All the vacuum pipes on the under bonnet manifold are connected ok, there's 5. Through an independent Merc specialist I use, I'm lucky enough to have been introduced to an air-con specialist. He informs me there's another vacuum manifold within the dash (I think he said on top of the heater box) which has many more of these small vacuum pipes attached, so the problem 'may' be there - but it's a bit of a bitch to get at. However, whilst in discussion with him I explained that the LED's within the HAV buttons are always on, this intrigued him somewhat. He suggested (sensibly so) that before we commence dismantling the dashboard, to get at the other manifold, that it's investigated why the HAV LED's are always on as this could be, or indeed point to the problem. As an electronics specialist, and an SL owner, have you ever come across this or have a clue to what the problem may be.
Regards Dale.
