Hi everyone,
I hope you can help me with my problem,
A few weeks ago my heater fan suddenly stopped working. I checked the fuses and they were fine, so I took it into the garage to get it fixed.
After about an hour of checking they told me that it was a fault with the loom/resistor and that the following would need to be replaced:

1) A new resistor
2) A new loom

And they also said that they had disconnected the loom from the motor due to safety reasons, the loom was getting too hot and the connector had "melted".
And then they told me it would cost £572 pounds to fix it!!!

So I went home and did some reading on the loom etc. and had a look under my glove box. I could see that they had disconnected two connectors, a grey one and a black one (I have attached pictures).
The grey connector seems to have been damaged (possibly the "melting"), but the black one seems absolutely fine.
The grey connector and the black connector both have two thick wires (black + brown) connected to them.

Does anyone know what these connectors are for? I have looked for replacements but the offerings on ebay (see http://www.ebay.co.uk/itm/FIAT-GRANDE-PUNTO-HEATER-FAN-MOTOR-RESISTOR-WIRING-HARNESS-LOOM-PLUG-ACTIVE/121282992232?_trksid=p2054897.c100204.m3164&_trkpa) don't seem to match what I have in my car...

I am comfortable with soldering and electrical work, but it is hard to find documents and wiring diagrams related to my problem.

Any help or advice will be much appreciated! Thanks for your time!

Thanks for the guide, I read it but I am still confused because the connector types and wire combinations shown in the guide are noticeably different to the ones in my car which have been damaged...

I have taken some more pictures and labelled them as follows:


A = Red and Black connector going directly into the motor (I assume this is the power for the motor) with thick wires

B = Green/Blue and Black connector going into motor with thin wires.

C= Brown and red connector going upwards for about 30cm... which then changes colours to Yellow and Grey! With thin wires. It ends up being connected as shown in label G.

D= Brown and black wires (currently disconnected) with a two-terminal grey connector. Thick wires. Seems damaged.

E = Red and black wires (currently disconnected) with a two-terminal black connector. Thick wires. Seems OK.

F= Sockets for connectors types D and E. Don't know which connectors belongs to which socket as this was disconnected by mechanic at garage.

G= Connection for C.

Other information of note is that my car is a 2009 reg and that it has air-conditioning. I have attached a picture of the air-conditioner/ heater control panel.

Any help greatly appreciated. Hopefully someone out there knows. Thanks for reading.

Cheers!

Aw well it looks like I'll have to go to a garage... It's getting pretty cold now and driving with the windows down is bloody freezing

Did you get it fixed? If so how much was it?
