Have known for a while that there was something wrong with my heating system. Even if I put the temperature switches to max heat, it only came hot air for a little while then it cooled of again.
Decided to dissamble the heating valve which distributes warm cooling water to the passanger and drivers side. When I opened it I could
immediately see that the rubber sealings where dry and damaged.
A new one at the local MB dealer costs almost 6000 SEK (900$), fortunatly I found a used one from a 300SL -89 and it only costs 460 SEK (70$).
I will put more pictures as soon as I get the new "used one"...

| Upper sealing is damaged on the right and the filter should be attatched to the rubber "diaphragm" |

| Clearly broken.. |

| Due to the broken "diaphragm", cooling water has leaked in to the electrical coils. |
