Hello everyone, it has been a long time since I have posted. Glad to be here. I have recently gotten excited about my 1985 300SD again. In doing so I have noticed that the temperature gauge is not working (along with other neglected items). The needle doesn't even budge. Any suggestions on how to remedy this would be very much appreciated. I have searched through multiply threads but haven't found exactly what I am looking for. Thank you in advance.
