Chevy pickup window regulatorI haven't had one of these model trucks since 1984, but from what I remember it is very similar to the 1982 truck I have now. (Refer to LMC Truck online catalogue for 67-72 trucks page 16 and 17 for an illustrated parts breakdown and a label of the components.)

1. Remove the door and window handles by removing the clip holding it to the shaft. A store bought tool available in any parts house is cheap or use a long thin screwdriver.

2. unscrew the door lock knob

3. Remove the inner door panel 4 Phillips screws along the bottom. You made need an impact screwdriver.

4. remove the vent window by CAREFULLY pulling back the main window felt from the channel and removing the Phillips screws from the front edge of the door. Carefully pull the vent window assy toward the rear of the truck and upward. You will need to rotate the assy 90 deg to get it out of the door Remove the rear channel assy as well.

5. slide the window crank back onto the regulator and crank the window all the way up past the top of the door opening. slide the glass forward until the roller on the regulator can be slid through the cutout in the glass runner. Slide the glass off of the other roller.

6. remove the 4 bolts holding the regulator. slide the roller out of the channel in the door.

7. Meticulously clean the channels in the door and glass of any gunk. lubricate with white lithium liberally prior to reinstallation.

8. Install is reverse procedure

Alrighty then ... The three bits of tape originally held some felt like material that is meant to sit in between the window regulator and other parts of the inside of the window like the bar from the quarter window. It does this in order to create a buffer between the regulator and the other bits so as not to obstruct the path of the regulator. When the path is obstructed the regulator wont operate properly. Moral ... replace all worn exterior weather stripping !

the regulator is inside the alternator and yes you can take the alternator apart and just replace the regulator.

Apparently after 36 years the window regulator needs some lubrication ! I removed the window and then the regulator and then lubed the whole of the regulator using a silicone spray. Fixed ! Getting the regulator and window back in the door was a whole other story.

I think in 70, they integrated it into the alternator.

A 1970 ford has a external regulator It's probably possible to adjust one by ajusting the contact points inside the regulator and I'm assuming it has a older style regulator but I don't think it will do much good. Replace the regulator. Disconnect the battery hook up the regulator hook battery up and boom it's polarized.
