Clean > > "fender sensors" are the sensor for locking tires ? there are sensors mounted in the fenders (inner liner of the engine bay) which are the SRS sensors (decel). they are plastic cubes fastened to stainless steel brackets and are retained by stainless steel torx screws (3) which are tamper proof. If you open the hood and look towards the front of the car, it should be apparent what they actually are. Post back if it is unclear. > > > grease here as well.

A Ha, it could be that the steering wheel contact is bad. This would have to be replaced either by you or a dealer. It is not too bad from what I hear, but I have not tried it. You would have to remove the steering wheel. Do you have a Bentley manual? THis is a very good resource for locating parts as well as repair and disassembly. > > > > A/C doesn't work, fuse is already checked.

There are kits available here which have R134, fittings, o-rings which are about $30.00. THe link tells a lot about what to do: http://216.78.173.190/climate_control_folder/ac_retro.htm this site has a LOT of good information as well as www.saabnet.com The bulletin boards are good for info as well as the FAQ section. > > If you take the radio out of the car (2 u shaped hooks) there SHOULD be a > > switch on the radio to switch between the US frequencies and the europena > > that was what i could have tried out by myself... :) i am deep in my diploma thesis, so asking in a newsgroup is easier :) > > > probably won't break, but the bushes are cheap and easy to replace.

A floor jack is a hydraulic jack which has wheels and is low enough to slide under a car to lift it. This is used to compress the lower a-arm which compresses the spring slightly to get it apart. > > If it is a NA (non Turbo), you will probably find that the car performs > > better with middle grade gas (my '89 did).
