Guide: Replacing 306 Broken Door Loom
#1
Have been having problems with my electric windows and the electric mirrors, i noticed that opening closing the drivers door sometimes made things work
so i was fairly certain the drivers door loom had broken wires in the flexible bit between the door and A pillar

   

this is a guide on how i went about repairing my loom.

Choices i made before starting
Do i repair my current loom?
No as i only wanted to repair this once as it would take 2-3 hours

Do i use second hand parts?
the answer to me was to use new parts
the reasoning behind this is my car is a 2002 last of the 306's so any second hand parts would probably be in worse state than my loom

Do i use New parts?
Yes as i could justify the expense because i was saving on the labour cost by doing it myself

So a new repair door loom with plug was ordered from Peugeot
part no 6542 VQ Price £97+VAT retail i paid £79 total

today was the day i would set about my repair

Tools
Wire cutters
Wire strippers
Multimeter
Heat gun
Soldering Iron
Screw driver
Torch
Solder
Heat shrink
Cable markers
Spanners

   

first off i opened the drivers window opened the Bonnet closed the door and waited for the BSI to go into sleep mode then i disconnected the battery

   

unplug the door loom plug and compare it to one you are replacing it with
make sure you have the same pins or more

   

now to remove the door to gain easier access to the plug n wires,
unbolt the check strap and remove the 2 centre hinge bolts the door will stay unsupported,
try not to push the check strap into the door this will save you strugaling later
now hold door via internal handle and window frame and lift the door will lift off the hinge, place door down on soft ground to save paint damage

   
   

now you have easy access to the plug and grommet

gently prise out the grommet you will find it is a double grommet and the internal section has the rear water squirter pipe going through it,
you will need to cut the inner grommet to release the water pipe

note the Apillar bulkhead is 3 skins!

   
   

once i had freed both ends of the grommet i could then see my broken wires

   

as i was replacing the complete plug i removed each wire in tern and labled it with the plug pin position

   

now you end up with a scrap plug and the grommet which you need to thread onto the new plug n loom

   
   

good thing about a new loom plug is you dont need to lable the pins to wires as it is already done for you
see in the picture the wire numbers the number between the * is the pin number
ie: yellow wire *3* THE 3 IS THE PIN NUMBER

Now its time to get busy with the soldering Iron
But dont forget to thread the heatshrink on first!!

   

TOP TIP!!!!!
you need 3 hands for inline soldering get yourself some crocodile clips and make a 3rd hand!
now you can aline the joint hold the solder and apply heat

   

Heatshrink as you go

   

soldering larger cables

   

all done!
Tidy job Smile

   

dont forget to insulate the unused wires as you dont know if they are connected in the door side

now you have finished the soldering you might want to test your handywork
to see if you have fixed or caused more issus ! Big Grin

i brought the door to the car and plugged in the new plug as it was on a long lead
just to test and it all worked!

now you have to pull the cables back into the car and refit the grommet,
you might have to release the carpet on the A piller to enable you to pull the cables through, i also had to use a wire hook to reach up and pull them in as i couldnt reach the hole

   
   
   

now its just a case of refitting the door plugging in the plug and tidying up the wiring inside the car so you dont get your feet tied up

few extra pictures of the notes i made just incase the numbers fell off i put on

   

the drawing i had were 99% correct with just one wire number incorrect

   

to sum up!
the job took me about 3 1/2 hours in total
im glad i bought the new bits i wouldnt want to struggle with short secondhand cut offs,
would i do it again??? Yes I own a French car with crap electrics so i will probably have to!

if this guide helps anyone it was worth me doing it for you
so a little rep go's a long way Smile

good luck to anyone that attempts this

Did you find it easy enough to do by pulling the wires out a bit?

you wont pull any more wire out of the car as the loom it taped tight and runs up against the exit hole behind the fuse box on the A pilar

How would you go about doing it if the plug had already been cut off?

probably by doing what I'm going to do, go to the scrappy and cut a plug from a donor car to repair

But how would you know what wire coming from the car goes to what car on the plug?

you could always hard wire them, i plan on doing that to mine next weekend, doing away with the plug, add a grommet and have everything on bullet connectors inside the door

Wish I'd seen this guide before I started the loom on the estate.

Last night I missed the number on two green cable's, lucky I didn't blow anything and I realised that something was amiss.

Thanks for your help Cully.

Just looked on ebay, can get rear door looms for £9.99, but no sign of front looms...are these really a Dealer only part? Not sure im up for spending best part of £80 on a few bits of wire! Dodgy
