help!gl450 2012 front wipers not working, I checked the hood switch and it works I even bypass it and nothing, I recall getting the hood open alarm and went away, wonder if the code got stuck and wipers are blocked,

If it work prior to your hood alarm then it could very likely be a stored and active code. If you don’t have access to an MB star system removing all battery voltage from the car for a short period should do a code reset. Nothing should persist after that until you actuate the system again.

DIY 101: check the fuse(s). Fuse 100, 30Amp in engine compartment, and Fuse 60, 5Amp in trunk

Thanks, temoves the battey for 20 mins, checked those fuse and they are ok, but there is no voltage on them when wipers are on
I did put it in Reverse and the rear wipers go on so its not the column control
I think the hood open code still there blocking the front wipers
any other idea? or someone in the SoCal area with a good scanner who can help me
taking it to the dealer will cost at least 240 for inspection

If the hood is open the wipers are disabled by the controller as a safety feature so if the hood open icon is lit, then the wipers will not work.
First place to look is the hood open switch.
