Hello together! With my Sprinter *) the following problems have arisen over time: – Heater has failed – the “normal” vehicle heating heats even after turning down still about 10 – 15 minutes further – recently the blower has only failed in the stages 1 and 2. I have now removed the control panel to see if there is possibly a purely mechanical fixation: of course nothing discovered. I wondered about the big board and a lot of threads here g elesen. After some pondering I think it is now possible that above all defects could all be related to a faulty control panel. Before I spend around 400 EUR for a new part, I would like to ask you if you are also most likely to tap on the control panel. Unfortunately, I am a bloody layman, as far as electrical equipment is concerned, therefore: is there a way to narrow down the causes of errors? Thanks already for thinking about it! *) 316 CDI, Bj. 2005 – HH9, HZ9
