Smell from vents!!!

[Prince95GT]

I seem to have a very weak smell of coolant from my vents when the a/c of heat is on. Anyone know why?

Well, it very well could be a bad heater core. Is your windshield fogging up?

 

[Prince95GT]

The windshield doesn't fog at all. The smell though is extremely weak sometimes not noticed at all..

check under the passenger side dash. see if there is anything possibly leaking under there. Sounds like a bad heater core.

Yeah, sounds like a bad heater core to me. Mine leaked on the driver's side near the accelerator pedal. Look behind the dash there and see if you feel coolant fluid.
