C70 Passenger Side Electrics
I've just checked and can't see a specific C70-related thread on this, but did find a few S40 and V50 ones...
....I've started to have an intermittent problem with the passenger side windows, and also the central locking (and the BLIS) on that side. The problem only comes to light when closing the door - because the window hasn't 'dropped' slightly as it should, it sounds different on closing, alerting me to the issue, as the window (and therefore door) isn't closed properly... ....it's now happened twice - both times at home, fortunately, the first time on getting back, the second when about to go out. After 5-10 minutes of trying the various control switches, turing the car on and off, and (carefully) opening and closing the door, it's suddenly 'cured' itself... ....the S40 and V50 threads describing similar problems make reference to a connector inside the door, and suggest spraying with WD40 - so the main thing I need to know, is how do I find and get to it in my door? Can't find a Haynes for the second-generation C70... I'm also confused as to why the rear window is also affected, when that's part of the main body, rather than in another door - it has its own separate fuse - or is its wiring routed through the same connector in the door? TIA

Hi Andy
Where all the electrics go into the door from the body, is a plug/socket, partly obscured by the door stop. It's that piece that wants spraying, the issue I have is that the window drops but doesn't go up when the door is closed, unplug it and give it a spray (WD40/Contact Cleaner)working again until it may need another spray. I haven't had to disconnect the battery but it may be an idea. Hope this helps. Fred |

I shall endeavour to locate it tomorrow in daylight (and when it's not raining)... ....I'm relieved that it sounds like I won't need to remove the inner door panel - had to do that once on the S40 to replace a window motor, and never managed to refit it as snugly as it used to be!

Technically, the front window motor's electronics module receives the control signals for both front and rear windows on that side from the cars main canbus connection. The front window module then passes the control signals for the rear window via a dedicated linbus connection to the electronics module on the rear window motor. |

....but the above's good to know - I'd have probably been cursing while trying to pull it out straight!

So, the good news is I've successfully identified the connector I need to open up - the bad news is, I cannot pull the top locking bit up to get the plug out...
I found this short Youtube clip showing the C30 equivalent: https://www.youtube.com/watch?v=KP4x7yqdDYY However, lifting the locking part isn't as easy as it says - I can pry the visible side up about half-an-inch, but that's it, as I can't get anything into the other side to pull it up... ....further suggestions welcomed!

Hi Andy
It is as easy as the video makes it look, the part that slides up s/b one square covering the top of the plug, front & back. It only raises about a half inch but doesn't come off the plug. Once fully raised the plug can be taken out of the door, apologies as I do find it easier to remove than to explain how to remove the plug. Fred |

Cheers, Fred
I'll give it another try tomorrow; my problem is that only the side which I can get the screwdriver head into lifts up - the other side which I can't access stays down, leaving that top part sitting at a slight angle... ....think I'll try to find something to 'hook' into the other side...
