I've been trawling the net looking for answers for a while about some worries with my dear SAAB. About 6 months ago the acc unit started to cut out intermittently from anything from a couple of seconds to a few minutes. First it was just occasionally but now its every day. All the lights on the unit go dead and the fan stops then it suddenly springs to life again as if nothing had happened. I ran the diagnostic program but it thinks its ok. Then the other day I saw the dashboard lights flicker on and off briefly. Any ideas?
