Manual switch for the rear spoiler doesn't make the spoiler go up. Checked the fuse and it's fine (Row A, Fuse 3). Don't seem to be getting a warning message in the on board computer display. I don't think it goes up at 75MPH either but I need someone to follow me to find out.
I know 986 Boxsters have two relays under the carpet in the left rear. One for up, one for down. If the up relay is bad you can swap them see if you have a bad relay. 987 Boxsters don't seem to have those same two identical relays. One relay (964 615 275 00) seems to be an AC System related relay (Pelican search). The other is a Bosch part number. Not having the electrics manual I can't figure out what it does.
Any suggestions on where to go next in search of fixing the rear spoiler operation?
