Hi all. Having recently bought my car it's been riddled with electrical bugs. Yesterday, on picking it up from the dealer i bought it from (a three hour drive from my house) i found the spoiler was stuck in the upright position.
It went in originally to fix a broken heater fan and an engine coolant warning light. These are now good but i'm lumbered with more problems.
I'm at pains to take it back and hope it's just a fuse or something.

In detail, the spoiler was down when i picked it up and raised when i hit 60 (i didn't need to check the rear window heater and it's 4 degrees c here so the roof stayed up). A few miles on I hit traffic and noticed it didn't go back down.

The button has no effect, there's no light. When i later tried the roof and rear window it's the same story - no beep, no led light, totally dead.

Everything else appears to work fine so it seems like something has been dislodged. The fact they are all crossfire specific parts (not borrowed from mercedes) and are all located and the back of the car can't be a coincidence, surely?
I'm on a very old phone so my apologies if this has been covered before but searching the net is not easy with a screen this small.

Thanks, Morgan.
