TAKerry Posted April 17 Share Posted April 17 Very well may be a fuse. I doubt both motors died at the same time. Link to comment Share on other sites More sharing options...

Look at a wiring diagram (in the Fisher Body Manual) and locate the wire or connector that is common to that side of the car. GM didn't fuse the two sides separately (and used a self-resetting) circuit breaker anyway) so that won't be the problem. Asking the interwebs for help will get you a huge number of incorrect suggestions. Troubleshooting with a test light is the only way to fix this problem. 2 Link to comment Share on other sites More sharing options...
EmTee Posted April 17 Share Posted April 17 Another common issue is a broken wire in the loom that passes from the driver's door to the A-pillar. The passenger side windows get power fed from the master switch on the driver's door. Also check the connectors at each switch, as Joe mentioned; those can work loose also. 2 Link to comment Share on other sites More sharing options...

This ^^ applies to almost all technical questions people come up with in their daily endeavors, be they about fixing cars, household items or gardening. I’ve often said that if you have to ask help for basic/common sense technical problem solving in online forums/platforms you probably shouldn’t attempt to diagnose, fix or be working on it in the first place.

Perhaps a bit harsh, but I get your point. On the other hand, I don't see a problem asking a question like that on a forum like this - particularly when it comes to electrical issues. There can be dozens of reasons why something like a window stopped working, but it can be helpful to reach out to learn about the most common causes for a particular make/model, as that can allow even someone with reasonable expertise to focus their investigation and save some troubleshooting time... 2 Link to comment Share on other sites More sharing options...
Bhigdog Posted April 17 Share Posted April 17 Don't have a dog in this fight but personally I'm a lot more inclined to help a person who has already exhausted his options by consulting his shop manual and done as much trouble shooting as he is capable of.............Just sayin...........Bob 1 Link to comment Share on other sites More sharing options...

Asking the question isn't the problem. How does the person asking know which answers are correct and which are BS? (OK, there's an 80% chance of BS). 2 Link to comment Share on other sites More sharing options...

Deadpurpledog Posted April 18 Author Share Posted April 18 Are the motors for the two passenger side windows the same? Who do you most trust to,provide replacements, please? Link to comment Share on other sites More sharing options...
EmTee Posted April 18 Share Posted April 18 The window motors are all the same, however, they are mounted to regulators specific to the window location. If your troubleshooting shows power is getting to the motor and it fails to operate, 9 times out of 10 the motor can be fixed. The motors are quite robustly designed and usually if disassembled you'll find the gear drive is packed full of old, dry, hard grease and/or one or both brushes are stuck in their holder and not contacting the commutator. Be careful if you attempt repair, however, as there is a strong clock-spring on the regulator that can hurt you if a finger is caught in the wrong place. Remove the motor with the window up and secure the window somehow to stay up when the motor is removed. If you want to send your motor(s) out for service, contact Steve Lorenzen (ROA #5684) at fostermom1962@yahoo.com . Link to comment Share on other sites More sharing options...

I don't know if the 67's had a relay that might be mounted just above the emergency brake mechanism. My powers windows on my 71 stopped working and it was the relay. this is what it looks like.

Deadpurpledog Posted April 21 Author Share Posted April 21 Thanks Robert. Going to tackle this week . . . will let you know what I find. picture was fuzzy. Looks as though you have a lovely Riviera and have had it for a long time. Drive it regularly? Link to comment Share on other sites More sharing options...

If any windows work, the relay is not the problem. People need to look at the wiring diagram. 2 Link to comment Share on other sites More sharing options...
EmTee Posted April 21 Share Posted April 21 (edited) I'll blame this thread for shaming me into finally troubleshooting the inoperative rear quarter windows on my '67... The LR window was intermittent when I got the car and soon thereafter just quit working. The RR window was working until about 2 years ago. I started by opening-up the master switch panel on the driver's door. I had suspected a broken wire between the door and the A-pillar, but that was just a hunch prior to troubleshooting the problem. I removed the switch panel and bench-tested each of the window switches using my Ohm meter. All of the switches were functioning properly (~1 Ohm resistance when closed). With the rear seat bottom removed I was able to remove the L and R inner quarter trim panels, exposing the window regulator mechanism and motor. With the motors connected I verified that I could read individually read continuity between the UP and DOWN sockets at the master switch connector and chassis ground. This confirmed continuity of the UP/DOWN wires and the armature brushes in each motor. Next, with the ignition ON, I verified that the 12V feed was present at the center socket of each of the rear quarter window switches. These checks told me that there were, in fact, no broken wires between the master switch and the windows. Next I used a separate 12V battery (the car battery was disconnected) to feed the LR motor directly. I got an arc at the switch connector, but the motor didn't budge in either direction. At this point it was looking like a mechanical issue with the window mechanism. I removed the 3 bolts attaching the window regulator/motor assembly to the body, noting that the window was very tightly closed as evidenced by the bolts being pushed against the opposite side of their respective mounting holes; there was quite a bit of tension. On the bench, I connected the motor/regulator assembly to the separate battery using jumper wires and verified proper operation in both directions. With that, I concluded that the window was jammed shut and there was no electrical issue. I then removed the small track at the rear of the quarter glass, allowing me to clean and lubricate the channel and wheel (attached to the glass). I did likewise on the short channel attached to the regulator arm and the forward window roller. After first 'bumping' the motor DOWN to partially lower the regulator, I then reassembled everything and lubricated the long, forward track (which I did not remove or disturb). I then applied 12V directly at the LR quarter window switch connector, running the glass up and down several times verifying smooth operation. I then moved to the RR window and before doing anything else I applied 12V at the switch connector and to my surprise, the window moved down! Without disassembling anything on the right side I was able to cycle the window up and down using my jumper wires. I decided to simply lubricate the rollers and channels using a spray lubricant w/ straw. I then ran the window up and down several times and verified smooth operation. I'm now ready to reassemble the rear inner panels and reinstall the rear seat bottom. The last thing I want to do is try to clean the socket contacts at the master window switch, as the contacts do look a bit dull and dirty. I sprayed electrical contact cleaner into the socket holes and connected/disconnected the switch two or three times. I'd like to attempt to squish the socket leaves a little tighter together any apply a bit of 'Ox Guard' to the switch pins before connecting the master switch for the last time.

BrianM Posted April 24 Share Posted April 24 EmTee thanks for the write up. You always have something constructive to add. I think you might have motivated me to dig into and clean up and lube my passenger window that has been dragging for months. 1 Link to comment Share on other sites More sharing options...
EmTee Posted April 24 Share Posted April 24 One thing I learned from this is that the adage "use it of lose it" seems to apply here. Once I get everything back together, I plan to exercise the rear windows on a regular basis to keep the motors and mechanism moving freely.

RivNut Posted April 24 Share Posted April 24 (edited) Larry & Todd Craft, owners of Sunrise Auto Glass, once told me that they’d never run into a problem with a station wagon having problems with electric windows. Their theory was that the kids in the back seat used them so much they never had a chance to get gummed up. Sounds logical.

EmTee Posted April 25 Share Posted April 25 Yesterday, before putting everything back together I decided to pull the door panels and lubricate the front window mechanisms; they both work, but slowly. Good thing I did, as i could see old, dry grease on both regulator /track mechanisms. I sprayed some oily lubricant onto the rollers and tracks, then exercised the windows up & down several times -- big improvement! I also removed a few small leaves and pine needles from the bottom of both doors... 1 Link to comment Share on other sites More sharing options...
