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 |
