Repair and operation of the car

The automatic system of climate control provides with regulation of temperature set by the driver irrespective of external air temperature. The control unit of system obtains information from several sensors to maintain temperature in interior of the car at the required level. The sensor of temperature of cooling liquid is located in a heater casing. The sensor of temperature of the arriving air is located outside of the evaporator. The solar sensor is located on the dashboard from the driver. The sensor of temperature of air is located behind a forward lattice, and the control unit is located in the dashboard (see rice. Arrangement of components of system of climate control).

The system of climate control is equipped with system of self-diagnostics which collects information on malfunctions and will transform them to codes which register in memory of the computer.
