Please don’t hurt me for even asking this. I just acquired a 2007 Roadster Limited with 17k miles. It has the typical rogue, erratic, demon-possessed rear spoiler, which goes up nicely at 62 but won’t retract automatically or otherwise unless car is put thru another ignition cycle.
I have replaced the BCM, performed every known test on a brand new battery, cleaned ground contacts, and added an engine ground. There are no other glitches in the car - everything else is working correctly.
I admit I have not read every post on this, but I have read a lot of them and I don’t believe I ever saw a “final solution” to the problem outside of battery. Issues. Could someone save me some effort and advise how the spoiler issue finally washed out?
