Hi,

All kidding aside, the spoiler uses a high current motor with a transmission. It has 2 relays which control it, both located in the rear Relay Block in the trunk. Relay #3 is the Spoiler Extension Relay and Relay #9 is the Spoiler Retraction Relay. You read the Relay Block L-R 1-6 top row, 7-12 bottom row. The fuse for this circuit is D7.

I suspect your switch or the relays are your problem. Try swapping the relays to see if you can get the problem to reverse itself. This will confirm that the Extension Relay is the problem. You can also remove the switch and jump it, but this is a little more complicated, so try swapping the relays (or just reseating them) first. Relays do tire when about to go, so the extension relay may have bad contacts which release when it gets warm from use. Hope this helps...

Happy Motoring!... Jim'99
