V70 electrical issues
I've just got myself a P1 V70R :teeth_smile: it has a couple of electrical niggles, the drivers door doesn't unlock with the fob, you can see the button pop up, but I have to unlock it with the key to open the door, secondly, the rear wiper isnt working
The guy I bought it from said, it must've just happened :rolleyes: but he would say that ! Everything else is good, drives great. |
Hi forbsie
Sitting in the car (with the window open) if you lock and unlock using the lock button on the drivers door switch pack does that lock and unlock any differently from when you use the remote? If you remove the door card, you might find that the wires to the lock have been disconnected, presumably for a reason. Until you have sorted the locking problem, a safe option is to leave the door card removed, because it gets difficult to remove it if the door is stuck locked. Be careful when you remove the card because good ones are very hard to find. Does the rear wiper attempt to move at all? Rear wipers sometimes fail because the shaft goes through a black grommet in the glass, and corrosion on the shaft seizes it up. You have to remove the tailgate inner panel then you can see the wiper mechanism. Buy a new grommet from Volvo, take out the old unit, clean up the shaft and see if it works then. Measure voltage at the wiper when you try to operate to find out if there is a supply problem. Sometimes the wiper doesnt park correctly. Can be caused by burnout of components (resistor or capacitor on the wiper itself). Fairly easy to get a good used wiper. HTH Steve |

When you say use the lock on the drivers door switchpack, what difference could there be ? using the fob, all lock pins pop up ! is the door card held in with screws or is it clips that you just pry out ? |
Rear wiper - There maybe a broken wire in the harness adjacent to the hinges. See RobertDIY on YouTube for panel removal Not too difficult if you follow the right method.
He also has how to's on door card removal. |

Also this...
https://www.pelicanparts.com/techart...eplacement.htm but I'd follow Dereks suggestion and check for broken wire at the tailgate hinge area, not an uncommom problem...try removing tailgate panel and checking for supply voltage at wiper motor |

is there a fuse for the rear wiper ? I cant seem to find it in the main fuse box ?
|
Might be fuse 33, headlight levelling & rear wash wipe
Can't seem to find one for wipers in Haynes manual |
Hi
If it turns out to be a seized wiper motor shaft, this how-to article shows a lot of useful info https://www.volvoforums.org.uk/showthread.php?t=46955 HTH Steve |
