il faut simplement remplacer le condensateur bleu d'une valeur 47 micro-farad ou encore 470 nano-farad ce sont les meme valeurs en faite il simplement respecter la tension minimun de 25 volt voir meme superieur

The Repair First thing you have to do is get the Climate Control computer out of the car. To do that, first you have to get your Multi-Function Display out of the way. This is very easy; put your hand into your sunglass or whatever slot, put your fingers through the hole in the top of the holder, and push the MFD forward to pop it out:

Yes, I realize my car is dirty. Slide the MFD forward, pop it out, and let it hang out of the way:

Now, just reach into the MFD's slot and push the Climate Control computer forward with your fingers:

If you flip the computer over, you will need to remove the two wiring harnesses that connect it to the car. The Black one just pulls straight out; the other one, you flip the white lever and the connector pops out. You gotta love these BMW connectors...

Now that it's undone, get it over to your workbench, and take out the four screws on the back. They have a Philips head, but the screws are in tight and are pretty soft, so I ended up using a small flat-head screwdriver to get them out. You mileage may vary:

With the screws out, you need to pop the tab on one side out with a screwdriver, and then squeeze together the tabs on the other side to get the front of the computer off:

Next. pop out the circuit board with the display on it:

Next, remove the fan for the AC control (I think that is what this is, not completely sure). You might want to do this before you get the front of the computer off, because the screws again are small and soft and you may want to have more structural soundness to work with. It worked for me this way, though, so it's up to you. Remove the connector by pulling it straight out:

Next, you need to slide the main circuit board out. This is both easier and harder than it looks. There are two tabs on either side of the housing that hold the board in place:

I got one side popped out easily by pushing the board forward from the back with a screwdrive while applying some pressure to the housing. The other side was tougher -- I had to use one screwdriver to pry away the housing while pushing from the back with the other one:

It wasn't that hard once I figured out what to do. Push the board forward from the back until it slides out easily, and you end up with this:

The next thing you want to do is locate the proper capcitor on the fron of the circuit board -- it's the square blue one closest to the big blue connector:

If you flip the board over, you can locate the two pins for the capacitor in question by first getting into the general area, then looking for a small surface-mount resistor -- the two pins for the capcitor are right next to that surface-mount resistor (the screwdriver is pointing at the resistor):

I used a razor blade to scrape away some of the laquer coating from the pins, then used my soldering iron and a desolder wick to remove the solder from the pins. Once the solder was removed, I was able to easily pull the capacitor out from the front with my needle-nose pliers (I had to rock it a bit to break away the lacquer, but it came out pretty easily). I chased the holes with a piece of stiff wire (probably an old guitar string) of the right diameter, then inserted the new capacitor. A little solder later, I snipped off the leads, and the new cap was in place:

Reassembly was the opposite of disassembly, as one might expect -- everything went back together very easy. I popped the repaired computer in the car, and it worked perfectly! I'll let you know if it continues to work, but it sure looks good so far.

Total time to repair: About 90 minutes, but now that I've done it once, I could probably do it again in under an hour easy. Total price: 49 cents, plus tax -- I already had everything else. Even if you have to buy everything from scratch. it would still be a LOT cheaper than getting a new or rebuilt computer!

a+
