I understand the bad battery being a possible cause of wing up but in this case it is a new 74ah Bosch. I have also checked the wiring to the spoiler motor for power which is ok and cleaned all its connections. The rocker switch on the dash has no effect on the wing but blinks consistently. The RCM is also new and having checked, the relays work as they should. I have changed the ABS module for another s/h unit but have not re programmed with my VIN, does anybody know if this is necessary?
