Did you test the low beam electrical circuit using a volt meter ? Look at a wiring diagram to see what all is involved in turning the lights on ? Do you know how to test electrical circuits ?
Also reading service repair manual about the head lamps opp. would be a good thing to do .
Headlamps
The major common components of this system are the body control module (BCM), ambient light sensor, multifunction switch, park brake switch, and the headlamps.
The headlamps may be turned on in 2 different ways. First, when the driver places the headlamp switch in the HEADLAMP position, normal operation occurs. Second, with the headlamp switch is placed in the AUTO position, automatic lamp control (ALC) occurs. During ALC control, the headlamps will be in daytime running lamp (DRL) operation in daylight conditions, or low beam operation in low light conditions.
The low beam relay and high beam relay receive battery positive voltage directly from the battery through the HDM and COILS fuses in the underhood fuse block. The BCM supplies a ground signal to the low beam relay coil for automatic headlamp control and normal headlamp operation. The BCM also supplies ground to the high beam relay coil for high beam headlamp operation. When the driver places the headlamp switch in the HEADLAMP position and the dimmer switch is in the low beam position, the low beam relay energizes sending current flow through the left and right low beam headlamp fuses to both low beam headlamps. The dimmer switch sends a ground signal to the BCM in the high beam position and a momentary ground signal in the flash-to-Pass (FTP) position from G102 to deactivate the low beam headlights and activate the high beam headlights. With the headlights in the low beam position, the high beams may be momentarily turned on or flashed by activating the FTP portion of the switch.
Low Beams - Standard
The standard low beam headlamps receive voltage from the headlamp driver module located in the underhood fuse block. The body control module (BCM) controls the headlamp driver module with the headlamp low beam relay control circuit. Low beam control is determined by a signal on the headlamp dimmer switch signal circuit from the multifunction switch. When the headlamps are requested ON and the headlamp dimmer switch signal circuit is open, the BCM sends a pulse width modulated (PWM) ground signal though the headlamp low beam relay control circuit to the headlamp driver module which illuminates the low beam headlamps at a 100 percent intensity level. The right and left low beam circuits are independent and are fused separately in the underhood fuse block. The LOW HDLP-RT 10A fuse supplies voltage to the right low beam headlamp and the LOW HDLP-LT 10A fuse supplies voltage to the left low beam headlamp. The right and left headlamps are grounded at G103 and G107 respectively.
Your best bet mite be to have a qualified technician check it
SOURCE: left low beam light doesn't light
Go to autozone and ask them to put it in for you..lol or o'reillys. Youd be surprised at how much they will help you if you ask, It would be hard for me to tell you how, but under your hood on each side of your radiator, you can probably see back of headlight. If not it may have to be removed, just look how it is held in place, If I didn't help you I will if you will provide me more info, I do this for free to help people, please give a me a good rating, I don't have anything to gain by trying to help but for a better rating

IF THE BULBS ARE OK CHECK THE HEADLIGHT MODULE(IT LOOKS LIKE A RELAY, ORANGE CASE I THINK) TRY WIGGLING IT,IM PRETTY SURE THATS IT. THEY GO BAD ALOT ON SAABS. IT SHOULD BE IN THE ENGINE CONPARTMENT
SOURCE: low beam head lights won't work
Check your relay switches under the hood fuse box. They should be a light grey from factory, they are about 1 x 1" in size and there are a few in there. Pull one out at a time and if they look brownish or yellowing replace. Go to Napa or Auto Zone for $15.99 a peice that most likely will fix it.
