Question about 2003 Saab 9-3
I have a Saab 9-3 Vector Turbo 2003 Salon and I have a major issue with my number plate lighting system not working. I tested the voltage going to the light bulbs and it is around 13-14V when the engine runs, however I noticed that when I test for current it is zero, hence why the lights do not work. Also when I apply the multimeter to the positive and negative cables and then plug the lights and boot locking system into the socket from the source feed, the voltage goes to zero (probably meaning a short somewhere). I tested all the cables for continuity from the plug to the lights circuit and they all link which means that the cables from there are ok. I also took a feed using other external cables I made up from the socket before the light socket directly to the light bulbs (closed circuit, which should create a current) and the lights still do not come on. I suspect it's because there is no current somewhere. Does anybody know how to fix or has experience with this as it failed the MOT and the garage is charging me a fortune to fix it. Thanks in advance.
It seems to be an earthing problem. Check resistance from the non 12V side of the circuit to the earth (remove the bulb and check from the earth side contact), either direct back to the battery negative terminal or any other part of the body metal (i.e. where there is a screw or bolt into the body panel of floor pan?) Doing a continuity check along the wires must point to the fault.

Take the car to Autozone, they will read the codes via OBD II for free. Other parts stores may have the same policy ... call first. My VW dealer charges $40 to pull the codes!! I bought a low-end OBD II reader for $50, as the wife and I both have VWs.
White smoke is usually antifreeze, the most frequent cause of this is head gasket blown or cracked head ... big bucks. Hopefully this is not you. Unless the car had a dramatic overheating incident, for most makes of cars, this should not happen until you have over 100K miles, probably closer to 200K.
White smoke could also be break fluid sucked in from power brake booster. If it's brake fluid, it will smell very bad.
On cold days, when the car first starts, white smoke can just be normal condensation in the tailpipe ... if it happens after the car is warmed up ... it's something else.
Check your coolant overflow tank level ... if it's very low or empty ... put water in (don't bother with antifreeze yet in case you are burning it up in the engine).
Good luck, ..ajm

SOURCE: fault with saab 9-3 aero
Hello I have a saab 9.3 SS 04 and had the same problem.
- intermittent wipe doesn't work, at all
- windscreen washers don't work, at all
- "normal" continuous, and fast wipe work, but the wipers
freeze in the middle of the windscreen if you let go of the
control stalk, rather than sweeping back to the resting position
- same "freeze" happens with the manual wipe (push down on the control stalk)
The weird thing is that, this morning, for about 10 minutes, it seemed to fix itself,
partially - the washers started working etc - but the intermittent wipe still didn't work. However not long after that it went back to the symptoms described above.
also if I unplugged my car battery for a minute the washers worked for several seconds but again same problem occurs.
Solution is to replace your wiper motor. its that "simple"
worked for me. The wiper motor has a lot of electronic stuff and seems to control the washer engine.
