Hi all,I have just got a 89 260e in pretty good shape but have strange problems with ac unit I had it check'd at a ac shop and they said it was fully charged and in working order,but they didn't what to get into it.It works sometimes but usally not .First question when it is working correct dose it cool good or just so so.I am asking cause I never had one before.Now the odd stuff sometime the center vents work sometimes not ,sometimes the fans blows other times not,it blew once with the control off,but most always the fan blows ,the acworks ,then I shut the car off when I start it again ,it dose'nt work.Ive been reading on hear and tried the temp sendor thing but still no good .Thanks for any info.Al
