Hmm. Yours has 4 wires in the 4-pin connector. I only have 3 wires. And my controller is potted, not with the two chunky transistors visible. I bought a replacement blower and that only had a 3-pin connector, but with + and - the opposite way round! And the new one would only run at full blast, not slowly. My controller knob appears to be a 0-500 Ohm resistor ladder. I'm trying to work out how the controller on this actually works and how many different blower/controller variants there are. I'm getting one with a 4-pin connector tomorrow - lets see if that works any better.(My vehicle is the Peugeot expert 1997 van but clearly things are quite similar but not identical. Vehicle debugging is such fun.)
Update: the 4-pin version of the fan worked fine. So the 3 and 4-pin version of the fan appear to have opposite sense of the control voltage, as well as the power sense the oppose way round.
@@xxwookeyI´m still struggling with my 1996 Peugeot 406. The fan only works in the minimal set, if I try to increase the speed, it slows the fan speed. I tried to replace the digital controller (new and old seems to be in working conditions) I noticed this controller sends about 8.3 volts to the pins 1 and 3 (those with thin wires) I suspect it should be sending 8V to 12V to these pins and speeding the fan as voltage increases. The fan controller is new too.
