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

1. Your climate control could have some broken solders. However, most likely, the lightbulbs on your climate control unit are loose or about to go. To replace, remove the wood cover (2 screws on top of the radio area). You will see a couple of tiny aluminum foil covering a couple of holes. That is were the lightbulbs are. Get a couple of replacement lightbulbs from the dealer. Get a rubber hose the size of the lightbulbs. Use the rubber hose to"hook and remove" the lightbulbs. Do the opposite to install the new ones. Of course there is the pro way to do it, disassembly, removal and replacement of the lightbulbs. I did it the easy way. It works!
2. I bought mine at the dealer. The number is on the hose, though. It is not expensive.
3. I used the harness. Perfect fit. It is free if you buy a car stereo from them.
Good luck!
