Need exploded view of rear heater assembly

[Capricious]

My rear heater is blowing cold air and will not change to hot with the temp control knob. Does anyone have an exploded view of the rear heating assembly and know how the temp is controlled? Is it vacuum assisted or electrically assisted? I would like to have an exploded view so I am not ripping all kinds of stuff apart to try and fix it. Thanks

Bobby have you switched the front control panel to "rear" and turned the rear fan switch to Hi and turned the temp to hot?

Does cool air still blow out the rear vents?

Right now it could be the fuse,Front/rear auxiliary temperature control switch.
Auxiliary blend door actuator or Auxiliary climate control module.

I can help you diagnose it without tearing into everything.

Yes, I have done all those things and it is still blowing cold from the rear vents. I'll take a look at the fuses and see if any are toast. Is there fuses located anywhere else? Thanks

The front blend door is vacuum actuated,the rear blend door is electronically actuated. Check out fuse #24 (10 AMP) to see if it's okay.

Checked out all fuses in dash panel and they were all ok.

If you're able to get heat/cold out of the front registers then I'll bet that the rear blend door actuator motor is bad or the wiring is unplugged or bad somewhere along the line.

Found it. The fuse from position #5 was missing. I have no idea why. When I was checking fuses I decided to see if there were possibly any that were missing, and that was the case. Thanks CHP for leading me in the right direction.

Interesting,#5 comes up as 10A Ignition Run Power Feed (Customer
Access) Must be a Excursion thing
