my heater decides to quit on my yesterday!! the fan motor comes on and blows cold air!!! lately ive noticed my heater core has been making some gurggling noises, but didnt think anything about it.... hum... i guess im goin to make sure its gettin coolant to the heatercore first, then tear into my dash.... any suggestions??

 

sounds like lack of flow of coolant through the heater core. the gurgling was air getting in there, most likely have air trapped in there, need to push it out. Your low coolant message isn't on in the dash? your temp isn't rising when sitting in traffic?
