Re: Heated Seats
I dont have wiring diagrams at home (where I am currently) but I know chrysler uses alot of relays internal to the power distribution center to power things with key on power. I have seen a number of these relays fail. Your intermittant failure with one noted failure happening after a key cycle (the relay opened and closed while starting). I could be completely on the wrong track, If I have some time at work tomorrow Ill check out diagrams.
