SL320 top and roll bar lights
Well I finally got to the bottom of it. It was the control unit ( N-52 ) for the top. I tried everything but was not having any success so I talked a friend of mine into bringing his '98 SL500 over and we swapped the control units...That was it. His worked fine on my car - all functions - and then I tried mine on his car and it did the same thing as it did on my car. FINALLY!
Do you know if these can be rebuilt or purchased somewhere with a better price than the local MB dealer?
I really want to thank you for your advice.
