Well I finally have a warm bottom when driving my car the dealership installed the new heater cores (yes there are three heater cores on the bottom portion of your seat two for your thighs and one for your bottom) but upon further inspection they scratched the door sill while installing or taking out the seat. So I have to take the car back in and get them to replace the door sill that says Crossfire on it! so yeah there is a little Ahhhhh while driving and a ton of GRRRRR when looking at the interior.
