Help!!!!!
Hi I’m new to the group, hope everyone is well!
My problem-We purchased a phev last year (2015) and it went for its first service with us at stoneacre Mitsubishi (big one, spark plugs etc) About 2 weeks after the wipers wouldn’t switch off? Been back to Mitsubishi for diagnosing - first time said it was etac board but would need further investigation poss wiring loom? Went back, said it was wiper linkage and would need to order the part, would ring when it was In stock, I kept calling to check as I found customer service rubbish! Called Monday and the wiper MOTOR had come in? So we booked in for today. Went into workshop, it came out still the same :( so they’re saying it could be the etac board again at £900 and they’ve washed their hands of it. Told us to get an auto electrician as they’ve don’t know what to do!!!!!
Can anyone help? I really don’t know what to do if main Mitsubishi dealer can’t help
Thanks

The wiring diagram shows that the wiper circuit includes the Rain Sensor Adjustment, ACC Relay 3, Windshield Wiper Speed Switching Relay, Windshield Wiper Automatic Stop Relay, all external to the wiper motor.

As they have replaced the wiper motor, which has an internal switch the opens when the wipers have parked, I'd start by pulling the Auto Stop Relay and see if it's jammed.

Can you still control the speed of the wipers? That may eliminate that control unit.

Thanks for your reply

Cannot really control the wiper speed-sometimes they just go on the fast speed whilst on the intermittent with no rain?
Not sure if they left the new wiper motor on today either as we wasn’t charged for any parts

Yes the rain sensor is sometimes triggered by dust etc. but also I have long had a wiper speed that doesn't always match need - very fast in drizzle or nothing in heavy rain. I just put it down to the sort thing that happens with ageing electronics. Does the manual control still work?

No it doesn’t, basically when you put the wipers on it takes 2-3 minutes after trying different settings to get them to stop which is not good when you just want to wash them but they continue to go and it’s dry

Clearly not the motor itself but a control problem - I'd suspect the sensor.

That was my initial thoughts but Surely that would have come up on the diagnostic when it went in and has been done twice apparently!!! Do you mean the sensor on the windscreen? I’ve blown it out with compressed air in case some dust was inside but made no difference.

Do the wipers still play up if you turn off the "auto wipe" feature using either the dashboard settings or via a smartphone?

Haven’t got an auto wipe feature on dash settings, how do you do it through smart phone?
