BMW Climate Control Problems
I've had my 1998 BMW 323is for nearly 4 years, and have had a number of problems with it over the years. But the most annoying problem of late has been the intermittent behavior of the climate control system. The unit will turn on and off unpredictably while driving, usually during warm weather. The fuses are fine, and no amount of restarts will consistently put it back on-line.
I googled the problem a bit, and it seems to be a known problem with climate control units from BMW around 1998. One excellent web site details a fix which involves removing the climate control unit from the dash and replacing a capacitor on the electronic circuit board. I'm going to try this soon, and hopefully will have good results. It's disappointing to see the climate control perform less favorably than the old-school heater and air conditioning in my 20 year-old Volvo.
