The FAQ has pretty extensive information on the AC systems however, my problem was the blower fan fuse, # 28 on my 1990 760T, was shot. The blue AC light would blink steady. The compress would not engage and the blower would not work. The code I was getting was 2-3-3 2 3 3. I went to the yard and pulled a new ecc unit, pulled out the fan and checked it and put in the new ECC unit, still nothing.

Long story short, if you AC light blinks, check the fuse first!!!

Hope this helps someone in the future.

On my 780 the light started blinking like that, turned out to be a low charge. the mutiple uses of the same light on these cars really sucks. then again at least the light blinks to let us know something is wrong.
