Question about Saab 900

1 Answer

I have a 1990 Saab 900S and the parking lights will not turn off unless I disconnect the battery. I also noticed that the car engine continues to run when the ignition key is turned off. Oddly this happens when the headlights are still on. If I turn off the headlights the car stops running when the key is in the off position. It all feels crazy. thanks for any help or advice.

Check the head light switch and the brake light switch.Also check the dimmer switch. This switches have got short causing this problems. The car is not turning OFF completely causing this problem. If there is a short in ignition switch then car will not turn off completely and due to short in the ignition switch the power off the car does not turns off.You turn the key to off but its short so the car actually is ok.Get this ignition switch also checked. With meter the voltage at the switches and the battery it should show 12 volts.If its not showing 12 volts ,then there is a short in wires causing this.Get it checked. Thanks. Keep updated for any more query. You can rate this solution and show your appreciation

    Brake light switch, located under the dash next to the brake pedal . Its control button gets pushed inward when the brake pedal is depressed.You may need to remove the knee "kickplate" to get access to the switch,if it got internally pushed.
    Thanks for keeping updated with your query.

How to get check engine light off on a 1995 Saab 900S?

Pull the battery cables off and let them sit off for about 30secs. If the code comes back on after the battery is disconnected than that means you have a hard code and will have to have the car scanned and reset. There are two kinds of codes, hard and soft, hard codes need to be scanned and reset soft codes are simple issues that by disconnecting the battery the codes will go away.

The check engine light is on my 1995 Saab 900s. I can not find a techician with the correct scanner.How can I turn off the light?

There are three ways to reset a check engine light.

1. Disconnect the battery, wait approximately 30 minutes, reconnect the battery. This resets the cars computer which also reset the check engine light. On newer OBD (on-board diagnostic) compliant vehicles this usually does not work. See step 2.

2. Reset using an OBD II reader. When you hook an OBD II code reader up to your vehicle, you can reset the computer using the code reader.

3. Fixing the problem. Generally the check engine light comes on for a reason. Usually it is emission related (sensors, gas cap) or electrical (faulty wiring). In this case the way to reset the check engine light is to fix the problem

91 900s Looses power, won't run through puddles/sudden power loss

Check all battery terminals and 12v power feed connections are clean and tight.
Check all battery chassis and ground connections are also firm and in good order.
Check any in line 'Maxi' fuse connections are firm.
Check for water ingress in any cable loom or bulkhead connector exposed to the water spray.

Sorry, gentlemen; NO 'C' clamps should be used on the rear callipers of 1988 to 1993 and 1994 convertible SAABs! Unless you want to replace the callipers, that is...

There is a calliper adjusting screw, at the rear of the calliper, hidden behind the parking cable. Unhook and remove the parking cable from the back of the calliper. You'll see a hex head located on the back of the calliper, between the hook to attach the end of the parking cable, and the hole through the bracket where the cable passes to the front of the car. The hex head is most easily seen if you hoist the car; it's not the most obvious until you've found at it a couple of times, then you can do it by touch with the car on a jack stand and without getting underneath!

Remove the hex head bolt, about a 12 mm or so wrench/socket, and you can then get at the calliper adjusting screw to tighten or release it as appropriate; the adjusting screw has an internal hex head socket, use a 4 mm Allen key. Likely the adjusting screw will be a bit stiff; spray into the hole with penetrating spray and let stand a few minutes before trying the Allen key.

Good luck!
