....today it did not go up. After about half an hour it decided to go up.

This is on a 76 280C, the rear windows are real small, I would think they would be quicker.

Did you end up doing anything? I've had to replace a few regulators on my '72. One thing I noticed is that there is a spring on the replacement regulator on the most recent one I fixed that was installed in the opposite direction than the original. If yours has a spring on it, maybe you can reverse it and it will be easier to go in the up position if the spring is trying to force it in the down position.

My back right occasionally decides to not roll up for a day, I've stopped using it. My back left works ok, but slow. Want to refresh ll the power windows. Most intimidating part of this car to repair.

You guys have cleaned and lubed the tracks right? Sometimes you just need to do a bit of maintenance not a full on repair. Mine are manual but were difficult to operate when I got her, some scraping of years of crud that gets washed down in there and some silicone grease made all the difference. You can even lightly spray silicone to the felting if it's getting worn.
