no blowers, but not FSR

[gellyp]

Hi all, hoping someone can point me in the right direction in sorting my 2011 RR 4.4 autobiography. couple of weeks ago i lost all blowers, so no heat / a/c or demist blowers. All roads led to the FSR. Fitted a replacement (cheap one), still no joy. Followed advice to test systems noted by member (Full Fat Ray) and confirmed blower motors working and stepped voltage from HVAC ECU works. Figured it was a cheap sh** FSR so bought a landrover one and fitted it (which i can do in about 25 mins now!). Still no joy.

Running out of ideas, and thought i would ask before i give it to dealer to have my throat ripped out.

any help appreciated.
