Read evidence and context

Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Discussions that report a fix: 1

1 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

So we changed the wiper relay and the problem seemed to go away - until this weekend, where it resurfaced during the torrential rain. I'm pretty sure its not meant to be a rain sensitive wiper (!) and I've got a sneaking suspicion that in heavy rain water is getting in somewhere (not that I can obviously see though) and interfering with a control circuit - my reasoning being that once the rain stopped and the car dried out the problem went away.

Suggestion · Original poster
My rear wiper was intermittently problematic when I bought the car 5 months ago, and instead of doing 3 sweeps when you press the button, it would run on for a while, often not cancelling until I turned off the ignition, and even then it would sometimes start up of its own accord.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Now you can't have a Monday without one of my posts - so, this is what I discovered this weekend. My rear wiper was intermittently problematic when I bought the car 5 months ago, and instead of doing 3 sweeps when you press the button, it would run on for a while, often not cancelling until I turned off the ignition, and even then it would sometimes start up of its own accord. So we changed the wiper relay and the problem seemed to go away - until this weekend, where it resurfaced during the torrential rain. I'm pretty sure its not meant to be a rain sensitive wiper (!) and I've got a sneaking suspicion that in heavy rain water is getting in somewhere (not that I can obviously see though) and interfering with a control circuit - my reasoning being that once the rain stopped and the car dried out the problem went away. Also (not sure if this is just a quirk), I notice my wiper only wipes twice when you press the button, but the manual says it should wipe 3 times (go figure?). Any thoughts or experience please?

POST 2Original post

Mine only wipes twice, never really noticed it before but just thought I'd check for you.

POST 3Original post

Ive never used mine, Why would you need too? Been thinking of taking mine off.
