HVAC System
Recently ive been having an issue with my hvac system. When i use my window washer fluid, i can smell it in air coming in from the vents. Same thing happens at stop lights cause my CCV vents inside the engine bay (gonna be fixed today). If anyone's got any ideas i would appreciate the tips.

Maybe the box holding your A/C evaporator coil is damaged or not sealed correctly? I did a video up a while back about how to get to the coil and remove part of the box. Maybe follow this and see if you see anything obvious.

What about the 1" black hose that runs from motor to blower housing, called the blower motor cooling tube... is it firmly in place? Or perhaps have a crack or hole in it ? It is a rather cheap hose and considering that it is like 20 years old.... check it out.

@Markus Luukko did you have some time to dive into this issue? If so, I hope you resolved it and that the video I posted was somewhat helpful.

I can smell the washer fluid every time through the vents if I am in Vent or AC. I believe they pull outside air from the cowl area in those modes.
In Max AC it only circulates cabin air and closes off the outside air. Perhaps if your smelling outside odors in all HVAC modes you have an actuator issue or vacuum leak in the system.
