I have a '99 SLK230. I know how to get the radio out and the dash apart, from some car audio work I have previously done. My problem is a burnt out climate control ring light. I removed the climate control assembly, noted the positions of the two turn knobs and the two nylon fingers that operate the blend doors. I was hoping for an easy bulb replacement but I have been foiled by the MB design engineers. It appears to be a snap together assembly not meant for servicing. I have gently released the fingers holding the two halves together and have all of thess points free but the two halves won't sperate. I am afraid of the "apply brute force and hope for the best" method. What retainer or fastener might I be missing? Any help, photos, instructions or diagrams would be greatly appreciated.

Oh, I did search "climate control" and some variations in the forum before posting but it didn't pull up anything regarding how to change these bulbs, just a few threads about how they seem to burn out often.

Thanks,
Stephen

 

Pull knobs off from the front (Unit still in car)

ive been searching everywhere to find this out, thankyou - if this works I will buy you a pint if we ever meet

 

it worked, many thanks..... tho fat fingers here had a bit of trouble getting the new bulbs back in.... used the same bit of plastic tube in the end but with a screwdriver gently pushing the bulb top .... otherwise whenever I tried to remove the plastic tube it pulled the bulb out again....
thanks again
