SPEEDOMETER WILL NOT WORK AND ABS LIGHT AND PARKING BRAKE LIGHT ARE ON .

SOURCE: ABS Light and Parking brake light on

check your fuses, then check the ABS valve located beside the master cylinder and the wiring to it and finally check your speed sensor, which is located on the transmission on a 2 wheel drive and on the transfer case on a 4 wheel drive. but make sure hat your E-brake is released as it will cause these lites to come on.

to begin i dont know what it means to say expensive or not how ever, all the lights at the same time could only mean one thing the problem could be in one of the diodes in your alternator is bad thus turning on all the lights on the dash board,

now regarding your brakes especially on saab;s shake or vibration is caused by uneven surface on the brake rotors (usualy the front) my suggestion is to replace the front rotors and the brake pads at the same time.

Assalamualykum.

Bro I had the same problem and the car is under repair now.

Check three points. 1) FUSES 2) ABS MUDULATOR 3) SPEED SENSOR

In most case it is the ABS MODULATOR, due to heating.

Replace the speed sensor in the rear end.

you have an abs fault. have your abs system scanned for codes.

your base brakes will continue to function normally
