Electric roof wont work is the a manual way to opperate it ?

This needs to go to the dealer to have the systems control module scanned for fault codes during an "active" test cycle.

no circuit breaker but relays and fuses for that and sometimes the electro magnet stop working too.

yes there is a manual winding mech. i think under around rear seats,thats where the relay and fues are for the auto roof, normally its quite easy to get the motors working on mech, you need multi meter , fuses and a psare relay.

Probably a realy trying to close and failing.

Hi David:

First, check the fuses for the hydraulic motor; if they're blown, replace and monitor (why did they blow? Perhaps an overload, or ...) These fuses are located in the engine bay on top of the fender by the front right wheel housing.

Next check the voltage supply to the top switch, possibly a loose connection or broken wire.

Also check relays C (raising top) and D (lowering top) under the rear seat.

Lastly check for voltage at the pump, also under the rear seat, when the switch is actuated, and that the voltage polarity reverses when the switch is actuated the other way (up or down).

After that, it's a hydraulic/mechanical problem. Check the fluid level in the pump reservoir (use SAAB fluid to top up if low) Fluid level should be at the upper marker with top down, and at the lower marker with top up.

Check behind the rear seat side panels that the piston shaft is still properly attached to the roof mechanism bracket at one end, and the piston itself is still firmly attached to the body. Look for any leakage from the system.

If all tests out OK and looks good under the rear seat and behind the side panels, then there is the possibility that the piston seals have failed and the fluid is just circulating around without activating the piston. Pistons are available (http://www.convertibletopguys.com/cgi-local/displaycat.cgi?cat=584 - scroll down) but the entire system should be removed to avoid getting hydraulic fluid on the interior.

However, that fact that you can operate the hood using the bypass valve (manually) would indicate that the hydraulics are likely OK, and that it's probably an electrical or mechanical problem.

Good luck!

Try buying one of the manuals I have listed from ebay , the guy is areal gent and the manual is a fantastic help. Motros from Saab are notcheap but if the tonneau motor needs replacing, try herehttp://www.neobrothers.co.uk/product_info.php?products_id=724 for areconditioned one

There are numerous technical service bulletins issued for the top. The list with the full TSBs is here.

its a 1996 saab. the red handle only releases the back motor which controls the front of the top. the trick seems to be to get the back window released.

what's going on ??
stuck ??
jerking ??
