I'm thinking about buying some. I think I saw some on Jegs for about 100 bucks a peice.

I've got leather seats and they get pretty damn cold, has anyone used an aftermarket seat warmer before?

 

Yeah and a while back my truck was throwin' codes well the stealership endind up having to take my seat out to track down some wiring, and well needless to say now I need to take it to the shop who wrapped my seats and installed the heat, stealership fucked something up. Other than that they worked great.

 

on the same topic, but wont help you...GM actually sells an accessory seat heater kit for the GMT900's. its under $300 on gmpartsdirect.
