If to connect the socket in the opposite direction, the engine of air mixing control will stop in the position of heating.
Attention: If the engine of air mixing control does not rotate, they remove the electric motor and check whether the flap of air mixing control levers freely moves. If the lever of air mixing control and the flap moves freely, they replace the engine of air mixing control.
- Change the value of resistance between plugs 4 and 6 (value of measurement 6 kOm).
- At measurement of the value of resistance between plugs 3 and 4, the measured value should be approximately 1,2 kOm in the position of heating and 4,8 kOm in the position of cooling.
- At the norm of the stated above points of checking, they remove the autotemperature regulator and check presence of breakage and short circuit of wires between the engine of air mixing control.
