I have a 2006 Convertible with similar top problems. When the temperature is 80 degrees or more the top will not operate, either up or down. The "red" indicator light on the consol blinks on & off whenever the key is turned on. My dealer has replaced an electronic modular but this did not correct the problem. Since then, the dealer as switched 2 relays mounted on the hydraulic power unit. Since then the temperature has not reached the 80's, it is now fall in St. Clairsville, Ohio. I am afraid the problem will return next summer. When a suddon rain storm comes up and the top is down it is not pretty. If anyone has knowledge of this issue, and knows what it takes to correct the problem, please contact me at 330-352-0097, or email lhendershot@aol.com
