From Jason's Garage - 1964 Cadillac Power Window Relay Testing
Quick video showing how to test a Power Window Relay from a 1964 Cadillac with case removed and things to look forward that cause them to stop working. This would be applicable for other auto electrical relays.

Matti, Glad the video helped. I had actually forgotten about this video!

Thanks Jason again!
Power windows in my 64 worked only in emergency position so I started to inspect the relay. Found out that it was stuck. Easy fix with your video instructions and now I have power windows in my caddy!

I would bypass unless you plan on adding a lock out switch... and then you run the possibility of where to mount the switch if your 63 has power door locks, since the 63 power door lock switches were mounted at very front of arm rest switch plate, instead of up on the door panel as in 1964.

Ian, The 1964 Window Relay works in conjunction with the Cut-Out switch (lock out switch), found on 1964 Cadillacs but not on 1963 Cadillacs. It is located behind the carpeted lower left kick panel and mounted to the car body via 2 5/16" hex head metal screws. It is referenced in the 1964 Cadillac Shop Manual on page 16-110, Fig 16-128. I have insured a crop in of the llustration seen in Fig 16-128 below:

Went back and added a 2nd part showing testing of continuity across the high current circuit after relay case was reinstalled.

1963 RHS A/C kick panel - photos needed
Posted by SK on June 2, 2025 at 2:20pm 2 Comments 0 Likes
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,

Loud air moving sound within carb with cleaner removed
Posted by Dave Fehrle on March 23, 2024 at 3:23pm 8 Comments 1 Like
While checking my Carter carb with engine running, I took the air cleaner off and there was a very loud hissing sound of air. I placed a piece of paper over the carb and it didn’t move up or down, is this normal?
