Update: BMW Climate Control Repair
A few weeks ago, I made a post on some problems I had been experiencing with the climate control system in my 1998 BMW 323. After some serious "googling", I found that it's the result of a widespread defect in a capacitor installed on the climate control circuit board. I decided I'd attempt the repair since the intermittent operation of the climate control system was extremely annoying.
My greatest difficulties were in removing the circuit board from the plastic housing. The board was wedged into the housing and secured by two tabs that fit into holes in the plastic housing. It took some brute force and creativity to remove the circuit board without smashing everything to bits.
Second, it was difficult to install the replacement 0.47 uF electrolytic capacitor on the circuit board due to its proximity to other components on the board. I ended up leaving a good deal of wire lead on the capacitor once it was soldered onto the board since it was a really difficult space to work in.
I completed the repair in approximately 45 minutes. And, miraculously, the fix worked! I now have a consistently functioning climate control system. Woohoo!
