The hazard and heated rear window switches are supposed to light up with the headlamps.   They often don't.

 

If not...

 

Firstly remove the radio, which means removing the ashtray (pull), then the housing - 2 screws.    You can then unlock the radio cage by operating the fingers above the ashtray.  Pushing outwards and locking them in place.   Pull radio out.      

 

Easiest way to remove the switches is to use a screwdriver.   Firstly you can feel the back of the HRW switch with your fingers.    If you put the blade of the screwdriver against the back of the switch, gentle pressure towards you should pop the HRW switch out of the dashboard.      Repeating the trick but angling screwdriver 25 degrees from vertical should find the Hazard switch.

 

On the side of the switch is a plastic screw - turn through 30 degrees or so and the bulb should withdraw.     The bulb is a 12v 3mm subminiature switch, colloquially known as a 'grain of wheat' bulb.    The metal tails pass through the bulbholder and wrap around the outside and form the contacts.     Each bulb should have a tiny coloured sleeve, like a bulb condom - red for the hazard switch, and both amber and green for the HRW.   The green is the lower bulb and the amber is the upper one.

 

If you want to change the switch for a better one, thats the easiest way of removing without damaging things or taking dashboard out.   There isn't much spare cable, so reconnecting them requires a bit of patience...
