Hello and Welcome,
My name is MIKE.
The most common fault with these is water getting into the electrics = check up under the drivers side dash... looking for water ingress. If water has got into the electrics module there - you will need to fully dry it out and try again.
If its not that - the switch itself is your main suspect but you should check the wiring first.
Let me know how you go..and / or let me know if you need anything further on this..~~~>>>>>>~ Meanwhile - Please do click on the "Exc / Ok rating" for me at this time.. Thank you in advance for that . ..Note that you can get back to me anytime at all after doing the rating - it doesn't close you out -- Best Rgds, MIKE.
