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

Hi Middle line in rear screen works when demisting (frozen window this morning, so a good test!). All the others do nothing. Any ideas on cause? A cursory glance didn't reveal any obvious broken lines that I could see.

POST 2Original post

Failing battery and the car ecu limiting power drain?

POST 3 / ORIGINAL POSTEROriginal post

Rest of car is fine, no known battery issues, starts on the button etc. Given one line does work, I am assuming some break in delisted circuit somewhere, or connector (not sure where that is) has bad.loose connection?

POST 4 / ORIGINAL POSTEROriginal post

Forgot to update, a new rear screen went in a few months ago. Dealer/warranty contributed so didn’t cost me too much but only option is genuine rear screen, no pattern parts really… Anyway, all working now, was just aged/broken demister lines.

This is a source reference. Confirm exact model applicability in the original material.
