while looking up stuff for 96TL i stumbled upon this.
our climate control unit has a self diagnosis function.
turn the ignition switch ON (II), then press both the AUTO and OFF buttons at the same time. while the buttons are pressed, indicator lights A, B, C, D, E and F respectively will come on to indicate a faulty component
these indicators are basically the fan sppeds
there are five bars that indicate the fan speeds, let's just call them bar 1-5 from left to right.
A: bars 1,2,and 5 are lit up. problem with that is the in car temperature sensor.
B: bars 1,3, 5 are lit up. outside air temperaure sensor
C: bars 1, 4, 5. sunlight sensor
D: an arrow that shows that air is coming from the feet vents. evaporator temperature sensor is messed up.
E: ON. air mix control motor
F: OFF. Blower motor.
In case of multiple problems, the respective indicator lights will come on. If indicator lights a,b,c,d, and e comes on at the same time, there may be an open in the common ground wire of the sensors.
Resetting the self diagnosis function.
turning the ignition switch OFF will cancen the self diagnosis function.
