I have just bought a 2005 GT, but the cruise control seems to be very intermitent.
I have read loads of threads now, and nothing really seems to be answering it.
Basicaly, when i trun the system on, the light on the dash board sometimes illuminates. i cant seem to replicate the error however so im really stuggling.
I have just done what Nugget69 suggested, and i was able to pull out the switch on the clutch lever, but this hasnt sorted the interminent part.
Im not really sure where to post this, but i assume that the cruise control system is smilar in all these models. (i dont know, ive just come from a 97 spider so am trying to learn!)
One time in your life you should have a daft, impractical 2-seater convertible...
