Heater core

[Bizcuit]

Good evening all,
I’m getting an antifreeze smell in the registers of my gladiator. I don’t get it constantly, but from time to time, and it seems to be stronger after I turn a corner. I’ve pressurized the system overnight, but can’t seem to find anything leaking. What seems to be even stranger is, it’s only in the driver registers. Can anyone explain this?

 

[jeeeep]

with the heater on, is it hotter air on one side versus the other?

The overflow reservoir is basically right there on the driver side firewall could it be overfilled? Or loose cap?

I’m not sure, I’ve only had it a handful of months so I haven’t tested the heat part of the system.

That’s a good point. Nothing is ever wet or stained like antifreeze is/was present. If you nose the register at the drivers door, it’s really strong, the number two register has a faint smell, the other two nothing. That’s the part that has me baffled is there is only one core to my knowledge. How is it only on the drivers dash registers. I’ve tried the dealership and they’ve said there is no common place to start looking. There is also zero videos on the Tube where someone has been there before so I was hoping someone here could help.
