A friend recently bought a 90 745 GL. It has an intermittent electrical problem, which causes the power windows, radio, and turn signals not to work. The engine runs normally, and other electrical items work. When the problem occurs, it begins when the car is started, and remains until the car is turned off. It may or may not happen the next time it is run. My first thought is to suspect the electrical part of the ignition switch. Has anyone else experienced anything like this? If so, what was it?

I just bought my first volvo last week,after a lot of research on durability etc-its a 1990 740 gl,and first trip after e-test and certification(this car has 200,000 kms on it) a very similar problem happened only after 2 minutes of driving with no radio or signals the car lost what felt like ignition or fuel pump feed and left us on the side of the road,after a tow and the embarassment of borrowing my inlaws buick with
360,000 km on it to finish our trip, im going to tear in tommorow--does any one else some input on this problem--ignition switch sounds sensible to me.

thanks

That's one of the two common symptoms. The other would be sticking in the Start position when you let go of the key.

If that is the problem, just jiggle the key back and forth with the car running and see if you get power back.
Sure sounds like the switch,
