Hi Everyone. I'm a new user and I'm looking for some help if possible. I've got a 2013 maxi none A/C which I've recently installed an A/C heater unit along with a full Touran dash from a donor I have. The fan speed adjuster seems to be working fine however the temperature control and flap position are not along with the backlight on the control panel itself.
It seems to be popping a fuse every time I connect the 8 pin connector.
I've used the heater loom from the Touran and was thinking this was just a plug and play thing as regards the standard heating with a few additional bits and pieces needed for the A/C.
Any help would be appreciated.
Thanks
A/C Upgrade

Re: A/C Upgrade
The heater control panels between the non A/C, the climatic and the climatronic are all wired differently.
Assuming of course that you’re using the control panel from the donor vehicle, you’ll need to grab yourself a wiring diagram for both your existing van and the donor vehicle, compare them, identify the wires and then repin the one in your van to match the donor vehicle.
From memory the A/C control panel will now need 2 canbus wires installing as well as the repinning.
