Auto Climate Control: Blower only runs at full speed
In my 1988 M30-530i, fitted with A/C and auto climate control, the blower motor only works when I turn the blower-speed-dial all the way to full-power (when the dial is moved past the "click").
If it's in an intermediate setting, it will work for about 1-3 minutes after starting the (cold) car. Then it will die and afterwards only the max-power setting will work.
Any ideas on how to solve this nasty bug ? (full-power blower makes too much noise for everyday use and A/C is quite cold at full-power :( ).
Thanks in advance,
Joop,

Its a bad sword, the slang term for the speed controller that controls blower speed.
Here on Bruno's site you can find some info about repairing or replacing it.
Your's is going to be the sword type Check here
Sorry Duey, guess i'm a little slow today...

Yes i have , thats where most of Bruno's write up came from, and I got
it from someone on the e32 board years ago, but i am definitely not an electronics tech and my repair on my own didn't last long and still didn't function quite like I thought it should so i bought a brand new unit from eurasian for 150... that was a new behr one not rebuilt... but this was a couple of years ago so I'm sure that its more now... Someone with a working knowledge of electronics repair i'm sure could do a better job than i did...

BTW, Bill...have you done the repair deal to the sword? I'm at the 1-2-3 works most of the time but definitely cuts out after a while. That and the "my car is catching on fire" smell a few days ago... Time to get out the old soldering iron and visit RadioShack, methinks!
