Here's the deal i bought window deflectors for my car, They have been on there for a few years well recently the 3m tape started to get brittle and the deflectors stated to fall off. My back passenger one was flopping in the wind while driving so i took it off and threw it in the trunk, For the three days being in the truck it broke. My question is does anybody have a receipt from there purchase of the autovent shade deflectors, That way it will be under warranty so i don't have to go out a buy a new set just for one. I think they are under warranty still?? Any help would be great.
