replacing a quarter panel is no easy task. it is spot welded all around the perimeter. To do it properly you will need to remove the rear window, the quarter glass, the trunk lid, rear panel, tail light, bumper cover, rear wheel, and inner wheel panel liner. every spot weld found will need to be cut, but only thru the outer panel. You do not want to cut all of the way thru both panels as you need to have something to attach the new panel to. After all welds are cut, there are welds under where the back window and quarter window go, and there are also welds in the sail panel that is between the quarter and rear windows where the quarter meets the roof panel. After all welds are cut and cleaned up you will want to cover all bare metal with a zinc based primer. You will want to drill holes all around the perimeter of the new panel and attach it to the vehicle with clamps or self tapping screws temporarily until you weld the new panel in place. You will want to fill in the holes you drilled in the new panel welding to the panel underneath. once all is attached you can remove the clamps or tap screws, if you used screws weld these holes as well, then grind everything smooth. finish up with a bit of body work especially at the sail panel where it meets the top, prime, sand, and now you might be ready for a trip to the paint shop.

I've done this many times
You will need a tubing cutter
Screwdriver
I think a 7 or 8mm socket
hose clamps
the appropriate amount of heater hose
zip ties

cut the steel heater line at the front in a place you can get access to,leave yourself enough steel hose on the rear to allow you to put the heater hose on cut off the steel hose and discard, and use 2 hose clamps on either end do the same for the other heater hose,this way is cheap and easy and permanant.Be sure that when you run the heater hose keep it away from hot or moving parts,use the zip ties to fasten it along the way,this should take about a half hour or so depending on your skills and working conditions,remember to buy some antifreeze to top up the system because you are going to spill some,remember to clean any spills animals love it and it is deadly.

The rear temp blend door is stuck in the cold position ,very common problem on vehicles with rear HVAC units . There is no valve , electric actuator !
Air Temperature Actuator
The air temperature actuator is a 3 wire bi-directional electric motor. Ignition 3 voltage, ground and control circuits enable the actuator to operate. The control circuit uses a 0-12 volt linear-ramped signal to command the actuator movement. The 0 and 12 volt control values represent the opposite limits of the actuator range of motion. The values in between 0-12 volts correspond to the positions between the limits.
When the HVAC control module sets a commanded, or targeted, value, the control signal is set to a value between 0-12 volts. The actuator shaft rotates until the commanded position is reached. The module will maintain the control value until a new commanded value is needed.
