Hi Les 
The fact you have a flashing display panel means a fault has been logged in the HVAC module, this may just be low gas pressure on the aircon but there may be other faults aswell.

Have you got a VCDS lite/Vacom lead? you could check this yourself without going to a garage if you get one of these leads click Here

Have you checked for voltage at the blower motor and controller (hedgehog)

Does it do the same for both the front and rear fans? Do other functions work like changing the temperature/outlets? switching between defrost/auto?

yes the same front and rear i put a test lead on the motor fan working ok but the two leads going to the fan are both live no earth tried two other register's the same so must be a short if the two wires on fan are live thanks for your help had the air con regasd 6 months ago

The power to the fan motors are fuse 21 rear fuse 22 front there are also three fuses for the controller, fuse 3, 19, 32. if these are OK check with VCDS lite/Vagcom.
