Please see my earlier post. I really need to do a video of it.Labour ..... £ / $ 148.40 ???? Cheating Swindling Bastards. I Did it myself in UK. Second Hand switch £30. Time taken to change switch - 5 mins.
No need to reset Car Brain, No need to disconnect battery...... Just change the switch and it works. I did mine 4-5 months ago with battery still connected - and it works perfect. Nil Car Brain problems.
