C.C. Module Laws?
 

Racking my brain. What is the deal with buying a used climate control module? My old 01,X5,3.0 auto with the rear console blower is done. Keep blowing fuse 40?something, it has been diagnosed as done. BUT, finding a used one to fit my X seems nearly impossible. What are the guidelines, rules to be sure a working used one will work? They run about $115.- $175 on ebay. In BMW fashion there are numerous numbers/codes on the my unit, but none of the used match exactly.
Thanks to all those who can help with this typical BMW nonsense:dunno:.
PS: Does anyone know what all those numbers on the parts label mean? I figured out the year.

No guarantees on used elec parts. Buy one from a reputable seller, and maybe one that allows returns.

Plug in the specific part number from your module into Realoem.com. If you don't see a part number plug in your car's VIN at Realoem and pull up the part. You will likely see some other part numbers that say "Exchangeable retrospectively" In theory, a replacement part with one of these other part numbers will also work, although it is best to find the same part # you have. There are also differences in the avail button on the face of the module. Make sure the unit you're buying has the same functions.

It is unclear to me whether you will need to code the climate control module (IHKA) to your specific car using NCS expert or other coding software. I think you may have to. Please search yourself on this.

eBay has buyer protection and sellers will take back non working items.

I've recently had to return two separate laptop screens.

Make sure the listing says it's a working unit and you are covered.

(Typical verbiage: pull from a car in working order it tested).

Another one for buying thru ebay. I find returning parts easy if somethings wrong and a great selection.

I went thru a ton of bad ac clutch parts from a seller. They sent several and in the end ate the shipping to send them back and fully refunded my money. While annoying with all of the installs and removals they acted in good faith and covered all the expenses so I cant complain.

All great points. But, I see several numbers/letters on the unit paper. Is there a particular set of numbers that must correspond? Is one set the part number? Is the part number printed on the black plastic somewhere on the unit? I also heard I may need to program it, but I'll start with the classic BMW fix: disconnect the battery.

IHKA part nr. is the first on the label "BMW 64.11- xxxxxxx".

The module needs to be coded unless the donor was with same specs regarding for example: engine type, rear blower, Webasto...

I think I found one, but my BMW 64 number wasn't represented at Realoem. And it is just close to the unit I found. But just about all the other numbers match up. I 'll check to see if it's from a 3.0 setup like mine. It is working in the X that it was pulled from. Thank you so much.

For pre 5/2005, with rear blower, without Webasto these should be compatible models.

This exactly. They should be plentiful with cheap ones having broken buttons. You can swap your front panel if it's still good.

Found that list and it is very helpful. I found one in Spain, but I am sure I can find one stateside. No rush, BTW, I figured out what the fresh air wheel is for on the center top dash. When the unit crashes in temps above 70F.,it opens the water heater valves and hot water flows through the system. It's full heat on. However, if I adjust the fresh air wheel, it allows cool air to mix with the hot flow and lowers that cabin temp. Weird,but works for now. FL really never gets that cold. Thanks again.
