Hi all, 

I am having an odd issue with the electric windows.  

They seem to have a mind of their own. 

I sometimes return to the car to find all the windows down. Sometimes they do weird stuff like all opening when I unlock (I didn't hold it, I know about the long press/hold function ). 

Can I just pull the fuse for the windows or unplug the motors or some other similar hack?

This probably down to water in the driver's door control unit, remove the plug, drain the water from the unit, then reseal the connector plug with dielectric grease.

Thanks Kentphil1. I will be sure to check out your suggestion. 

 

In the meantime I have discovered that the electric windows fuse also operates interior lights/remote locking/mirrors too, but I can still lock it with the key in the drivers door.  I can live with it like this for now safe in the knowledge that I am not coming out to a car full of rain in the morning. 

I took off the door card today and found the plug for the control unit did indeed have water in it and the connector pins looked a bit nasty. 

Didn't have any electical grease to hand but I cleaned it up with electric contact cleaner spray and used a little smear of ordinary grease round the collar of the connecter to try block the water from getting back in again. 

 

I have re-installed the fuse and some wierd window niggles I had before have gone away. I just need to give it a day or two now to see if the phantom window openings have also gone.  I might even treat myself to a new battery for the remote and see if the remote locking works now. Lol.

Whilst the grease may attempt to stop water penetrating the block, it will not stop corrosion of the pins when the weather gets cold and damp.

 

The connection will condensate and the green corrosion will still form over time. Normal grease is conductive so cannot be used on wiring terminals, but a reasonably thin coating of dielectric grease which is non conductive, over the socket will sort the problem there and then.

 

Glad you are starting to get there.

Ok, so the best bet is to get hold of some proper dialectric grease for it. 

 

Cool, the door card was pretty easy to remove and reinstall so I can can go back and redo it with the proper grease.  

Thanks for the advice.
