- 1st speed - 1 and 2;
- 2nd speed - 1 and 3;
- 3rd speed - 1 and 4;
- 4th speed - 1 and 5.
24. If any contacts do not close, replace the electric fan control unit. To do this, first remove the fan speed switch by pulling it towards you.
25. Using a slotted screwdriver, we squeeze out the latches of the electric fan control unit.
26. Remove the block.
27. Install the parts in reverse order.
