Warning! The car models covered in this manual are equipped with an additional security system (SRS). Before doing any work near the airbag unit, steering column or instrument panel, turn off the SRS to avoid injury if it is accidentally deployed (see Section Airbags - general information). SRS circuit wiring is easily identified by the yellow color of the insulation.
Main tempostat activation switch
Examination
1. To check the switch must be removed from the vehicle.
2. Using a probe lamp or equipped with an individual power source, check for continuity between the switch terminals in both of its positions. Replace assembly if necessary.
Replacement
1. Pry off the switch with a small screwdriver and remove it from the instrument panel. Disconnect the electrical connector.
Note. Place a strip of tape on the tip of the screwdriver to prevent damage to the plastic.
2. Disconnect the wiring and remove the switch assembly.
3. Installation is carried out in the reverse order.
Hazard switch
Examination
1. To check, release the switch from the facing of the panel clock assembly.
2. Make sure that the distribution of conductivity between the terminals is correct in both positions of the switch. If necessary, replace the assembly.
Replacement

2. Disconnect the 10-pin connector from the back of the switch. Press the locking tab and release the switch assembly from the clock face panel.
Heated rear window switch
Examination
1. The switch is part of the assembly of the control panel for the functioning of the heater / air conditioner. A description of the procedures for removing and installing the assembly is given in Chapter Cooling, heating systems.
2. Using an ohmmeter or a probe lamp equipped with an independent power source, check for continuity between terminals B4 and B9 of the 22-pin control panel connector. Conductivity should only take place when heating and glass are turned on (switch button recessed). Replace the switch if necessary.
Replacement
1. Remove the screws holding the front and rear sections of the control panel together. When removing the front panel, hold it face up.
Note. Before proceeding with the disassembly of the control panel, prepare a replacement switch, which may have to be ordered from an authorized service station.
2. Remove the old switch and install a new one in its place, then articulate and squeeze the front and rear sections of the heater/air conditioner control panel together. Screw in and tighten the fixing screws.
3. Install the control panel assembly in its original place (see chapter Cooling, heating systems).
