From what I've read you can get the faults to display by starting the rover while holding down the AUTO and AIR DIST buttons.

On the 2000 model there is a AUTO button but 5 different air dist buttons. I've tried lots of combinations with no luck and have the fault ! on the display.

Is there another way to do it or is this a auto logic/test book thing?

I know it's a bad blend motor since A/C always works but heat will only blow out passenger vents and the drivers vents always blow cold while passengers are hot, but I'd like to confirm.

BTW, Rebuilt my valve block last weekend with the Rover renovations $25 kit and it worked great. I had a bad leak on the block end seam where the check valves are. It solved the overnight drops and height adjustments happen a ton fast now. It's a full afternoon job but is clean on a table and I have a much better understanding of the whole EAS system now.

Also installed some back up shrader valves that will allow me to bypass the compressor and valve block if need be, allowing it drive as long as the line and bladders are good.

I think that you need a test book to read the codes however, I not sure. I never saw any of my tech read Hvac codes with out the test book.

Remove the HeVAC controller, jumper the blend motors to power with a fused jumper. If the doors don't move, you need new ones.

FWIW-you probably need new ones due to the cabin air filters not being replaced often enough.
