Need Help. AC wont switch on

Hi All,

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

Thanks
Arun

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.

Fan has to be ON too.. ;)
