Hi there people.

 

I am having the following issue with my power windows.

It has a mind of its own...

Sometimes when i press the button the windows roll up or down automatically.

Sometimes no matter what i do, i have to press and hold the button to get them to go up and down.

This goes for both left and right window regardless of which controller is used (driver side or passenger side)

 

Is there some sort of toggle i am not aware of that changes its operation mode ?

Or a known issue that i am not aware of ?

 

The windows always work, flawlessly. No weird sounds or inconsistent behavior (except for the issue at hand)

Its just that i for the life of me cant figure out why it works sometimes and other times it wont.

 

Thanks in advance !

No, there's no toggle. It might be faulty switches or a problem with the drivers window motor as it contains the electronics. It could also be broken wires inside the rubber door bellows.

Probably wont help you but when i have had the battery disconnected they wont do the one touch automatic,you have to hold the button.

You can reset them to do the automatic but im not sure how(think its holding the button for a set time when the drivers window is fully up or down)

I've changed the battery quite recently.

It started happening after that.

I've just put the windows fully down, and fully up manually. And cycled the key.

After which they seem to work automatically again.

Now they do go up and down by themselves when i press them onces.

I'm starting to suspect this might be some sort of calibration thing.

I'll keep an eye on it, see if remains this way or its just a fluke.

 

I don't think its a wiring issue, as everything checks out. Continuity, resistance. switch resistance etc.

I've worked extensively on the wiring loom in the past 3 years. The majority of the wiring in the doors, enginebay and boot have been replaced with heavy duty wiring (extra thick shielding) and weather resistant sleeves.

Just because i had the time, the wires were exposed due to other work. but mostly for peace of mind. (They are prone to have electrical gremlins under wet conditions)

The wiring inside the car was acceptable as it is not exposed to the elements. I re-sleeved the majority of it with more durable material. (Rubber)

it sounds like you have managed to reset them,they should be fine now unless you disconnect the battery again.
