Need Help. AC wont switch on

[Alpinewhite]

Hi All,

My "AC" and "circulate air" wont switch on most of the times (switch light wont glow). What could be the issue.

Thanks

i had a similar problem in my E30. Turned out that the switch have a little floating pin (plastic from memory) which snaps and I replaced it with a small nail which I turned into the same profile. it worked fine but the tolerances must be perfect to avoid a button which only sometimes works.
