I'm glad to say that I have finally contributed something to the fleetwood community and the roadmaster heating/ac control unit WORKS COMPLETELY in the fleetwoods.

It works with all functions INCLUDING the diagnostic mode and its a direct plug in the ONLY modification needed will be to add a bracket to the roadmaster unit so that it will bolt onto the stock location but that is it.

All functions work if you press floor you get heat to the floor if you press auto it works in AUTO if you press blend then you get it blend.

I tested everything and it all works fine I got reaaaaaaaly lucky i bought this unit for $41 and it looks like new.

For those of you that are barely reading this for the first time You can use ANY a/c control unit from a 94-96 roadmaster into any 94-96 fleetwood BUT it must be option C68 a.k.a. the electronic unit, the manual push button unit might work but it won't be a direct plug-in.

I'll post pics really soon of both up close.

My specs are i transplanted a 96 roady unit into my 94 fleetwood. I'm going to work on the bracket for the new unit tomorrow.

Any questions just ask...

FYI the dimensions of the 2 units are almost the same.

the roady unit is smaller about 1 cm from top to bottom in the face area.They are exactly the same width though.

To anyone on this board with a '93-96 Fleetwood who has despised the piece of crap GM gave us as climate control (and isn't already following this on the Impala SS forums), stay tuned:yup:

This might end up being one of the most desired, relatively easy to do mods on this car EVER...and ocjmakaveli is being the first guinea pig.
Great job ocj! Mine seems to work ok, but there are times I wish I had a little more control over it.

Now, to get that EVO Steering disabled, if anyone cares...
Any installed dash pictures?

no in dash pics yet because although it does fit and all I have to make a custom bracket for it so that it will stay in place in the dash ill be posting mostly in the impala ss forum I'll have to cut the roady bracket off because it wont go in with them on and have to make custom brackets on top for it.

I installed a Caprice power steering unit when the Cadillac one died, no EVO and was comparatively dirt cheap.

Not to get too terribly off topic, but what's the difference in feel like? Any at all? I've always thought that an SS box would be the way to go if the one in a Fleetwood died, but have always wondered how much that would change the feel.
EVO isn't in the box, it is the pump. If you disconnect the connector, it goes into full pressure boost, making it feel like a 60's Ford for steering. BUT, it can be "fixed", but I posted sometime ago that I would figure it out, but no one cared, so I didn't either. Mine works fine with no issues.

Changing the box will make a difference, but the issue is the steering pressure is high to reduce effort.

Honestly, I think that I can disable it farily easily.

Oh, okay. I've been a little confused about that all for a while, like what actually is a good solution to EVO issues. Both our '92 Roadmaster and the '93 FWB have the funny "jerk" when turning slightly for a bend in the road, which can be kinda worrying at times, but it was never enough to think either needed fixed. I love how nice and "pinky easy" it is in a parking lot, but the overly done lightness on the highway drives me mad.

Oh well, back to the Climate Control! That's more important to me, anyway:thumbsup:

I'm assuming you loose the outside temperature feature?

Are any other function lost?
--
Wow HRS a little negative are we....Actually No there are No functions lost not one, all diagnostic works the outside temp is there too, blend, vent and all other buttons work. I've tested every feature and they ALL work.
:banana: :2thumbs:

the roady unit doesnt require the driver to press outside temp to view the temperature after you set your inside temp it reverts to the outside temp on the display :bouncy:

Nothing lost, no defects, no problems whatsoever I'm done with the install and spent about 20 minutes testing all the features and everything functions how it should.
Here's a nice pic of the outside temp. display on the roady unit fully installed in my vehicle.

Oh, perfect then! On the old '92 you have to press the button to switch between inside and outside temp--guess they just made it simpler!

Only issue for me is to see how difficult/what had to be done as far as the actual mounting. Ripping into that area of the dash is no problem, but I need to see how you mounted it and what I'm going to have to make/fabricate when I attempt the same thing.

EDIT: Still looks great and completely stock!
I'll be uploading pics in a minute

Here's some pics of the mounts i made on the heater unit they are simple and easy to make i just bought some metal L shaped pieces at a hardware store and some bolts for about $4.

i drilled a small hole in the unit carefully measured to be in sync with the stock unit hole location

I also left the top hole open per say so that i could adjust the height of the unit because I wasn't sure what height i would need it to be.

So really all that is needed is careful measurement of where the hole is from side to side and the up and down length can be adjusted while installing the unit I hope you can see what im talking about in the pic. I kept my installation simple and cheap and I wanted to get it done quickly because its too cold to be working outside.

btw the plastic is really tough so it holds the bolt and nut really well and it will hold up to abuse over the years.

I checked the dash and there arent many other options of setting the unit up this is the easiest IMO I would suggest if possible making both bolt locations adjustable by extending the holes instead of making exact holes with a drill just make slots with a grinder so that the bolts can be adjusted at the time of installation this will save lots of time and hassle. Don't get too thick of steel etc. because there isnt too much room above the heater unit when installed there is only about 1/2" max. in there
Okay, makes complete sense now that I see it, and very easy too.

Did you just chop off the Buick side brackets then?
