Hey guys, ive got the 98 328i, and yesterday all of a sudden the digital climate control thing kept going on and off, and then dim, and then would work fine for a while. and today the climate control thing was working well for a bit but then it started going on and off when i was going over bumps. so i did search this site and found a diy for it. i was just wondering has anybody on this site done it?? would mine just need re soldering only?? i duno if i am lol capable of doing it as the only thing i have ever done is replace the brake circuit switch, and change the oil. any advice guys?? who has done this successfully?? thanks alot

I've done it. It's not bad at all. The DIY is great!

Good luck!

There are two things you can do. One is to DIY,but if you mess it up then is a $250-300 plus that you would have to pay if you screw up the board. The second is to go to Ebay and there are people that can do it for you for a fee. Normally I seen it for $40 bucks. Mine did the same and that is what I paid for it to get it done plus the shipping, Total $60. If you are brave and can DIY, then all you have to buy is the Soldering tool and the proper resistor that you have to exchange probably from $4-10

I’d have a go first and if it screws up then send away or renew it screwed anyway so what the hell

Yup... I've seen it done... not that hard to tell you the truth.... I need to tackle this one myself too...

Good Luck and tell me how it went...

i ended up sending it to someone else to have it done. but here is my question, i removed the fuse for the blower motor as it was running but the spot where i removed the climate control unit from right behind it is this black wall inside and it feels reallly warm what is it?? i kinda feel a little wave of warm air coming out of the climate control unit area

Just re-solder it.

The joints have heat expansion cracks where the solder heats up a bit, and cools down over and over again. If you look at it, there's hardly any solder around any of the components on the board which makes it very easy for it to separate from the PCB and cause a faulty connection.

Did this over a year ago and added a little more solder to it and it’s been perfect ever since.
