Just how difficult is it to pull off the door panels for the right rear door panel? Was told it would take "special tools" to do it and the dealer wants $75 just to remove it. They claimed the regulator was broken last month and sh#t rigged it to stay up. A month later its falling down and the dealer claims it will cost me $700 dollars to fix the window . I dont where they came up with that but it seems really unreasonable. And dammit, if i can repair million dollar aircraft, i can fix it myself.....any pointers ?
