Why is this yellow fluid being expelled from side vent?

[rschap1]

My whole truck, especially the roof behind the sunroof has been coated with pollen and waterspotted looking a little like that.
So I don't think that question was too far out there...
Good luck with the find and fix

I have the same thing in the exact same spot on my Gen 3. Saw it yesterday for the first time while washing the truck. It wouldn't come off with water and soap. I'll try goo-gone. I don't think it's pollen either for whatever that's worth.

I also have the same thing on mine comes only on the left vent but pretty heavily.
Idk what it is it’s definitely not pollen.

It just needs cleaned properly, I bet you are not removing it when washing and it attracts dirt dust and also hard water stain on the sticky residue.

Just checked mine, truck is only 2 weeks driven and its there, not a lot and didnt wipe away

I wonder if it is some kind of adhesive leaching from the vent while sitting in the sun.

I'm thinking it is anti-corrosion grease from under the hood somewhere. German makes used to refer to it as 'cosmoline' years ago (they still might) and it was a thick, smelly grease in paste form. You'd get it dripping from body cavities on really hot days on a newer car. Maybe they overapplied it to your truck in some areas?

This...

My wife's BMW X7 had this...white truck and small yellow spots all over it. Especially prominent around the lower door areas. I believe it is some sort of sealant that is applied when new and it is very hard to remove. I live in Kansas and Oklahoma and know pollen...this is different.

Op, depending on how much you love your truck, this may be perfectly normal. Might I suggest keeping a terry cloth towel within reach for those times when you are really feeling the love for your Raptor.

You named your throw rag Terry?

OP, It looks like pollen to me too. It was a banner year around here for it, but that was a a month or two ago.

Where do you live? Is there dew in the morning? Water + pollen/dust = spots on shinny new gen 3.
FYI does not happen to gen 1s

I bet you have mice or rats.
