My 2001 Saab 9-3 was having battery issues. I spent 2-3 weeks having to jump start it every time I used it.
The oil light had also been flashing on and off intermittently – and I was going to get an oil change soon.
Then, the last time I drove it, I had hit the 'W' (Winter) button, as it had been snowing. I then messed up with the jump start, connecting the red cable to the black and vice versa. There was a spark - but that's all. Hopefully, I had done no damage? I then jump started it normally - and got it going just fine....but it seemed now that every single warning light on the dash was on - all of them!
But - the car drove - and I drove it around the block, although it seemed to be a little sluggish - it felt as if the 'W' button was still engaged, but it wasn't displaying that it was still on - nor could I turn it on or off by pressing the 'W' button. Every warning light was still on as I drove it, too. But brakes seemed fine, steering fine.
I parked the car - and then yesterday got a brand new battery - at last! The car then started perfectly, first time - so that was good. But - still - every single warning light is showing. I have driven the car a few yards - and it still feels as if the 'W' button is engaged - although it is not displaying that it is on. Also - when I press the 'W' button nothing happens - it neither goes on or off - but it really feels as if the 'W' button is somehow permanently engaged. Pressing the 'TCS' button also does nothing - the panel shows that 'TCS off' - but I can't alter this either.
Any ideas? To me, it just seems that maybe the car is 'stuck' in 'W' mode and can't/won't reset. But why are ALL the warning symbols displaying? Surely all these things can't be faulty? Did my bad charge short circuit something? Is there an oil problem? Engine problem? Blown fuse? Any ideas??!!
Should I even be driving it at all?
Help!
Any d-i-y tips would be very gratefully received! I need a quick, cheap fix – just to keep the car going a little longer!

Even more important than all the alarm lights is the intermittent oil alarm. That comes on when the oil pressure is extremely low, and is usually caused by sludge especially on the early 2000 cars like yours. It also comes on if the oil pressure sending unit is faulty. I suggest either dropping the oil pan and checking for sludge yourself, or have an Independant Saab mechanic do it. If you drive the car much more, you are going to ruin the engine if the oil pressure is indeed low... Ron

^^^ Right. The oil light doesn't mean you need an oil change and you should not ever just think, "well I'm due for an OC anyway".

In automotive parlance, the oil light is akin to the home computer's blue screen of death except that it gives you the shortest of warnings at least. Basically, pull over NOW and shut off the engine.

As for all your idiot lights being lit at all times now, I think you fried something serious (or blew a lot of fuses) with that reverse polarity mishap. Make sure you keep current on the knowledge and know-how because all those venerable roadside DIY fixes; tire changing and battery boosting for example is a thing of the past. People just call AAA and have them do it and hence the knowledge goes away too.

Start at the front

Start by asking yourself "Have I ran over anything? Have I hit anything?" A lot of the wiring (i.e. Hazards, ABS) run underneith the vehicle, usually in a loom. If any of these wires have been severed, it could cause the warning lights to turn on..

If the answer is no, then check all your fuses. If they test good, given the information you have described and your abilities implied, then your gonna probably need to take it to a shop and have a professional check it out.

Most decent shops with a $16,000 scan tool can diagnose your issues for $65 to $80. Once you know the problems cause, you can start working on the solution.

Good luck.

Seconded. Even AutoZone gives OBD-II diagnostic checks for no charge just like they do free battery and alternator tests.

Worth a shot.
