The rear windows will not go down on my 64 DeVille convertible. Front windows work fine. Any suggestions on how to get them down. 

Thanks Richard

Did you try from the individual window switches? From the master Driver Switch? With the lockout switch in the spring loaded far left Emergency Position?  
Can you provide any details on how or when they stopped working?  If they have worked did they work form individual switches and/or the master switch?  

Thanks for the quick reply. This is a great forum. They were stuck up when I  bought the car. I will try the Emergency position and let you know.

Thanks Richard

I am assuming then you tried from both the master switch and the individual window switches. Make sure ignition is on. With the Lock Out switch it doesn't matter. Ignition can be off. Basically bypasses the relay.   It is easier to diagnose with a full picture of how things are working or not working before you just start diving into the rubber conduit between the driver door and the body of car... although breaks in the wires in this area is a common problem area. The fact your right front passenger window works (assuming from master switch and individual switch) makes you wonder if it could indeed be isolated issues at the rear qtr windows or isolated to feed wires in that rubber conduit. Again, it would be helpful to know the full details before jumping into anything. It is also easy enough to just pop the ash tray/lighter/switch receivers up in the back and make sure they have good contacts before tacking the driver door conduit.

I will go slow and try your recommendations. 

Thanks for the help, Richard

Thanks for the quick reply.  I will look into the wire harness in the door. 

Thanks Richard

Did you get his figured out ?

My rear windows on the 64 won't run either.

1963 RHS A/C kick panel - photos needed

Posted by SK on June 2, 2025 at 2:20pm 2 Comments

Could someone post front and back photos of the 1963 right-hand kick panel with A/C?

My car didn’t come with the original kick panels, so it's a bit of a mystery to me how I should cut the backing board and carpet to fit around the A/C.

Many thanks,

Edelbrock Carb Block off Plates

Posted by Chase on March 12, 2025 at 2:05pm 14 Comments

Hey guys,

I have installed the same Edelbrock carb and have done everything the same as Jason’s carb and intake project. In the spring and summer months the car starts, runs and idles great! In the fall and winter months on a cold start, the car starts awful and wants to die until it warms up. I have to keep my foot on the throttle until it warms up or it will idle just terrible and try to die. Once it’s warm, it runs fantastic! Whats going on here? I was thinking of removing the…
