the air con on my 92 9000 cs manual doesn't work , i.e. the compressor won't run . i've tested it by putting a feed directly to it and then it runs , as anyone got any ideas as to the common faults on this , it is the manual air con not the fully automatic , many thanks jaa

The air con systems on most SAABS have a pressure switch which when there is insufficient gas in the system will not allow the pump to run to prevent any damage to the pump, if the system is re-gassed this should cure your problem, either that or the pressure switch is faulty but I find that hard to believe. Hope this helps

very sorry to bring up aircon again , but it seems by far the most common problem you can get with these cars , having never having had anything to do with aircon or indeed saabs before this is quite new to me , anyway i've now found what i hope is the problem the pressure switch is open circuit when i short it the compressor kicks in so i think a trip to an aircon specialist is needed to see if the system has lost it's pressure or to see if the switch is faulty , and i've got to get it in for it's mot to see what else needs doing but seeing as i didn't pay a lot for what i think is a great car i don't mind spending a bit of money on it ,
cheers john
