Subject: Re: PLEASE HELP AC


Sorry NO!!! There¥s a protection switch that indicates low freon gas pressure. So it always quits its job abbrubtly! Have you ever refilled the AC gas? If no, you can be lucky and have the system refilled BY AUTHORIZED PERSONS!!! NEVER try to fix anthing at you AC by yourself!!! Be sure to add some contrast fluid when refilling the system so someone can determine the bad part. (using UV-light...) On my 900TConv (93) the evaporator has a (very very small) leak and the freon gas disappears over 1 - 1.5 years... I had refilled it twice (with R134 ?or so, that's better for the ozon layer but disappears faster!) Maybee the anti freezing sensor was not well connected to my evaporator and so it was damaged - one of the theories that were told to me... ANYWAY - it¥s a difficult job to find the damaged part! You can check the safety (pressure) switch with a multi meter, it¥s located at the right front fender at the AC valve (follow the AC hoses) it has to be closed! Otherwise - search for a good AC-shop (maybee you find some better guys than you SAAB garage - be professional take professionals!) and have the AC system refilled (serching for leaks) I wish you luck, greetings, RCS Babu wrote: > Actually, what I would like to know is...which one should I try to replace > FIRST? > Is there a higher likelyhood that one goes out more often than the other? > I'm assuming that since the AC went out overnight it's a high likely hood > that it's > one of these relays...please tell me I'm right. > > Babu > > > Babu <dewanopsamell.net> wrote in message > news:Oreu6.20748$qv3.8025686nopsam5-w.sbc.net... > >> My 91 900 Turbo suddenly lost the air conditioning >> overnight.
