1995 Saab 900 - Answered Questions & Fixed issues

With the age of the car it could be that your grounds are bad somewhere which explains why essentially no lights work ... even though the bulbs/fuses are OK. You get power to these lights by having positive wires going to the light bulbs and the negative side of the circuit coming from the frame of the vehicle (referred to as the ground). Pull all the connectors that you can see and make sure they are not corroded. Check also that no associated relay that has anything to do with the rear lighting is not bad.

sounds like ignition barrel to me.

It almost certainly will be the switches unless you have a broken wire in the loom. There is a cheap piece of kit available on the internet called an op-com that will read these cars including the roof, that will give you fault codes and live data to see exactly where the problem lies.

Check fuses and relays first. Then check the wire connections at the motor. Sometimes the plugs get corroded and just need cleaned up and put back on.

the gear box on a auto has a switch in it that has to be in neutral to start engine this wears out. as its used alot. gearbox screwed up please explain. thanks

Did you check the oil. It has a low oil shut down feature. Below 1 quart low, ignition is disabled.

Could be the thermostat stuck open

Look for a test port on the fuel pressure regulator. It will look similar to the valve stem on your wheel where you add air to the tire. Connect a test gauge there..

Cannister is probably full.

my 1999 saab 93 converible roof will only open if i press the button twice why is this

p0501=speed sensor fault.Check sensors on wheel hubs.

Check leads are firmly connected on battery. New batteries have been known to be faulty. Needs power for locking door.

Turn it off. If that does not work cover it up

Is the alarm going off ? If so none.

What is the code?

central locking ecu in passenger foot well under carpet in front of door two tor ex screws attaches it to wall some times unplugging and replugging it in will solve the problem. meanwhile to get in gas cap cut out small perforated area in hatch near tank and remove the two torex screws this will release the gas tank locking pin

Convertable not so fun when the top doesnt operate? Haha. there is such a thing as a trunk lid sensor. Although I dont know where its located, its a good place to start.

i have same problem my roof window and wipers and ciggie lighter stopped working any idea checked fuse all ok

Fans come off and on based on a thermostat usually installed on the radiator. Follow the wiring from the fan to the thermostat. Test by heating and an ohm or continuity meter.
