HELP PLEASE, front wiper problem losing my mind

[Mattcheese31]

ok so, phase 2 DT, wipers are only working on single wipe and position 2, they are not self parking either,
i have changed the wiper motor for a known working one and still the same, swapped the relevant relays (i think) and tried another working stalk, all no different,

what the fcuk could it be? i've run out of ideas and it's the wifes new car and she's going to make my life hell if i don't fix it . . .

anyone? . . .

if it has rain sensor there is two fuses and two relays to check

any idea which mate? i'm a phase 1 man so i'm in new territory lol, been at it last 4 hours, ffs

[Dum-Dum]

bad earth?

[cully]

F34 30Amp
F30 15Amp

[cully]

earth point for the control is at the bulkhead near the throttle pedal
earth point for the motor is at the o/sinerwing behind headlight

[Mattcheese31]

bad earth?

what, when it's working on one speed? . . . . .seems unlikely mate

F34 30Amp
F30 15Amp

cheers, checked all the fuses with a multi meter . . . . .


two of the relays i replaced one of each of the pins was burnt out with melted plastic on them, tried to clean the socket up with contact cleaner and replaced the relays but maybe not good enough??

anyone know what specifically controls the wiper speed? . . .is it the relay just sending more current to the wiper motor?
if so i guess it could be that . .

[cully]

the two relays control the speed by changing the motor internal wireing
the stalk or the auto wipe sensor switches the relays depending on the stalk position

Hello my wipers where parking anywhere also working on certain speeds. I tried the fuses and relays but in the end it was the wiper motor. There 3 pins inside the wiper motor once these break they start playing up.

Also any water inside or near the drain corrodes the wiper motor up to.

ok . . . . . . . . that's interesting, wonder why it doesn't park as well . . . . .you don't know which relays it is then? . . .at a guess i would say it's the two green ones to the left of the fuseboard but not sure.

you could still have issues with the sockets

yeah that's what i'm thinking now mate tbh, it's dark now though so have to resume tomorrow . . . .the car is looking like an electrical balls up, previous owner had wired the sub off the boot courtesy light the fcuking bellend . ..

just tryed to reply again but the bamn pc rebooted itelf

the motor stop is directly controled by the auto sensor box on the windscreen

[Dum-Dum]

I suppose the last thing to do (and possibly easier than continuing to try finding the problem) is to just rewire the entire front wipers sadly.

don't think it has auto wipers, what does it look like?

[Chris1357]

Was it the big Blue Relay at the rear of the fuse board that you changed Matt?

damn right the last thing . .

[Chris1357]

Yep big blue one mate, Got one here if needed Came off a Ph3 cabriolet that I broke.
£Free. can send it via work for nowt too.

[Toms306]

If it has auto wipers the sensor is located behind the rear view mirror, easy to see from outside as there a black 'lump' around it on the screen.




On the ph3's the wiper relays are purple but but may not be in ph2s!


Edit - The only blue relay I've seen on a 306 is for the rear wiper and that's not near the fuseboard!

Hey thanks fella but i've got an old 306 here that i'm raiding for parts anyway . . .respect for the kind offer though x . . .

[Chris1357]

Not to worry mate, It'll stay in the drawer until some else needs it.
take it out of the scrap car 1st as in some cases I have broke the face of the fuse board.

Ah, fair enough, just looked at the link you posted as well. I broke 2 this year...........but both phase 3's with auto wipers lol.

[Chris1357]

The cabs dont have Auto wipe, even on Ph3' But the the 2 hatches I broke did.
Auto wipers = more trouble than worth IMO, Horrid.

[Toms306]

I really like auto-wipers tbh, auto lights are even better, each to their own though!
