The other night i put my top down to give my back windsheild a good cleaning, it was a lot colder than i realized (35 degrees) the trunk tilted backwards, but the top didn't come off, it just hummed a bit, i pushed the top button forward to put the trunk back and put the windows up. the next morning the top worked fine, it was much warmer the next morning (about 60 degress), i remember reading something in the owners manual about never putting the top down in cold temperatures, does something freeze up that stops the top from going down or is there a sensor that regulates the top from going down in cold temp, kinda like a safety overide. Is it possible that I caused any permanent damage that i cannot see?...like the hydraulic system?

I had this happen to me twice since I've had the car, the second time being today. The trunk opens up but the top doesn't move back, just stays in place. And yes there is a humming noise like if it were working. I live in south texas so I can't say its because of cold temps. Leaving work at 7pm, it was 79 degrees if i remember right. I stopped the operation and let the switch go for a moment, tried it again and it worked fine, no hesitation, pretty odd.

 

The switches act up
Next time it happens slam the trunk lid shut to jog the sw in there.
If that doesnt help thru the brush slot top right in boot is another limit sw. Give that a twang with your fingers.
