IT WAS THE RCM! IT WAS THE RCM! Tighe1 told me to check the Traction Control relay contacts (close them) on the RCM, and Eureka! Spoiler able to lower with button and all but ASB/ESP dash lights not on.. Swapped a friend's new RCM and all was perfect..no dash lights, etc. Put his old RCM (no problems) in my Roadster, and all still perfect. Test drive above 70mph, and spoiler up and down as normal.. SO- sending my old RCM to Tighe1 for complete repair, including replacing 4 relays .. Thanks for all the helping replies ..-Saul
