| 1. The chain has to be in the UP switch family way between conclusions 1 and 2, and also between conclusions 3 and 5. |
| 2. The chain has to be in the OFF switch family way between conclusions 1 and 2, and also between conclusions 4 and 5. |
| 3. The chain has to be in the DOWN switch family way between conclusions 1 and 3, and also between conclusions 4 and 5. |
| 4. If results of checks negative, then the switch replace. If the switch is serviceable, then believe a chain between the switch and the electric motor. |
|
5. If from both switches the same window regulator does not work, then remove the panel, include a window regulator and check tension on the switch and the electric motor. |
| 6. If tension is present at the electric motor, then disconnect glass from a window regulator and check freedom of its movement up and down. Check also freedom of movement of a window regulator. If damages are absent and glass moves freely, then replace the electric motor. Otherwise grease details or replace. |
|
7. If tension on the electric motor is absent, then check wires from the switch to the electric motor. If the relay is provided in a chain, then check presence of tension for the relay and its connection with weight.
