my saabturbo 93 year 2003 model,
sudenly abs and brake lights showing up at meter box... when the lights come out rpm meter, speedometer, air-cond all jam... if the light disapearred everyting will function well back.. on the same time i turn off enjin and try to start back but cannot start until the light showing.. when the light disapearred can start. why?

This has been happenning on my 2006 Saab 9-3 2.0 T also for about 2-3 months also. I have had no clues until today I learnt by accident that the lumbar support on my car's driver seat does not work anymore. Which means that there are broken strings/wires inside the seat and that move on braking and make clicking sound. I haven't checked my seat's lumbar support but will do soon.

Try your lumbar support adjustment and see if it is moving freely, that means it not adjusting the lumbar support. If that's the case, that may be the cause of the clicking/slight-movement of the seat.

You have to remove the nuts from inside the car behind the brake pedal - also remove the brake pedal switch.

i know this may sound strange but remove the brake fluid cap. on the cap is a sensor, do this away from any other vehicle and yours and shack the sensor by the cap a good few times. as fast as you can. then re fit the sensor see if the lights go off. sometimes it works sometimes not. this just because the brake light is on, this only usually comes on when the sensor thinks there is low brake fluid. and it can also tell the abs as well. and this is why both the lights are on. also make sure the fluid is at full markings.

Hi Joe, loosen the cap on the resevoir and very slowly turn the piston, you'll feel it going back in. (They are threaded)
*Just take your time, do not rush*

Have fun :o)

I have the same car... and the same problem. Did you ever figure this out? My personal email is [email protected] (if you would rather reply privatly)

I have a 2004 SAAB 93 and just finished replacing the brake pads and rotors yesterday. On the piston itself you should have two little notches. You can either or a GM rotor reset tool that will push into the two little notches and push against the piston while rotating it clock wise. Or the way that I did it was to take a C clamp and put the caliper back on the car. Clamp it on the back of the caliper to the front of the caliper so it will remain stationary. Then take a pair of needle nose pliers and rotate the two notches clockwise while pushing into the caliper. It will take some strength but you should be able to push them in. Be sure that you spray the boot around the piston when some WD 40 so it does not crack and or break during the process. If you have any additional questions about this feel free to email me.
