VAZ heater engine characteristics

VAZ heater engine characteristics

Good day, dear readers.
The heater motor did not survive until the end of winter for just a couple of days. The plans were to replace it with a more modern one, but... there you need to change the box itself, so I wanted to do this in the summer. And here is such a surprise, but there is no money or free time. So I decided to try the VAZ-2101-07,1111,2121 heater motor with a bearing, fan, and KZAE nut. Article: ME255-05. It seems to be modernized, it should work more quietly. And also to improve the system I purchased a VAZ-1118 heater switch. Article: 33.3769. and Additional resistance VAZ-2110,2114,2115 SOATE heater. Article: 2110-8118022. so that operating modes can be used more widely.

In general, the procedure for replacing the motor is not difficult, but without the Russian obscenity, most likely nothing will work.

Next, remove the air duct. Disconnect the wires and remove the box with the motor.

The new motor is in place.

Next we assemble in reverse order.

The connection diagram for the new switch and resistance is also simple.

Thanks to this scheme, we get 2 additional speeds on the motor, which, by the way, are sorely lacking. One is slower than the first, very necessary when it’s already warm in the cabin, but the windows are still fogging up, a small flow is really missing. And the average between the former 1 and 2, which by the way is also not bad, because at maximum it blows everything out of the cabin, as if there was a vacuum overboard
