Got a unit available but no idea if that would cure it.

First place to look has to be the fuse box. I don't have wiring or fuse layout diagrams to hand but I'm sure there will be something in the forum somewhere

Changed hevac with one i know works and still not working no lights also
Tried relay still no joy, i will try the fuse behind glovebox.
Does anyone know if blower or resistor can cause this problem?
Why no lights on hevac.
Thanks for the suggestion up to now

Are you switching the same type of HEVAC or are you upgrading the HEVAC? If upgrading you might have to tell the car you are changing from air conditioning to climate control in the CCF settings, I'm not sure if that would stop it working.

Pete k I haven't been able to check fuse yet, I've swapped hevac from my old disco to new one as it has heated seat buttons for future upgrade to heated seats. Hevac I have installed works as I checked it just before I removed from old car
