WHEN is the light in the switch blinking? If, for instance, I go out in my garage and fold the divider in the trunk down (so as to make the entire trunk open for luggage) and then I unlatch the top from the frame - the windows do down.

Now, I press the button to lower the top - the light blinks at me, indicating I have an error - the error is that I do'nt have the divider deployed.

Sounds to me like the divider in the trunk is not deployed, or the sensor is bad. OR, the trunk lid is not closed all the way (or, again, said sensor is defective).

The fact that the windows go down and the light comes on when you unlatch is an indication that the sensor in the frame is ok.

Basically, they explained it to me that 2 of the circuits think the top is up while 1 of them thinks its down. They are going to charge me 1600-3000 dollars to repair the damage.

Damage from what? Sounds asinine to me.

When I mentioned to the dealership that I may not have it fixed right away (being still winter and all, and on the verge of purchasing a new house) and instead fix around may/june, they were very upset and told me that if I drive around with a known electrical issue, it would void the rest of the warranty and if anything else would go wrong in that period I would be held responsible.

So by not fixing something that is not under warranty the warranty is void? Sounds asinine to me.

So, my questions are, is this a common issue with the roadsters that I am just not uncovering? Am I being overcharged? Should I take to a couple other dealerships and get estimates/assessments done since this isn't covered by the extended warranty?

Yes, it is a common symptom, the "my light comes on, my windows go down - then nothing" is a complaint we hear around here a LOT. It is very often the little sensor on the driver's side in the trunk that determines if the divider is deployed. Yes you are being overcharged. You might try other dealerships, but dealerships don't seem to be very good with these cars.

Again, exactly WHEN does the light blink? I"m headed to bed, I'll try to check the thread in the morning!
