Sounds more like the heater core is leaking. What year is your Blazer? There was an issue with some years, I think 2019 or 2020, but could be wrong, and a bad batch of cores.
Sounds more like the heater core is leaking. What year is your Blazer? There was an issue with some years, I think 2019 or 2020, but could be wrong, and a bad batch of cores.I noticed today after a 7 hour drive home today that my passenger floorboard was damp.
I only found it because i was sweeping the car out.
now what doesnt make since is i cant feel any dampness on the incline going up towards the glove box.
could the catalytic converts be putting off enough heat and with my AC running on the foot vents create a humid enviornment?
or is it my AC drain?
if it is the drain where the heck do i find it?
