Exclamation Start with partial electrical system and wipers on...

2012 Grand Cherokee with key start and remote start has failure in which on start the windshield wipers activate and part of the electrical system does not energize. Turn signals and quad transmission selector is not energized.

Amber stability light and engine light are on.

Conditions change after 5-8 minutes. Windshield Wipers stop and electrical system fully energized.

This also affects remore start feature, Remote start will start Jeep, but it aborts after about 10 seconds.

This can also happen when Jeep is being driven - partial electrical shut down and windshield wipers start.

Re: Start with partial electrical system and wipers on...

This sounds like a bus problem... when messages dont get where they need to be modules go into a safe mode where where they figure things like, they would rather have the wipers going and it be dry than no wipers and its a downpour... This is going to need attention from the dealer, sorry.
