Over the past couple of years, I have had the spoiler light flashing problem. (the roof wont go down, or if its down, wont go up)

With a reset the problem went away and only came back every six months or so. Now its back almost all the time. With the light off, everything works 100%, but with the spoiler light flashing, the roof wont go up or down, also the spoiler wont go up or down using the button, but strangely works fine when you drive the car (deploys at 65 mph etc.)

I have tried replacing all the relays, had the ECU tested - no problem found, so now trying to find a garage or dealer who actually KNOWS the crossfires.

I have tried various Mercedes dealers who wont even look at the car as its not a merc, (even though it is under the skin) Also tried the Chrysler dealers, including the new "Fiat" dealers who are supposed to know and support the crossfires. So far I cant find one who can recognise a crossfire let alone fix it!

So does anyone know a REAL crossfire electrical specialist - dealer, garage, independent - anyone who can help (one who actually knows- rather than the sort who just replace things until it works. I can do that!

Ideally in the Guildford, Portsmouth, Basingstoke area..

Its a 2006, convertible.

Help please!!!

 

You need the gifted hands and brain of Pizzaman, friend to owners of roadsters in trouble. Makes house calls in State. PM him.
If you value your life savings stay away from dealers.

 

It's not unknown for a weak battery to cause all sorts of electrical problems! might be worth trying a new battery!
