The SAAB 9.3 linear convertible 2004 that I own has a problem with the windows on both doors (front only) bouncing back down by around 1/3 when they are automaticly raised. Sometimes the windows close, other times they bounce down. If they bounce down, the only way to close is to raise and stopa few mm from the top and then raise again the last few mm's.

Does anyone know how to fix this. It started after the cars last 40 000 km service.


Also, does anyone know if the battery needs topping up. I just had the RACQ out to replace the battery that had three months left on it's 2 year warrenty and they filled the battery with 1 litre of water and advised SAAB's need water added every 6 months. Sounds to me like the battery is about to die and RACQ are trying to get it to die out of warrenty. Please advise...

The actual cause of the power window issue ended up being a near flat battery. I had the battery replaced and immediately the problem went away after I reset the pinch setting. It appears that the electronics can play up when the battery is about to go.

This is especially true for modern vehicles.

According to a mechanic I know he's had customers with the dash lit up like a christmas tree with warning lights (ABS, airbag, check engine, etc.) thinking they need $500 in repairs when all they need is a new battery.

The OE Saab battery we get in the USA cannot be topped up. Replacement batteries can be topped up.

That being said, only batteries operated in hot climates generally need topping up more than about, say, every 1 to 2 years. I don't consider where I live in Virginia to be a particularly hot climate, and my experience is that a battery has obvious water loss after 1.5 to 2 years in service.

There is another issue to consider, however, and that is that the Saab's voltage regulator is set for a maintenance free lead-calcium battery. If your battery is a "low maintenance" lead-calcium/lead-antimony battery, it will need to be topped up more often because of the higher charging voltage.

It's not your new battery that fixed this problem. It is your antipinch calibration that got messed up. So when you disconnent the battery OR take out the fuse for the windows, the antipinch/calibration will completely reset to being normal again :cool: Had this problem 2 days ago! It always somehow comes back.

Actually if the battery is disconnected, the Anti-Pinch MUST be re-set. It does not re-calibrate itself. See page 101 of the Manual.

Weak battery power would mean it is more likely that the anti pinch resistance / rolling speed occurred and down they went. A cause / effect thing.

Wouldn't that affect all 4 if it was a case of a dying battery? I ALWAYS have the same problem with my front driver window only.

JonV, that's what I meant ;)

If the battery dies or is disconnected, according to the book all four would have to be reset. I sometimes have a problem with my front passenger side window when it rains hard or there is an Ice/Snow condition. I attribute it to a bit more resistence triggering the antipinch.

Fuse 15 is the Drivers Door Control Module. Other than the fact it maintains power to the Motor/relays it does not set the calibration. That must be done manually.

P.101 says


After a power break, the electric windows
must be calibrated for the pinch protection
to work. Fully open and close the windows
at least twice. (Hold switch up the second time until you hear chime) You will hear a chime after successful calibration.

My question is if I pull fuse 15 and wait 30 seconds then do the calibration, will that do the trick. Only my driver side window isnt working, it goes down express not up.

Express up/down, although required for Pinch Protection is a seperate function, Just guessing but I think you may have a switch problem.
