Diagnostics of malfunctions of system of heating and ventilation

Cause of defect

Elimination method

The electric motor of the fan of a heater does not work

The heater electric motor switch is faulty (it is checked by an ohmmeter)

Replace the switch

Are damaged or closed on "mass" of a wire, their tips and sockets are oxidized or put leaky on, the safety lock fused (tension to the electric motor does not move)

Press out plugs, smooth out tips, replace faulty wires, the fused safety lock (having checked the chains protected by it for lack of short circuit)

Wear, lag of brushes of the electric motor, break in an anchor winding, oxidation, wear of a collector (tension to the electric motor moves, but it does not rotate)

Smooth out a collector or replace the electric motor

Short circuit on "mass" of a winding of an anchor (at inclusion the safety lock fuses at once)

Replace the electric motor

The electric motor of the fan of a heater does not work at small speed

The additional resistor fused, its wires are damaged or their tips are put leaky on

Replace the resistor, press out plugs, smooth out tips, replace faulty wires

The heater switch is faulty

Replace the switch

The anchor of the electric motor of the fan of a heater rotates slowly

The collector is polluted or oxidized. Mezhvitkovy short circuit of a winding of an anchor Jamming of a shaft of an anchor in bearings (the safety lock can fuse)

Replace the electric motor

The interior of the car gets warm badly, temperature in salon is not regulated

The heater radiator is faulty

Replace a radiator

Insufficient temperature of cooling liquid

See. "The engine long gets warm up to the working temperature" in the section "Diagnostics of Malfunctions of the Engine and Its Systems", page 239

There is not enough liquid in the cooling system

See. "Falling of level of cooling liquid in a broad tank" in the section "Diagnostics of Malfunctions of the Engine and Its Systems", page 239

Jamming of the crane in a closed position, jamming of gates of cables or break of cables of management, weakening of their fastening

Replace the faulty crane, cables, gates. Reliably fix covers of cables, oil cables engine, adjust drives
