Oh yeah, I"ve pressed the buttons (set it to floor), and the rear temp manage knob is collection to complete hot. It"s a manual a/c system, and the blower and mode buttons work. Plenty of warm from the front. I can spend the $15 to gain the information from TIS, yet I"d choose to avoid that.

I"ve made friend a composite of some images I got hold of off the web to get you started on the disassembly process:

Service hand-operated instructions room pretty scant. You may be looking at a physical clog in the lines, a bad solenoid, or an electrical control issue. Perform you watch the manage arm move when you occupational the panel knob? have the right to you relocate it manually? You can manually revolve on the valve using a 12v jumper.
