The Fonz.. lights come on when I hit the dash on my '88 300E

1988 300E (OE Becker radio)

I spent some time checking prior threads and was out of luck. I kept coming up with solutions referencing fiber optics and red fuses behind the instrument cluster. I think I may just have a loose connection or something. I was wondering if anyone had any experience with this problem with their climate control center:

Lights on the push buttons are half on and half off. When I the right side of the climate control/radio cluster the right side lights go on for the climate control. When I hit the left side the left side lights go on and the tape deck function lights go on (tape deck was DOA when I bought the car)

-Also, on Fastlane, what is the name of the heaterhose that goes from the back of the head (driver's side) into the fire wall?

-Crutchfield sells a wiring harness for the oem radio replacement, has anybody used this harness?


Thanks,

John
