The climate control on my 300SD is completely nonfunctional.
No fan, heat, air - no nothin'
I've checked the fuses in the fuse box and everything is OK.
I've searched previous posts - and while there seems nothing that addresses my specific problem - there have been
suggestions that the ignition switch may be at fault.
I've inserted the key - and as suggested "jiggled" the key at different radial locations of the keypath - and still nothin' !

Can anybody offer any assistance in troublshooting this problem ?

Thank you
