Hi, having a few electric window problems with my z!, they work once or twice when i first start the car if i havent used the car for a few hours.

 

they both fail together, or work together.

 

is the windows relay'd somewhere, ive looked under the bonnet but cant see any relays for the windows ,and in the car!

 

anybody help on this?

 

thanks

theres a window 'amp' in behind the drivers door that packs up often! the soldered joints inside crack up.

ok, does this control both windows, is it repairable?

ive got a window amp knocking about somewhere if you need one

ok, does this control both windows, is it repairable?

 

yes and yes if you can solder, though for the price of a second hand one its possibly not worth trying.

 

the biggest problem is usually having to have the window down to get to a screw to get the door card off to fix it to open the window.....

Tech thread I did some time back

Drivers side window issues? the window power amp controller has a habit of failing leading to an intermittent or non working window, lucky it is a very easy fix and free to boot if you can use a soldering iron.

 

The unit in question is fitted in the drivers door, it is held in place with a single 10m bolt and has one 8 way connector plugged in to it, roughly just off central towards the rear of the door.

 

Once removed the outer case needs easing off the lower connector area, the internal part then slides out in one piece.

 

Photo 1 shows the internal parts of the unit and the pcb its all mounted on removed from the outer case, the two relays to the left are the output up and down for the window motor and the steel busbars to the right are the connection interface to the door wiring loom and the source of the problems.

 

Photo 2 shows the unit end up where the connector goes in and again the source of most issues the unit suffers from.

 

 

 

Photo 3 shows the rear of the pcb and the area in red is where the connector busbars are soldered to, not easy to see the problem yet.

 

 

Photo 4 shows the problem in clearer detail, the pin solder has failed and this is the cause of the intermittent or no connection and the failed window operation.

 

 

Photo 5 shows the method of repair, by applying a soldering iron to the effect area the solder will reflow and make a new connection.

 

 

 

Photo 6 shows the final result, a nice solid connection that will get that window operating again, just put the unit back together and refit to the door.

 

Happy fixing :D

ive taking mine apart an cant see any broken joints, so think i'll get a second hand one.

thanks for your help, mine indeed have the problem above, i just soldering it up, and all other dodgy looking ones but same fault, the little gate things making a high pitch sound and move up and down fast but no moventment in window.

 

also the amp do smell of electrical burning, so i need i new one, anybody on here have one for sale, posted via paypal please

 

cheers
