If you are a hobby or trained welder you can fix the regulator provided the only problem is a broken cable. Remove the entire mechanism from the door and lay it out on a flat clean surface.I bought 1/8 cable (1/16 is actual size but 1/8 works on mine) and silver soldiered a hollow metal nipple onto the end of the cable. You have to install the cable on the drum first...measure the overall length of the old cable and then the resulting tension will be correct. If the old cable is too frayed for a length calculation then install a long length of cable onto the drum bolt on the regulator/motor mechanism and use needle nose pliers to hold cable 'extended' against the spring tensioner.
The entire mechanism can be installed into the window/door frame with a twisting movement which allows the two frames and motor etc to pass by the door interior structure until it lines up with the bolt holes. If you're really careful and have small arms you can place the window on the bottom of the door leaning against the door away from you and all the way toward the door hinges. That way you avoid issues of window removal and installation into a curved frame and rubber seal.

By the way, a new motor/regulator complete assembly is about $100 so weigh that against your time when you decide which way to go.

    Sorry for the late reply but your driver side window cable has likely failed and the passenger side is about to totally fail. The cable gets bound up on the drum by wear and gunk so that it seizes and snaps. Depending upon your skills level would determine hiring it out or DIY.

You'll have to take the interior door panel off. there will be a couple of bolts holding in the motor and a couple holding the regulator on. they all have to come off to change out the regulator.

Color coded wiring diagram 1995 gmc sierra electric windows

Google the
wiring diagram 1995 gmc sierra electric windows I found several systems offering what you require.
But what is the problem, 99% of the time in that year the window regulator was at fault, it was made from a stapped steel housing verses an cast unit. We check the left switch for power, disconnect the two wire connector at the motor, and see if the motor has power to one side or the other in the connector. If the switch has power to it, and the motor has power to it as you press the button, the motor is at fault.

Good luck.

2000 gmc sierra truck windows will not work even after change motors

If you have a voltmeter/multimeter you can check the window relays to make sure they are actuating when you depress the button. You need to verify the power supply is regulating to the motor from teh window switches. Second thing you need to verify is that you changed not just the motor but the entire regulator assembly. no offense to some aftermarket motors but they are underpowered and produced in china, etc. They cant lift the heavier regulators in your truck that are factory regulators. Since it sounds like you are handy and replaced the motors yourself, then I woudl reopen the door panel and actuate the window switch. You will be able to see if the gears on the motor head are turning to actuate the cables on the regulator. If you dont see movement then the problem is with either the fuse assembly or power supply to the window switches. If you see movement then the issue is with bad regulators and or underpowered motors. If you purchase the motors from ebay, I would be suspicious of the motors... Good luck.

The fuel pressure regulator is located under the upper intake manifold or plenum. This large aluminum casting must be removed for access.I assume this is a 454 c.i.d.old body style pick up. 2000 was a split year for GM. Both old and new body styles.
