Dear Doctor: I would like to give my husband a seat heater for his 2000 Chevy pickup truck. How expensive are they? Do aftermarket seat heaters work — and where would I get it installed? Maryann
Dear Maryann: Aftermarket seat heaters work great. The average cost is $250, installed. I use the Check Chart brand and I’ve never had a problem. Make sure you get the 2-Level heat range.
