ive not checked if the aircon still works as its fuckin freezing, but the heaters work at all speeds, just blow at window only!
after a while your face/head is so hot you want to turn the blowers off, but your body isnt that warm, and your feet are still freezing
was fine until i fitted a different headunit in the car, seemed to happen at same time...
PROOF, modifying your car makes it totally unreliable no matter what
