Hi i need a diagram of the heating system like i wana a picture to see whats inside the air vent, read m y previous posts if u wonder why ... i still have no heat on driver side.

But the funny thing is that for the first few seconds i do! then u can slighlty hear a switch then only cold for driver and hot for passanger

 

what year ram do you have and i can get u a wiring diagram of the heated seats, along with description & operation, all that kind of fun stuff
