They were at the rear of the car (near the door).

Once again, for the amount of ventilation you need for them, I find them pointless.

When you have to let in a TON of COLD air (30* and down) to avoid getting sick, I might as well as keep the door closed, not use the heaters and have my dog stand next to me breathing on me for warmth.
