Burn smell after cleaning wiper blades and windshield?

Depends on if you were applying fluid just like it was raining. The constant flow acts as a lubricant and coolant as it goes over the glass. Clean glass and blades will have friction that generates heat. The heat makes the blades smell like hot rubber. It won't hurt anything unless you keep doing it. That could damage the wiper blade's edge.

You wouldn't smell the pump; it's buried behind the fender. It is just the blade friction. Just don't keep doing it, the heat can damage the blades. The other car likely has different blades and some dirt on the glass.

There are still a lot of differences you don't see. The blade pressures, the actual angles on the blades, the blade composition, the wiper fluid itself. There really isn't anything to worry about.

I mean it is nothing to worry about. The wipers are not the same, there are springs that hold them down that can be different, the angles of the blades on the glass can be different. Even the temperature of the glass can cause differences.

It should but it depends on the washer fluid, most of it is just water and alcohol and neither really acts like lube. But let us know what they find.

Well mold smells strange and combined with the alcohol and water it could smell worse. If the smell is gone then it might have been mold. Without smelling it myself, I can't really say. But as it's gone now it's possible.

Guess it depends on the species of mold.

Scents can be tricky to pinpoint. Sound and smell are both like that as your mind is only familiar with certain ones as you grow up. Both can fool you.

They cleaned the mold and the smell is gone? If so, it was the mold. I figured it would be the blades because of the rubber smell, now if you were parked down the road from a race track or a place where there was street racing you could have smelled that, but in those cases your nose would have said, ok ears hear a roar and nose smells burnt rubber, that is from the street racing. For me I need to think about what could cause that smell and what was happening at the time. There is no real rubber in the system other than the hoses and blades. If it was electrical or even overheating you would know it, that smell isn't anything you would forget, and it doesn't smell like rubber at all. It is an acrid stench that just hangs in the air. In this case the mold removal removed the smell. If that wasn't the cause it would still smell.
