Interior heater controller

[alexcurtis]

Hi all

So next issue, unfortunately I was a little ham fisted when taking the interior heater controls out from my 1999 Griff when I was disassembling and managed to break come of the connections on the pcb as did not realise and could not find out how it was attached :-(

So i have tried to rebuild and solder some of the connections but so far failed… The main issue is that the fan does not work when the pcb is connected ( it runs flat out if not fitted though!)

Does anyone have a circuit diagram of the PCB to help me understand where the issue is please? I can solder as needed not well but well enough…Also does anyone know of someone who can help mend fix the controller? The main issue are the electrical controllers for the fan / heater etc.

My last resort is buying a new PCB from a breaker but that is expensive and would grate a lot having to give in....

Thanks in advance, al

Bump any ideas?

Have you broken the pin(s) out of the PCB?

If so then the likely problem is that the PCB will likely be multi layer and you have broken tracks on the inner layer(s). If so then only some serious open heart surgery under a microscope will stand any chance of fixing the problem.

I have my Chim one here which looks to be just a double side PCB.
Not sure if they are the same but if they are I can tell you which of the ribbon lines connect to which components.

Hi Steve that would be great I will take a photo tomorrow and post it if that's ok , the one I really need is the switch which controls the fan speed (cleft and right rotation) and switches it on/off (push down) I can and already have run a couple of wires where the PCB tracks have failed so may need to run a few more...

Hi
Afraid I'm not going to be any help. I thought you were referring to the Black box type control as used on the Chim and that was what I looked at and reported on.

Best of luck
