After never having any electric problems on my 155
apart from blown bulbs, easy fixed, I have encountered my first problem a minor quirk with the internal fan. Engine fan works fine. Problem is with interior fan.
Fan is working fine on full power, no rattles or busses or anything "Speed 4" but fan is not blowing on speeds 1,2 or 3.
Most confused by this.
Is there a separate fan for the lower speeds or some resister box somewhere in the system which controls these lower speeds which needs replaced? There only seems to be one connection to the fan with 2 wires, load and earth, but there are 4 wires coming from switch into loom. I suspect there is a connector behind radio which I dislodged when I put the original radio back in. Been a bit busy recently so I thought I would ask before investigating. Dash has never been apart and I am reluctant to go investigating all over the place when Im sure theres a simple reason for the problem.
Any advice much apreciated.
