Well that was a tiring day, I started well with poached eggs and bacon on home made wholemeal
Then got my things together and started on the non working windows.
The passenger side rear was easy enough to solve, there is no mechanism, nothing, no wires / motor the lot, gone! So I need to get a replacement for that, do I need a year / mark specific one?
Driver side front was easy to diagnose, wire dangling down in the door, motor whirring away. Standard XM broken control cable then
I wrestled with the whole assembly, and eventually got it out but crikey, it was tough! I did not get many pictures as my hands were filthy, but it was quite odd as the door was totally dry apart from the gearbox which was soaking! Very strange?
When I disassembled the gearbox, it actually made me laugh, it looked like a ball of wool after our two whippets have been at it
Clearly the rusted / frayed / broken cable has been wound round and round doing some proper damage. The gearbox seal has suffered with the cable tearing the face off it and the compression spring.
I cleaned this up, trimmed the rubber back so it was neat and removed the spring, it is not perfect but it will do.
Next up was the cable drum, ooooooh what a mess!
The cable has abraded the nylon quite badly, distorting it and losing the definition on the tracks. I got out the needle files and tidied this up, did the best I could and it works, I am just not sure if the cable will jump tracks?
I built up the assembly using an ecrofting kit, I know they cost a fair amount considering the contents, but it is all there and a proven solution. Re-assembled and fitted the lot
This is where the car really stumped me, when fitting I tested the window at the earliest opportunity, fine and working well. So I continued to fit the door card and associated items, then a very odd buzzing noise emanated from the engine bay, and everything stopped working. I panicked assuming that something had gone properly wrong as my battery charger popped it's fuse too, maybe the motor had got stuck going up and had started to draw a big current?
I thought for a bit after I disconnected the battery, put the terminals back on and voltage checked the system, 7 volts across the terminals! I had flattened the battery and when it got very low obviously demanded too much off the charger, hence the fuse going pop. I put the battery off the BMW on it and all back to life. Still not sure on the buzzing from the engine bay though?
I celebrated by trying a bit of compounding on the front wing -
Coming up quite well I think, the paint is in good condition, just typical haloing and surface scratching. It won't take too long to sort out!
Thats it for today, we will be a bit quiet in the week due to dark, will be back on it again next weekend
Thanks guys.
