Here is your fuse box diagram, but you are likely to need an auto-electrician with a pro grade scan tool computer to work out where the heater communication problem is. The Body Control Module does your heating.

Fuse box location. It is located on the driver's side of the instrument panel, behind the cover.

Does the vehicle have dual zone climate control, where the driver side and passenger side have different control? Sounds like a blend door issue on the driver side. Why did you replace the passenger side, was it blowing hot too when AC was on?

Usually the has to be replaced and make sure to clear all trouble codes

Unhook your batery and the the seats. When u put them back hook the seats up then your batery.

this can be a few things, you may have a bad motor, or a broken cable to motor or seat track and last maybe a broken track, the best way to diagnose would be to remove the seat flip it over while still conected,meaning; remove the bolts at the bottom of the seat then push seat back toward the rear seat this way you can see the track, now move the controls as you watch the track,it may go sideways instead of straight back or foward this will show you what side is not working from there you can see if its a cable broken or track or motor not turning .

Its more then likely the temp door broken or temp door motor broken/stuck. There is 2-3 of these motors under the dash on the side of the evap/heater core box. Some require extensive labor to replace, good luck

it sound like you need to replace seat control switch

lower the bottom portion, there will be two black cables. follow them toward the back of the seat, past a black round plate, where they become top and bottom cables. Push down toward the floor board on the bottom cable (my bottom cable is no longer black coated but rather a bare feeling cable wire). When pushing down on the bottom cable, pull the seat forward. As the seat does come forward the headrest will fold back at the same time. Not an easy find for me either, they should just make a release lever, but oh well..... I Hope this helps. Just keep playing around with those two cables until it finally does release.
