Your Chevrolet Avalanche offers a great mix of utility and comfort. But, your comfort during cold-weather drives takes a hit when your truck's climate control system isn't working the way it should. If your Avalanche's windows are fogging up for no reason, you may have a malfunctioning heater core – a key component that permits your heater and defroster to function.

Other symptoms of a bad core include, a sweet smell inside your vehicle, coolant pooling on the passenger-side floor and very cold or warm air coming from your heater. AutoZone carries Avalanche heater cores to get your heater working correctly again.
