Many people hate the Climate Control in the LX and 40th Anniversary. (Many don't.)
Several have talked of the prospect of swapping in a manual control panel/unit.
Prior threads have also mentioned the "A/M" (presumably for Auto and Manual) switch in the back, and that the manual units appear to have the auto function already built in to some extent.
As far as I know, however, no one has done a side by side comparison -
I bought a used manual HVAC control from a '93 to swap into my 97 40th. The climate control on the 40th was bugging me, as it only had two settings, 100% cold and 100% hot.
Well, it turns out that the control box for the 93 manual is exactly the same as the 97 climate control. All that is different are the face plate markings, the blank over the AUTO button on the 93, and a snap-in temp sensor on the 97 CC model (which also readily snaps into the 93 manual box). All the innards look exactly the same, the circuit boards share the same part number, and the connectors have the same number of pins.
This confirms that there should be no modifications needed to change the Auto Climate Control to manual mode other than flipping the switch on the back, because then it would basically be identical to a truck with the manual controls (other than the now unused sensors attached).
Also, I think the reason my auto CC mode wasn't working well was because the cabin temp sensor was unplugged (apparently from my earlier forays into the dash to install CDL and re-locate some switches.) It was also extremely dirty, so I blew it off with compressed air and re-installed it. This seemed to fix the all or nothing temperature problem.
As for a functional comparison between the 93 box and the 97 box, I have not yet had time, due to some technical problems with the 93 box and a wife who was bitching at me for working in the garage at 11PM last night.
