The Toyota Landcruiser Owners Club

[Crispin]

so today I decided to disconnect both batteries. After reconnecting both batteries, the drivers window was, as expected, confused. A quick 1/2 down and up and all is well.
Oddly though, the other 3 windows do not work at all. Not automatically nor "manual". There is only one fuse for all windows and obviously it is still ok as the drivers works ok.

How can I fix this? I am going to try disconnect the battery again and start from the beginning but don't hold much hope.

Now, I seem to remember that this is one of the situations that can be cured by holding both buttons down together on the remote for two seconds. I think that happened to mine.

No harm in trying.

Promise me you will not laugh.....

Problem solved.
I was out and decided to press the passenger  button. The window worked. Half way down, return up and auto is working. Did the same to the rear windows and all is well. You have to teach each window from their own switch (fair enough..)

The reason this had not worked before? The windows were locked from the driver's switches        Fool.

So, ensure the windows are unlocked before teaching each one individually.

Sorry if this is a silly question, but what are the windows supposed to do automatically and what are they confused about?  What are you trying to teach them?

You see - children for less than a week and it's all gone to pot already  

Glad you reset them OK - winter's coming along at a rate again

Hmm, I think I understand.  I'm surprised they don't just go down until they reach the bottom, and go up until they reach the top.
So if you didn't teach/reset them, what would happen when you pressed the down button?  Presumably you are saying they would go down to the bottom, the glass would stop but the motor would continue running and be damaged?  Sounds like a design fault to me.
Thanks anyway.

if you push the button down two clicks (auto) they will stop when you release the button and not continue as auto.

The reason you have to "teach" them is so they know where the limits are.

I believe there are two types of windows: ones with limit switches and ones with current sensors. The former do not need to be taught as the switches tell it when it's fully open or fully closed.
The current sensor ones sense when the motor has stalled (window fully closed) and whenever the window uses this amount of current, the assumption is that it is closed or jammed. Either way, it stops it.

The latter option (my landrover had them) generally does not have an auto up option as there is no jam protection. The current sense one inherently has jam protection.

It's not a design flaw but actually superior over the limit switches. Less cabling (an extra 4 wires per window for switches) as well as jam protection.

forgot to add:

In your scenario, the glass would stop and, assuming non of the linkages break, the motor would stall. It would, within a few seconds, overheat and pop a fuse due to over current. A stalled motor is basically a dead short.

I see.  Seems terribly complicated but I guess that's modern cars for you    
I'm guessing that the Landrover you had was a Discovery.  That would explain why you are so well acquainted with auto electrics.  You'd need to be to keep one of those going
