I don't use the rear a/c too much -- occasionally I enable it because my son gets a kick out of adjusting the air himself. Following that pattern, I pressed the dash switch yesterday, but no air flow fromt the rear unit -- however the rear fan and temp controls are adjusted. The light comes on for selecting upper or lower vents. The 30 Amp fuse ("Rear a/c") is fine. Is there something obvious or easy that I can check before taking it in for service?

Well, nobody had any input, so this must be an unusual problem, or one nobody cares about. Anyhow, took the truck in for service on Friday last week (also had all 30,000 mi service done). They said it needs a part called "Rear A/c Transistor" (no. 79330s2k941) that is on "indefinate backorder. Tim at Hondacurawold confirms part is not available. I was not able to talk to the tech, so this is all I know!

Do you think it will be fixed before you sell your vehicle, or will the next owner continue to wait for the new part?

I have a couple of questions for you, I am installing a full size spare in my X, but using a tire cover to help protect it. Did you do anything like that?

The second question, do you plan to get another SUV?

Thanks and good luck on your sale.

I think no input = unusual problem around here!

Don't forget to put it in the problem knowledgebase....hope your part comes in quickly! BTW, does the rear a/c work (blow + cool or heat) in auto/full auto mode (not with the rear a/c manual button pressed)?

(1) Full size spare: I do not have a cover of any kind on it. There was a thread back about a year ago on that subject. I think someone was considering some kind of cover.

(2) Selling MDX. Well, if anyone is willing to buy it while the problem remains unfixed, of course I would sell. My assumption is to the contrary, however. Yes, I am getting another SUV -- 2003 Ford Expedition, which is being build in the next few days. Yesterday, I began to regret not ordering the DVD Rear entertainment system. But it is too late to change and I don't want to start my order over!

(3) Rear AC. It doesn't blow anything with the "rear ac" button engaged. I never thought of checking it when the button was not engaged.

Yes, I may have been part of that same discussion, in fact I just got my full size mounted & balanced today.
The expy is a popular choice, in fact they are having a big expy free drive fair here in the Bay Area the middle of June. I will go, I will drive anything offered to me for free! Went to an Escalade one 6 months ago and got to drive pleny of cars like Bimmers that had nothing in common with the Escalade.
Best a luck to you in any case, with your new ride!

Still waiting for this darn part ("rear ac transister") on backorder. I consulted with Tim, who confirmed the part is not available, but who suggested that my dealer put it on "critical backorder." This is what that means (per Tim): A critical backorder is where there is a customer satisfaction or vehicle down situation at hand. They submit a special parts order with your VIN number, and the parts are upgraded and expedited accordingly, or pulled from
the stock of another dealer that may have one.

My dealer, though, says that they cannot critical backorder a part that is unavailable in the system and that all I can do is wait. Seems to me that Acura must have the part to use in building new vehicles, so they could divert it to meet their warranty obligations if they wanted to. Can I contact somebody higher up the Acura food chain? Anybody have any idea how to do that?

Make up a story!

Why not, the sales people & service writers do it ALL THE TIME...

Why not call Acura Care and say:

"I have a sick little girl that has monophelgistamonisisa, she needs the temperature to be no more than 73 degrees constantly or she loses consciousness. I specifically bought this MDX because her team of doctors thought the safest way to transport her between her temeprature controlled bubble at home and here temeperature controlled bubble at work would be in a vehicle with rear A/C. I really don't know where else to turn. Can you please help me get the "A/C transistor" so my daughter can get from her bubble??"

Worth a try...

Other thought:

If it TRULY is a transistor, meaning a generic voltage/signal control device, http://whatis.techtarget.com/definition/0,,sid9_gci213216,00.html, than are only so many substitutions available. Get the specs and then order a substitute from any electronics supplier.

You'll need to know a bit about the device that is 'bad', but often the info can be gleaned from manufacturers' websites:
