having an issue with the power trunk release. Some days it works others it doesn't. The days that it does NOT work, I can't get it opend at all, the push button near the sun roof controls wont open it, the key fob won't work I just get a double beep and double flashing of the tail lights and even if I have all the doors unlocked the manual lever wont open it aswell. Every thing else on the key fob works fine including the rear glass release. Any Idea's?
