Operation
There are two diagrams, i.e. one for the 1984 models and the other for the 1985 and 1986 models. They show the supply to the switches, etc. on cars with built-in lamps.

Rheostats 16 and 17 are supplied when light switch 10 is in position 1 or 2, via the 29-pole red connector 152B and fuse 18 (the same fuse that supplies the parking lights on the right-hand side of the car).

Rheostat 16
The brightness of instrument lighting 18 can be steplessly adjusted by means of rheostat 16 in combined instrument 47

Rheostat 17
In addition, the following instrument lighting can be controlled by means of rheostat 17:

Switches and lighting on the centre console
91 Gear indicating light (cars with automatic transmission)
162 Switch for driver's door electric window regulator
163 Switch for co-driver's door electric window regulator

Fault-tracing hints
The supply to the lighting for the controls is live when the light switch is in position 1.

1. Check fuse 18 and check that the supply to it is live.
2. Check that the input and output of rheostat 17 are live.
3. Check the bulbs and check that the supply to them is live.
4. Check the connectors, cable harnesses and earth connections.
