I give up

[joolzb]

I've just fitted my new circuit board for the control panel. It's brand new from TVR, I've put all new LEDs (apart from the triangular ones which are on order) in and it still doesn't work. The fans are on continuously, there's a knocking noise from the passenger footwell, the heater motor will only stop at one position. The only thing that's different is the pots, these aren't the standard ALPS ones but are 10k linear as tested by a chap in Maplins who said they'd be fine. Has any one else had this prob? Any ideas on what to look at/replace next?

If I unplug the board the controls won't work. I think the heater control is stuck open so it pumps out hot air. That's what I'm trying to stop. Also the fans won't work which I'm trying to get going in this hot weather.
