Question about Saab 9 3

1 Answer

Hi - I have a 2004 saab 9-3 2.0 turbo. The other day it would not turn over. We jump started it and it started right away. Tested the battery, alternator and the starter - all work fine. Car started fine by itself. Turned it off - would not start - waited a few minutes started up. Turned it off - and went through the cycle again. Please help.

Please check the day code on the side of the battery. Battery is rated for 24/48/84 months.

It may should 12.8V to 13.6V but the capacity is decreasing.

Check your service record on when was the last time the battery was changed.

The correctway is to check the ACTUAL CCA and compare the CCA rating printed on the side of the battery.

============

To troubleshoot this you will need a DVM or a needle type meter that can measure up to 15 amps.

Turn engine off and disconnect the neg terminal and put the meter leads in series.

With the loads from computer,clock mem,radio mem,and alarm,. It should be below 250 ma

If you see over 750 ma or higher then you are really got a drain in the system.

==============

Do not rule out the eletrical part of the ign. switch.

Check though these items and let me know is there any improvement.


I will check this poat later.

Hello, my girlfriend has a Saab 9-3 as well and her battery just died I think. Funny, she got it from a Regency Chrysler dealer and the battery is a 12v GM battery. Is this a problem? What battery...


No, a battery is a battery as long as its 12volts. I would take it back and have it tested, if its bad Im sure they will warranty it. This would be a good time to check the charging system to insure the alternator is putting out the proper voltage and amps to keep the battery charged.

1999 saab 9-5 while driving it is jerking, at times it does not start without a jump


If the battery cable are not corroded, replace the battery. The battery is a very important component of an electrical system. Any check engine lights? 99 models often have a hole burned into the turbo hose on the right side of the car.

Have a 2004 saab aero 9-3. Recently battery died. It was shorted. But 6 years old. Replaced battery. Now often when trying to start, makes one loud click and won't start. Displays flicker and/or go black,...


I was having the same problem with my 2004 9-3. I assumed the starter was bad and replaced it. I then charged the battery and found it wouldn't fully charge. After charging for several hours when I removed the charger I only showed 11 volts at battery posts. The new battery tested 12.8 volts and the car started well. With the car idling I tested and showed 14.6 volts at the battery post which confirmed my alternator was charging.

I do believe I replaced the starter in error and that it was just a bad battery. When my battery was failing I had dim headlights and flashing displays that you described and the clicking noises also. When I put jumper cables on my saab and let the bad battery charge for several minutes the car would start right up and the headlights would brighten up and even though the battery was bad the idle voltage at the battery posts was increased to 14.6 volts coming from the alternator.

Remember to remove the jumper cables quickly once the car starts to avoid possible electrical problems.

I have had bad starters in other vehicles that would draw a huge load on the battery and jump starting them would sometimes give enough voltage to turn the engine over and start it.

Bench tests aren't always correct because the components aren't under a true load. I had a brand new alternator fresh out of the box last year that was bad and wouldn't put out good voltage even though it bench tested perfect. Go figure.

Check your battery voltage with the engine off. It should read over 12 volts if its charged.

2004 saab 9-3 turbo won't accelerate


i am the owner of a 2004 saab 9-3 that had the same problem. the car could barely make it up a slight incline.

after diagnostics, they determined that it was a faulty "pedal travel sensor" (engine code P1238), which cost $590. after labor and taxes, my total came to $747.53. yikes.

sucked to pay that much, but it fixed the problem.
