Hi,

Appears that I might have a dying window actuator on the back right passenger side.

Able to put the window down, but it won't go up from that door.

The driver control can put it up and down no problem.

Do I need a new actuator or could it be the switch?

Thanks.

 

Time to tear down back right passenger doors, clean connectors, also grease them! Silicon pray the grove where glass slides up/down. Your truck is old and needs constant maintenance in ALL places.

 

Any reco's for a good silicone spray?

Also, should I attempt to hit the connectors?

Thanks.

 

Electrical connections.....

 

Unplug ALL connectors, clear with given cleaner, brush with toothbrush or something similar, you can use these tooth brush pikes ones, to get into connector holes.
Use tiny screwdriver to remove any green residue that does not come off with cleaner/toothbrush.
After cleaning connectors, I spray it with some sort of oily based stuff to preserve connectors against further water damage.
Fluid film, Liqui-Moly Electronic Clean/Protect Spray, silicon grease.

Also unplug connectors between doors and body, they also need servicing, small chance of breaking it all to high hell if there is big enough oxidation damage.

For silicone spray, I guess anything that contains silicone is good enough, and if sprays. I would love to try out "DuPont Teflon Silicone Lubricant" someday.
