My passenger side window is misbehaving, I open the door and the window drops as usual but when I shut the door the window doesn't go up all the way. Then if I open the door again usually the window won't drop at all and it will catch on the a pillar.

I've swapped the door ecus over and the problem is still there.

The microswitch on the latch is operating fine and doesn't seem to be causing a problem.

The window will wind all the way up when I use the key fob, sometimes it will take a couple of goes though.

It seems to me that the window doesn't really know where it is, is there another sensor or anything that I can reset?

Thanks guys, does the window need to be in a certain location before a remove and refit?

Hi,

Did that and now the problem is different.

Press door release window drops as normal.

Door pops but doesn't open, (solenoid not powerful enough?)

Then you have to press the button again or put a bit of opening force against the door and it will pop open fully the 2nd time but the window will drop again!

Then you close the door and the window will only go half way up unless you use the window switched

Any ideas?

You can hear the solenoid operate, however it doesn't pop the catch like it does on the drivers side unless force is applied to the door.

Is this a solenoid issue or a door catch issue?

If I keep the door open and flick the catch closed with a screw driver, then press the door release button the door catch will never open on the first press - it always takes another go.

Is the door catch TVR specific? How about the solenoid?

I've had a poke around behind but there is limited room to see what is happening but have noticed the door catch is quite hard to operate by hand (where the solenoid attaches).

Thanks for that.

I've taken the cover off and cleaned the latch but it hadn't really helped.

I will unplug the wiring to the solenoid and have a look if its corroded etc.

If that's all fine, what would you suggest?

Solenoid not powerful enough or latch seized?

Ok, after lots of swearing and cut arms the door is now popping open like it should.

Press door button, window winds down.

Door pops and window winds down more.

Close the door and window winds back up to the first position.

It seems like the door button opens the window, then when the door micro switch is unpressed the window winds down again, which it shouldn't do...

Any ideas?

Is the microswitch at fault?

I'll try that but obviously shutting, locking, opening, shutting doesn't work properly so that leaves me to either go inside the cabin and wind the window closed using the spin knob or press and hold key fob for total closure a couple of times until the window finally reaches the top position.

I've tried swapping the door ECU's over before when it was doing it and the problem was still there, but I'll try again and see if it makes a difference this time.

Is there a way to totally reset the windows?

It's like it doesn't really know where the fully closed position is, it thinks half open is fully closed frown

I think it's the window encoder sensor thingy.

When I spin the window knob the glass moves down in 2 large movements. Nothing like the fully working side which moves down in 1cm increments.

Is the encoder behind the door card the only thing that tells the ecu where the window is?

Swapping the ecus didn't work :-(

The encoder is only a couple years old and don't think it could have got wet!

Swapped the encoders over and nothing changed.

Swap the door ecu's over again and now I have no windows working correctly!

Ahhhhh!!

Encoder's look brand new, they were only replaced a couple years ago maximum.

Door switches ay? These seem to operate and click correctly when I move the little arm, is there a possibility of them breaking down inside?

Yeah Paul said it could be a fault within the ECU or encoder.

I think tonight I'll strip everything down (again), clean all the connectors of everything. Check all the fuses as I haven't even looked there. Put the drivers side door back how it was to see if I can get that to work properly again. If that works then it is most likely a dodgey encoder I think.

Is there a way of testing them? Or is it simply just replace and stop messing around?

Put the drivers side back together and it works again.

I've ordered an encoder!

Replaced the encoder and it's still the same.

I believe it may be a fault with the microswitch.

I pulled all the wiring out for both and there was a ruddy great battery attached between the live of the door solenoid and earth of the microswitch. Could this be causing an issue if the battery was flat? I presume it's for the alarm, looks like aftermarket.

Takes the live from the solenoid and negative from The microswitch. Also there are 2 other wires that come off it and run off under the carpets somewhere.

It was a tracker.

No idea when it was put in but it's in the bin now and wiring removed.

Ordered a new catch and a door micro switch now so hopefully it will start working. Otherwise I'm out of options.

Does anyone know if there is a way to fully reset the system? So the windows know they're shut etc?

Cornwall :-(

That's the problem, there is no support down here. Closest is 150 miles away....!

I still can't work out why the passenger window doesn't go down in 1 cm incriments. It moves down like 4 inches a time. Could the rotary switch be at fault?

Fixed it tonight.

Turns out it was a loose connection inside the plug between the encoder.

Looks like I'll need a new loom or maybe do away with the plug totally...!

If Paul Smith hadn't had me probing around with a multi meter measuring voltages then I wouldn't have found the loose connection.

Top guy!

I'm just glad I know what the issue is, was really starting to get ticked off with the damn thing.

Next on my list is the reverse light!
