Default Air Conditioning Control Unit

I've got '02 Coupe. The interior air conditioning control is the "dual zone" unit with lots of buttons. I believe there is also a "standard" unit that simply has 3 *****.

Can I easily replace my dual zone unit with the regular 3 **** unit?

I'm not sure on your question, buy why do you want to?

Two reasons:

1. I plan on doing the blue LED conversion, and I don't like the green text displayed on the dual zone unit. (this green text cannot be changed to a different color)

2. I like the simplicity of turning a **** to exactly the temp/fan speed i want - rather than the dual zone unit's "automatic" functionality, which is more of a pain in the a$$

Different wiring and connectors. Surprisingly, the vacuum schematics are very similar, so that should not be a problem. There could be some reprogramming of, or replacement of the BCM and/or PCM since they both have inputs or receive inputs from the HVAC system.
I guess it could be done, but how much?

If you want the electrical wiring and vacuum schematics, send me an email with your email and I'll put them into a word document that I can forward to you.

i agree, sometimes the automatic functionality can be a bit more of a headache than the 3 button. but in the long run on average days the auto unit wins in my book

good luck to ya!

(here a TTT for ya btw)

try using a tint on the vfd display. they do this a lot to change the color of dot-matrix and character lcd displays. you wont get pure blue, but closer too it.

i think www.matrixorbital.com has them

Thanks for the replies! Maybe i'll just hang on to my automatic unit...don't want to mess with different wires/connectors. I was hoping for a simple switcharoo.

thanks again.

(what is "TTT"?)

From what I have read here, you can't switch from manual to auto or auto to manual.

But I'm with you, I would much prefer the three ***** to the dual AC.
