It's in the hazard warning switch. You need to replace the switch.
It's a common fault. It failed on me a couple of years back.
To replace it, you need to remove the trim (wood on mine) around it then
pull the switch out and disconnect the connector.
Search www.Audiworld.com forums for how to do it without breaking the trim.
I did !!!!
