The switch of a window regulator and condition of contacts on the switch at various provisions of the switch

 

Power windows work only at inclusion of ignition.

Each window regulator has the separate reversive engine. Position of the switch of a window regulator defines polarity of tension given to the engine and sets the direction of rotation of the electric motor. Overload relays are installed on parts of cars in a power-supply circuit of each engine of a window regulator.

For check of operability of the main switch of window regulators located on the driver's door remove the electric socket from the switch and remove the switch from a door.

Using an ohmmeter, check short circuit of contacts of the switch at various provisions of the switch (see rice. The main switch of window regulators and a condition of contacts on the switch at various provisions of the switch).

For check of other door switches стеклоподъ emnik remove the switch and, using an ohmmeter, check short circuit of contacts of the switch at various provisions ях the switch (see rice. The switch of a window regulator and a condition of contacts on the switch at various provisions of the switch).

If switches of window regulators are serviceable, and the window regulator does not work, check giving of tension to the window regulator engine.

If tension arrives to the window regulator engine, and the window regulator does not work, disconnect door glass from a window regulator and, moving glass manually, check ease and smoothness of its movement. If glass moves easily, replace the window regulator engine.
