just looked at a 08 ducato the n/s window went down on it own got it to go up then smoke came from the switch on the drivers door and then the same from the other side
the window motor in the n/s door is very hot can anyone help

Did the motor fully stop when the window got right up ? Failing that almost sounds like a short to neg maybe in the conduit

it went up and you could hear a click then I went back down and I could not get it back up so took off the panel and the motor was hot

Have you tried unplugging it and direct power it ? Had a look on auto data the only thing it lists is wire breaks and alas no wiring diagram

just fitted a new window motor and 2 switches it will go up but not go down
the switches were burnt out is there some control unit for the window

The control unit that would control it would be the body module what are the voltages on the switches ?

to be fair not checked that where is the relay for the windows

Will have a look and see what can find tomorrow mate

that would be gr8 thanks

Have had a look , autodata doesn't list any seperate relays for the windows so unless there's a control module in the doors then would say they are integral to the body module

I am going back next week to take another look

anyone help

Have you had it back in then ?

back in today

Just in the middle of stripping the nearside window switch on my '05 2.8 because it got a little water inside and blew both door windows.

The way the switch has failed is almost bound to power up and down circuits at the same time. Guessed when you first posted that might have let out the magic smoke. Can't believe I've got the same problem.

Having a bit of a warm, no time for pics, sorry. Maybe later if I can find the time.

Top, the bit you touch, is grey & curved on these. plastic hinge pin either side, just ease them clear - no springs to fly out.

Below that is the blue, middle section. Below that is the white block with the connecting pins. After you've unplugged it from the harness.

Problem on mine is in the blue section. Of the 2 upright spring-loaded pins (diagonally opposite corners) one is sticking. Guessing that's all it would take to blow one or both 7.5A fuses - up and down switched on at the same time.

To separate the blue section from the white it looks like I need to desolder 2 massive solder blobs from the little (10 x 25mm) green circuit board - being careful of the 2 smt components - before the barb-locks can be prised apart.

Obviously easier & cheaper to buy a new switch but I'd rather fix it tonight if I can. Tomorrow if Deadwood's on at 9.
And yes I am a tight old git.

BTW removing the n/s switch & replacing the fuse allows the o/s switch to work both windows as usual, confirming the diagnosis.
edit: confirming my own van's diagnosis that is of course - not yours!

got the window to work there was 2 wires cut and going to earth on the drivers side door where they come out of the rubber boot and go to the body. also there was a live feed all the time to the down side of the switch in the n/s door

Good result mate
