There may be confusion here as there is a button on the system labelled eco mode, but this is only on cars equipped with stop/start. The one which stops the engine mid install is the economy mode which switches off equipment to protect the battery. If economy mode kicks in you can ruin your system. Posts: 87 Threads: 18.

One wiper go in one position and stay there, another one just want to move, but nothing else. I take all apart but don't find fault. .
