I'm pretty sure it has been addressed but I can't seem to find the posts. My rear ac no longer produces any heat. Forward unit works great. What needs to be done to fix?
 
2nd on reversing valve, as long as A/C is working, that means the compressor is working. The only difference in A/C and heat is the valve.
 
U guys are great. Didn't realize it was a magnet switch. After tapping valve and it still not working I took magnet off and put a screwdriver in the hole in place of the switch. Nothing. Magnet no work. Traced wires and there it was. Vibration from compressor caused wire to break. Quick splice and I have heat !
