box to where the little motor is that moves the linkage it does not move.

I removed the cable from the motor and the cable moves in and out. I check in the engine bay and the little valve there opens and closes. So I removed the heater motor and hooked it directly to battery power and it moved the linkage, so the motor it self is working.

I plugged it back into the under dash harness and turn the heater dial from hot to cold and nothing happens. So i need a diagram of the heater controls for jdm ef8 sir. I problably have a blown fuse or broken wire somewhere. I also removed my a/c and everything that goes with it including the relays. So maybe for the cold air to work properly I need to hook the a/c wire harness and relays back up.
