i can tell you where the mixing valve was on my 90.  have not looked for it on my 02.

it was under the floor on the passenger side.  i replaced the boden cable on it.  it was accessed from the passenger side front bay where the blower fan for the genny was.  i got up there by taking some of the panels off on the right side of the bay.  it was up right behind the front cap up in no mans land.  at least on the 90, it was not accessible from the inside of the coach under the dash.

Thanks for your input. I will investigate in the blower compartment before I disassemble the dash. Will let you all know what I find. Looks like a good weekend project. Gets me out of some honey dos.
