Seems like blend motor works as used with Nanocom....problem probably exists in the HeVAC unit itself....

Thanks for that I will look into it and let you know what I find I didn't think it was the blend motor as I had no book sign

If Nanocom can drive the blend & distribution motors to direct air & control heat, etc. and you get no faults, . . . . then suspect switches on HEVAC front panel rather than the ECU inside. Otherwise it would probably indicate a fault with the handbook symbol. . . . . but that my opinion rather than fact.

Did you try calibrate option in Nanocom ?

That's what I thought Pete no open cheque book symbol on screen and everything works I did calibration twice now still no heat on drivers side will have to see what readings I get when putting the panel through its paces

Nanocom menu should allow you to check all the button responses.
