Re: 2010 grand Cherokee laredo
Might be the multi-function switch going bad. This is the stalk on the left side of the steering column. Mine went out - lit the dash up like a Christmas tree, headlights wouldn't work, wipers wouldn't work, etc. Had no codes when the dealer scanned it - they had the vehicle for 3 days and couldn't figure it out. I read up on it on this website and mentioned it to the service manager - he said what the heck we'll throw one in and see - problem fixed!
