I paid to have them installed, and the work is barely six months old.
I'll have to dig back through my files and records to see what kind of warranty they gave me on parts and labor.
Though, yes, I agree, being out $280 isn't the end of the universe. I'd like my seats to work again though. It gets extremely cold here in the winter.
EDIT: All of the work done by the customizing shop has a 3 year, 36,000 mile warranty. Gonna talk to them in a bit.
EDIT EDIT: He's gone until Monday. I guess I'll have to wait for the final word.
I am glad you were able to catch the double invoice and find out a little more about the situation. The only issue I really see is having gone to 3 different dealers for various work. I would really try to keep it to one dealer. I guess up there in Minnesota heated seats are a necessity
