I have an 86 300E and I just ran into some wires that go up to my washer fluid squirters. Why do they have electrical wires going to them?

Ice heaters

Would you happen to know what turns them on and when?

There is a change on that info..

S26/1 temp control did not come into production until 1988 on 124 chassis.
So, your '86 version would have constant heaters when key ON .
[ unless it was upgraded..........]
Cut-in on S26/1 is +5C, cut-out is +15C..................
