The amenities found on newer model cars leave some auto enthusiasts puzzled as to why you would want an older car. The fact of the matter is that some of these old cars actually had the same creature comforts in their release years as their modern counterparts. The functions were similar, but the technology has progressed over the years. Take power windows, for example. The most common power window mechanisms are pretty basic in nature, usually consisting of a simple regulator motion transmission, or cable drives.
Troubleshooting is pretty straightforward, once you get the door panels off. Some window repairs can be very simple and may not require removing any trim at all. If the windows don’t move at all, the first place to look at is the fuse box. Window regulators are high-current devices, and the fuse is sized just big enough to be able to open all four windows simultaneously. Common wear, age, and a few sticky window channels can easily pop a fuse.
If the fuse is blown, the window will stay in the position that it was left in, if the fuse is good and you can hear the motor, or the glass acts like it wants to move, then you’ve got some sort of mechanical problem. This diagnosis applies to our focus here. After checking the fuses on our project, we knew that there was power and that we would have to remove the interior panels.
Once we had an idea of what we would be replacing, we headed to Classic Industries in Huntington Beach and picked up all new regulator motors for the windows. The window motors for our Impala represented a small selection of the products that this industry giant keeps in stock. Classic Industry has become a one-stop shop for all of your Impala needs, specializing in everything from exhaust to the stock interior kits, and in our case, window regulators and switches. Now follow along, as we swap out and lube the windows in this OG, power-window 1969 Impala.
1. After checking the fuses on the windows, we knew that we had to remove the door panels to access the mechanical parts of the windows.
2. We knew that the main switch was working, but we needed to remove the power from it.
3. We removed the armrest screws and other screws that held the door panel onto the door.
4. The door panel had to be removed to get to the working mechanism.
5. With the panel off, it was easier to diagnose the window mechanism and see which bolts held the regulator in place.
6. After spotting the four-bolts that held the regulator in place, they were loosened to allow the regulator to become free.
7. This regulator needed to be refurbished, as it was weathered from bad weather stripping that didn’t keep the elements out of the car.
8. Three bolts and the motor was swapped out.
9. These were the new m Liberace Museum motors that were used to replace the old ones that didn’t work.
10. The regulators are different, but the replacement process is the same for the motors.
11. The internal gears were lubed and ready to be bolted back onto the regulator.
12. This regulator was also cleaned and ready to be updated with a freshly built motor.
13. When the regulator is bolted back on, you will see the dry spots that keep the window from going up and down properly.
14. We used some Justice Brother white lithium grease to lube the tracks and guides.
15. After checking that the windows raised and lowered properly, the car was ready to roll.
