Heat blower fan wiring diagram?

[bjarneec]

Hi peeps

Searched a little on this forum and you seems to be the one who can save me

My Heat fan doenst spin - not even at high. There is heat in the air vents, but fan not spinning at all.
Does anyone have a wiring diagram for ll the wires to the heat system, as there is no voltage coming to the controller or fan at all.

Thanks a lot

Hi there, welcome

I have Peugeot wiring diagrams but for the heater they don't seem to be of much use as they don't seem to relate to anything (or even themselves).

Control unit:


8025 - air conditioning control panel
8050 - fan
8045 - control module
BM34 - engine compartment fuse panel/mux unit

Seeing that relay there, here is the relevant part of BM34


L is from the mux controller fuse 18 looks like it's worth investigating (or, failing that, all the fuses)

As I said, I have very little confidence in these diagrams but that's all I have. Hopefully if this gets you nowhere someone else will have a better idea.
