I know there have been some previous posts on this subject but most seem to
refer to older models.
I have just bought a 1999 C Class 220cdi estate. The heater blower switch
doesn't want to work when the car is started from cold. After a few miles I
can sometime get it to work by either
a) switching the engine off and on again or,
b) pushing and pulling on the switch itself or,
c) a light tap on the dashboard.
Sometimes it will start by itself after a few miles.
The problem is the methods described above could point to either a faulty
blower switch, faulty blower motor or some sort of electrical fault.
Any suggestions about how I should proceed and how to get to the switch and
motor without trashing the dashboard.
