tip on winter pre like windshield , wipers & fluid free of ice.

And often times it is the spray nozzle that gets frozen over with ice, even though the washer fluid is fine.
A butane torch lighter can clear that up, if it isn't too windy.

Gently, though. Don't want to melt the nozzle or lines in the process of clearing the ice.

 

Neither have I with my 780 because the AC automatically kicks on when in defrost mode. When I had a 2018 cascadia as a company driver, the AC automatically went off when putting it to defrost. Bonkers!

 

Never had a heated windshield, but I've had some luck pulling the visors down and cranking the defroster way up. It traps the heat to the windshield. You will have to open your window or you'll be sweating your balls off.

If it gets bad enough though it won't help much.

 

Use the sleeper heater for you and the AC for the windshield. Let the snow slide off. Keeps from having to use the wipers and having the snow ice up the windshield and wipers.

 

Couple oz of simple green mix in regular washer fluid helps with salt and calcium chloride.

 

as others have said, heated wiper blades. These are the only way.

I get good results with a couple of ounces of Fabuloso. It works great on bugs in the summer, too.

 

get a reel of washer hose. then wrap it around your upper radiator hose, around the washer tank, several times. as the engine warms up, so will the tank, keeping that fluid warm.

or, wrap the hose around the outlet nipple of the tank, then to the spray jets, for a warm wash.

also, use a mix of washer fluid at least -25 and one bottle of rubbing alcohol in the tank.

 

I'll have to try that. Bugs get pretty thick in the summer around here. Thanks.
