Question about 1998 Saab 900

Emergency convertible top lever switches

I went to a saab dealer to have my top programmed on my 97 Saab 900 and was told my ECU was bad, got another one and while looking everything over I noticed there are two elecrical boxes mounted on the emergency top release lever bracket that has a button on each box, it looks like in the normal mode the buttons are depressed and when the lever is pulled the buttons drop down. They are adjustable but the bracket was broken and the buttons were not compressed, do these boxes control power to the ECU? The mechanic said he has not worked on many saabs so I'm wondering if I bought a new ECU for nothing, I know something he did unlocked my 5th bow latches so everthing in my ECU wasn't fried (if it was) now I need to get it programmed and want to make sure I have everything right. but it won't be the same place, he even charged me 147.00 bucks for "diagnostics" that did nothing but leave my latches in the rear undone. I repaired the bracket but just need to know if the buttons could have been the problems reading the tech 2 from my ECU. Thanks

I don't think the buttons prevent the tech two from reading your ECU. However the top ECU times out and stops communicating with the tech 2, because it is designed to shut down to reduce electrical loads, in the car. IF the tech 2 fails to communicate push a window switch and try again. sometimes it takes many tries. But seldom on 97 or 98 will the top computer be bad.

1995 saab 900 convertible turn signals and brake lights not working


Check your fuses, even fuses not associated with lighting. If all ok it is probably the muti-funtion switch on the steering column, It is the switch that your turn signal lever connects to.

How do i put the top down manually on 98 900 saab


There's a red lever behind the rear passenger seat, fold down the rear seats to the trunk and you'll see it. Pull the lever down, and this should disengage the convertible motor. You should now be able to move the top up or down with some resistance against the hydraulic fluid left in the lines.

I have the same problem and my excellent Saab car mechanic told me to pull the switch and bring it to him so we can get the exact part number. That may be your problem. My problem is getting the part out of my car (has manual transmission).

Saab roof starts to open but the lid dose not fully open to let the roof fold down


The 94-98 Saab 900 cars have numerous top issues that are known. The primary issue is the design of the convertible top Tonneau motor that is located in the right rear quarter panel behind the light. The problem with the original motors was that there was not enough strength in the housing that held the motor to support the top movement because the teeth on the gear drive would get chewed up when the motor moved out of position. The failure of the Tonneau motor causes the top to chatter about half way up or down because the teeth of the motor gears would get chipped off. Replacement of the gears or replacement of the motor is the only repair and the convertible top Control module must be programmed after the repair by someone with a Saab Tech 2 computer tool which is used to program the top potentiometer settings. If you catch this problem early enough it can be repaired by using the bracket reinforcement kit.
Check latches is also a common failure which displays on the Saab Information Display (SID) Generally, this failure is due to problems with the micro-switch located in the latches that secure the convertible top when up.
Another issue with the convertible tops has been the control module that controls the top electronically. The major problem with this is device is that it looses the ability to communicate with the Saab tech 2 tools. This problem appears to have been solved in the newest versions of the ECM.
This TSB covers the known issues with NG 900 vert tops. There are numerous others for the 9-3 tops.
