Changed the oil and emptied the catch can...
View attachment 187671

I think there's a little less than last time. I'll have to check. Need to rotate still, will get it in the next day or two.

Topped off the coolant. Was maybe 3/4" low. Hope there's not a leak... Never been low before.
Ugh i need a catch can.

All my power windows seem slow and the driver rear had to be coaxed up last night with a few kind words before it started raining.

You can hear the switches and see the lights dim on the driver door when an individual switch is engaged. More so if trying to roll up both front windows at the same time.

I’m thinking the window regulator(s) might be failing?

Thoughts?
AC Delco or Dorman?

Going back my original post a few days ago. A few guys responded and thx. I had a chance to shoot a video in between the rain storms.

I started at the drivers side front and went clockwise to end up at the actual troubled rear drivers side window, which I originally posted about but did not explain well enough.

Engine is on. Down and up and you can hear the switch clicking each time I touch it on all the windows. So likely not the switches.

Bit of dimming and slight drop in the battery volts when holding the switch of one window or more so with multiple switches, e.g. both front windows.

Towards the end of the video you will hear the drivers rear window dogging it and very slow coming all the way up, even though it of course is only half way down.

I’m thinking that one regulator is going out based on the sound and lack of performance?

AC Delco, Dorman or other to replace?

Alternator and battery seems ok? Holds a steady charge and all other lights and functions are bright and steady.

Any further advice or thoughts are welcomed. Thx.

Thx man.

Sheesh AC Delco showing $105 for the regulator without the motor and Dorman $103 for the regulator and the motor on Amazon.

@Galante

You think I need both the regulator and the motor or just the regulator because it is going up, just very slowly?
