Wipers won't switch off

[DetectivePenguin]

Hi all,

I've got my 182 back from the paint shop and the wipers now won't switch off.

Any suggestions on what maybe broken or need adjusting.

Knackered uch?

 

[DetectivePenguin]

I replaced the uch in May, hopefully it's not the problem.

Could they have put the mechanism on incorrectly?

If you disconnect the battery they will stop - hth

 

[Mr Trailer Man]

What were they painting and what was removed?

Windscreen come out? Maybe related to rain sensor

Windscreen was out for the refurb. It's a trophy so no rain sensor thankfully.

Latest update.

After disconnected the battery, the intermediate setting has stopped working and the wipers remain on for 1-2 minutes after turning them off.

We disconnected the battery again and the wipers now stop when you turn them at their current position and don't go back to their starting position.

The wiper motor has a park switch inside - could that be buggered

Turns out it was yet another dead UCH. That's three in one year now

 

[Matt Cup]

Third time lucky 🤞

Can you send the duff ones off to be repaired?

Already done. £45 for a refurb is definitely worth it.

That is mental. Id had that full uch and ecu kit in my car since new and never had any issues.

You sure you're not chasing an electrical fault somewhere else that's killing UCH'S?

 

[DetectivePenguin]

When I first bought the T, it had a dodgy ground that caused endless alarm issues. I spent ages replacing all the grounds, cleaning connectors, and eventually swapping out both the ECU and UCH. After that, the gremlins were gone.

The T has just returned from a two-month, back-to-metal and glass-out restoration. I’m crossing my fingers that a small amount of water leaked through the top of the dash and I'm not about to start another electrical mystery

That'd be crazy though.

Have the same issues where did you get the uch repaired please

My intermittent & park failed recently.

Small hint of melted plastic on one of the harness side UCH connectors. Took it apart and found two female sockets melted together inside.

Re-pinned into a new (used) connector housing. So far working fine with original UCH.

I sent mine off to diesel pump repairs on ebay.

I have pink wear broken do you know where is goes please 🙏

I had very similar issues with a 182 years ago. Proper random electrical faults and bills for thousands in replaced parts. Stuck in limp mode.
Guy had enough and sold it to me.

Pulled the bulkhead Loom connector apart and it was a right mess In there. Melted wires galore.
Once repaired, it lived on for many many miles.

Definitely worth checking.

Where exactly is this connector? Is it behind the glove box with the other electrical guffins?

Guessing he means the one near the washer bottle.

Outside or inside the car?

 

[Mr Trailer Man]

Outside or inside the car?

Outside, under the scuttle.

Don't tend to see many faults with that plug tbh its well sealed.
