Window opener fault - Mazda 626

Anchises

Hi ,

My Year 2000 - Mazda 626 driver's door window had become erratic in the last few weeks.
Sometimes it would , while upping it , stop half way and reverse , and go back down again. If I opened and closed it a few times it would finally close .

Today it started happening all the time. Problem if it rains .

I examined all the wiring and especially at the terminal blocks - all seem ok.

I tried a second hand door multi-switch that I know is good. Still a problem.

I tried a second hand door opening mechanism. This changed the scenario a little !!

With it, the window will close and open every time in response to the switch, but when closed - after a second , it will reverse and come down half-way ...

BTW both mechanisms work perfectly when tested out of the car with no glass burden to carry.

Now I'm really puzzled ...

Could it be a safety mechanism - reverse if obstructed ? - as in say a child/dog has it's head out. Would it be normal to reverse if too much resistance was felt to closing ? Remember it actually closes ALL the way up before reversing.

Would appreciate any advise ...

you might just need to program in the stop point for the window.
On a lot of cars, you close the window, then hold the switch up for 5-10 seconds for it to recognise the up position.
You should lubricate the rubber channels too, and make sure there aren't any obstructions.

Looks like safety function being triggered to stop it going up, problem is most likely there's either dirt in the rubber channels around the window frame that the glass slides on or else they need to be cleaned using some rubber refreshing treatment to soften them up.

Thanks guys

I'll get a can of spray tomorrow and try that..

Hi,

I got the silicone spray - " Bardahl silicone spray lube - rubber care "

Sprayed it - cleaned out the channel - sprayed it again - waited a while to soak in.

No good

Still have the problem.

Now a wrinkle !

The driver switch is marked 'auto' . One pull upwards (gives two clicks = a double switch) causes the door to go up
fully and letting the switch go does not stop it going up.
That's normal.

However pulling the switch to the halfway (one click position) causes to window to go up under control - stop pulling switch = it stops
pull one click again = it carrys on up.
Do this in small steps and i can close the window to within a mm of being fully closed. Do it in one movement and it slam shut and reverses.

It seems to be associated with the 2nd click in the switch ( same with all three switch modules that I have).
Using the 2nd click ( auto close ?), causes it to go up fully and reverse halfway down again.
Using the 1st click (manual controlled close) will allow it to be closed in small increments and can be stopped just short of fully closed and it stays there.
If i completely close it then it will close and stay closed.

Still seems like the safety reverse mechanism is in trouble, any fast moving fully closed position will go to reverse.

Would this affect NCT ? It due next week !!!! Bugger !!!

Did you do what I suggested (holding the switch up in the closed position)?

@ Colm_mcm

Sorry I should have mentined that.

I did try . If i hold the switch up it simply opens the window down halfway - ie it reverses it from closed locked position.
So it's not possible to hold it up for a few seconds without thwe window misbehaving.

A friend of mine says to disconnect the battery for a while and then reconnect it and it should reset some setting in the ECU ?

Sounds a bit like Win XP = Did you try turning it off and on ..

Will try tomorrow. There seems to be some variation in the reprogramming sequences across models.

Not sure it works on my aged model...

Tried all suggested methods of reprogramming the switches ....

All failed to fix the problem.

Tried disconnecting the battery for a hour...Then tried all the reprogram strategies again ...

Still no joy.

Now I can only successfully close the window with the switch up at the first click.
If i go to the second click - it will reverse again.... Bummer.

I give up.
