Manual Description
When the evaporator coil temperature rises above the specification, the intake sensor allows compressor operation. When the pressure of refrigerant in the system increases to an abnormal level [more than 2,990 kPa (30. When a mode door position is selected on the front air control, voltage is applied to one circuit of the mode door motor while ground is applied to the other circuit, causing the mode door motor to rotate.
The direction of rotation is determined by which circuit has voltage applied to it, and which one has ground applied to it. Check voltage between front air control harness connector M50 terminal 19 and terminal 20 while pressing the mode switch to the floor ( ) mode. Check continuity between front air control harness connector M50 terminal 19, 20 and ground.
Check continuity between front air control harness connector M50 terminal 19 and terminal 20. Check voltage between front air control harness connector M50 terminal 23 and terminal 3. Check continuity between front air control harness connector M50 terminal 23 and ground.
