Hey all so I’m having a very strange issue. When I first open my car door in the morning and sit in the car (before turning it on) it has the hand sanitizer smell in the cabin. There’s no hand sanitizer or any other objects in my car. When I turn the car on and start driving I don’t notice any smell. This has been going on for about 2 months now. I opened the coolant expansion tank this morning and it’s completely full and the smell doesn’t smell like coolant. Anyone have any other ideas as to what could be causing this smell to permeate when the car is sitting overnight? Thanks!

Anyone have any guesses?

unless you got something uncommon, evap core leaking freon and crayon smell from insulation are most common.

Definitely not the crayon smell, I know that well. From what I’ve read, Freon doesn’t have any smell so I don’t know if that’s the issue. What would that smell like?

freon/freon oil definitely has a smell. you can quickly hit the port shraeder to see what it smells like or run a hose to the hvac/evap core drain to your nose

But I only smell this odor when I first open my car door. I’m not smelling it through the vents while I’m driving.
