I have water coming in to the passenger footwell when it rains. It’s def not a blocked/clogged AC drain. Not a leaky heater core. And the car does not have a sunroof.

It seems that water is leaking into this cavity under the A-pillar, and when it fills it up it flows out of the holes that have two black plastic anchors/connectors (circled).

Does anyone know if that area can be accessed from the outside? Something connected to those holes but what? Could it be a leaky windshield? I replaced the wiper cowl thinking that was the culprit but it’s still happening.

Any and all info would be super appreciated. Thanks!

I’m getting my 2020 Chevy Malibu LT 1.5L ready for a move to Fairbanks, Alaska. I bought the GM Genuine engine block heater (Part #[12586687](tel:12586687)), but I noticed the heater itself doesn’t appear to come with a power cord.
Does this block heater require a separate GM cord? If so, what’s the correct part number?
Also, if you’ve installed this heater yourself, how difficult was the installation? Did you have to remove anything besides the splash shield, and is it worth doing myself or should I just have a shop install it?
