I've checked the coolant levels and replaced the thermostat. I dont think it's the heater core because I havent had any coolant leaks and my cab doesnt smell like it. The only other thing I've noticed was near the end of the summer I noticed water vapor coming out of the vents when the AC was high. Any ideas? Thanks!

Get the engine to full operating temperature and then locate the 2 heater hoses where the go into the firewall and see if BOTH of them are hot to the touch. Let us know what you find.
