You will need a screwdriver.
Before starting work: Disconnect the wire from the terminal "–" battery.
Replacement of switches and their lamps is shown on the example of the heated rear window switch. This operation is similar for other switches installed on the instrument panel.
The switches for heating the rear window and rear fog lamp, installed on the instrument panel, have built-in indicator lamps, which are located in the upper arms of the switch keys (shown by arrows).
In the key switches installed on the instrument panel, baseless lamps of the A12-1.2 type are used.
1. Press the switch block on the back of the instrument panel with your hand.
2. Remove the switch from the hole in the instrument panel and disconnect the block with wires from it.
3. To replace the control lamp, remove the key from the switch (if you can't do it by hand, then carefully use a screwdriver).
4. Remove the test lamp from the switch holder.
5. Install a new lamp in the switch holder, assemble the switch, connect the block with wires to it and install it in place.
