Window lift ecu rear windows

Tunatime123 · Jan 11, 2021

OK so my rear windows would occasionally work normal stop working in the ****ing down rain hahaha anyway I pulled the lift ecu found bad joint and fixed it. Tested before fitting and was Allgood reinstalled it and worked then didn't work wiggling the wires made it work. So I took it out again and checked connections and Allgood but when I moved the relay it would click on and off would that indicate that the relay is bad or what? I've checked the fuses as well and they allgood. Any help would be good. Thanks

To me that would suggest a bad joint on the relay coil side.

I have no idea what vehicle it is for, or how much electrical knowledge you have, but it sounds to me like a broken wire or dodgy terminal. The fact you said “wiggling the wires made it work”, would suggest a wiring issue. Also “moving the relay would make it click” suggest the relay terminals.

So I just used my brain clicking relay means bad connections...... I took the ecu out had a look at solder joints with magnifying glass and found some more cracks I couldn't see with me own eyes solderd them up and looked over the while board found some more cracked on the plugs coming in and sorted that out to and hey presto it's Allgood
