    Default 2001 Suburban A/C smells like anti-freeze

    I noticed the other day when I first turn on the A/C that I get a coolant/antifreeze smell but after I run the AC run a few seconds the smell goes away. Anyone have an issue like this?

    You probably need to replace your cabin filter that is located under the dash on the passenger side. If you have never changed it, be prepared to see an abundance of debris!!!

    Check for a wet rug under the passenger side dash if the rug is wet you might have a heater core leek.
