Hi all
My fans not working so I have removed the fan and tested it with 12v direct and worked fine.
The wire to the fan has 3.9v from the resistor.
Other than changing the resistor any ideas ?

Re: Heater blower fan
Could you post the VIN number for the car, so we get the correct wiring diagram?

VF7**************[VIN obfuscated, can be read by forum staff]
Progress update,
so i have changed the resistor from GSF at a cost of £40,
this one is getting 12v and its got 14v out the other end, the old one had 12in and 3out.
still didnt work!! but i touched the heatsink on bodywork and it came to life.
chased the earth wire back and its brown and melted at the plug near the fuse box (internal).
i have spliced a wire each side (only a thin one) just to see if it would work.
i get continuity now from the earth to steel bar behind dash but its still not blowing.
i tested fan on 12v battery and it worked.
guessing i need to replace the whole cable?

Re: Heater blower fan
ALL FIXED!!!!!!!
put my old "broken" controller in and it worked fine after repairing the earth.
for anyone who iss interested, if you remove the glovebox there is a black connector with a brown and earth colour wire (green and yellow), this is on the left hand side of the glovebox to the right of the spaghetti of wires.
this for me is what was burnt out so i cut the earth either side (never at the connector , give some extra just incase). and spliced together and worked a treat.

Re: Heater blower fan
Hi Sean. This sounds remarkably like the problem that i am experiencing. Trouble is I can’t get the glove box out. Taken all the screws out around the edge, took the plug out the back, one on the left hand side beside the side panel. Help! Any guidance you can give me would be greatly appreciated!

Re: Heater blower fan
Hi, I found there is 3 screws at top, 3 at bottom.
There is a plastic cover which is the side of the glovebox, it’s almost part of the dashboard.
The bottom where the little light is, there is some push studs, pop the middle out and they will come out. I had to use some force to get the box out but the wire to the light inside the glovebox isn’t that long. Once it’s out just pop it out.

This photo is the wire which was burnt out, see the discolouration.
