Gm motor identification

You will have to find the casting number on the block, heads, and intake to see if all those are original to that motor, but the block casting number will tell you what year it was made, and the types of vehicles it was used in. It might be difficult to pinpoint exactly what it was in originally if they used it in more than one type car, or produced it more that one year. You can google up a site that will help you find the block casting and decode it for you. Just type in GM engine block decoder

2000 chevrolet silverado extended cab drivers side window will not go up or down. passanger window works on same switch-changed switch-no difference-applies power to motor-window -window operates. any...

If the motor works when you apply power and ground directly to it the problem has to lie in the wiring or switch. I know you replaced the switch already but i would start with verifying that the switch is providing power and ground to the appropriate wires to the drivers window motor. You can check it at the motor first, if you don't have power there, check it at the switch. If you have power and ground at the switch but not at the window motor look for a broken wire. If you have power and ground at the window motor connector, yet the motor still doesn't work, do a voltage drop test to determine if there is excessive resistance in a connection or wire somewhere in the circuit.

Location of engine number on 1990 chevy blazer v6 4.3L engine

That can be tuff GM likes to use different places for the ID. Look on the passanger side of the block for a tab sticking out sometimes it is below the distributer on the back. Try going to the auto parts store and seeing if they have an open repair manual and look it up is the very best way to find out. Sorry I could not be more help.
