I was driving my 04 crew cab yesterday and my little girl says from the back seat " I'm cold". My wife sitting up front had just turned of the heater be cause she was hot. So I got to thinking if there was a way to get heat to my rear seat. Excursions have it, so there has to be a way to modify that to work in a pickup. I havent ever been in a Excursion so please enlighten me to how it works. Thanks guys.
