I notice you have an 85, same here. I replaced my Monovalve cartridge, and made no difference. my problem is either heat, or no heat.

removing the cartridge would give you heat all the time. then screwing the top back on the assembly should still work w/o making a plate.

When you roll the temp wheel all the way to heat, and click it into the detent, do you get heat there? this is the only time I get heat. the other is in defrost which is the default.

Then I turn the fan on/off as it ghes too hot/cold.

I only get heat out of the def vents and the side vents. nothing on the floor. mine is a vac pod problem.

The 240D`s have the best heat system, all manual. never knew how good until we got our 240.
