Technical Fiat Multipla 2004 Fan Blower Problem

[Abri]

Ok 12v orange wire means you just need a wire with a switch on the black wire to ground to make it work.

You could try a known good working fan speed controller but I expect you are not willing to find and buy one.

Thank you, I would love to try a working speed controller, if I can find one. Ok so if I just run another wire that goes from Ground to the fan, that might then work? But if I put a switch in the Earth wire, and the fan moter gets the 12v all the time as seem the way at the moment, would that then be ok for the fan. As a novice in AC electrical work, you always put the with in the live side not the neutral? Im just asking

Just do what you were told

I will not be posting anymore on this thread.

Try fuse 5 (as depicted in this diagram) on the fuse panel under the floor of the driver's side glove box:

As @jackwhoo says though, the actual locations of the fuse for a given job on the Multipla are notoriously "fluid" . They may not be where they are shown to be and the actual format of the fuse panel may not look like that shown. There are several variations of fuse panel. Sometimes it's easier to remove the suspected fuse and run a continuity check on the socket connections themselves.

As an aside, the 12v power socket (aka cigarette lighter) should be fuse 9 in the above diagram

That's so FIAT...

Yes I know, but I dont know where to find it, I checked every single fuse that I could find and all were ok, so It is very possible that Im not finding the correct one for the Resistor. therefore I thought it might be easier to run a new wire with a fuse in from the Lighter for instance, just to ensure it gets power. My problem is though that I dont know which wire to cut and connect to my direct line

My identical problem was tracked down to the cable loom connector hidden under the centre footwell cover (4 screws).
It had melted, breaking all fan/relay.contacts, without blowing any fuse!)
Cut and rejoined the individual cables. Sorted!

I was thinking the same thing, I am sure I have done this in the past under centre plastic cover.

Other joy I had was someone I am married to, putting a desiccant bag on the dash that collected moisture, then it dripped into the fuse box area as a nasty corrosive liquid. Alarm would randomly go off and all sorts of ghostly things ...
The fuse board was destroyed and short circuited and I need to replace it completely.

Good luck and let us know if you fixed it.
