I just installed SLK seats in my base model. They have seat heaters so I hooked them up to 12 volts and ground. I was not impressed. My questions are how long does it normally take for these to heat up? Are the heaters in the sides of the seats or the middle? Are they supposed to get noticabley warm to the touch. I was in a cold garage (34*F) and it seemed like the seat just got less cold (not really warm) after about 2-3 min. It could also be my mind playing tricks on me because I want them to work so bad lol.
