heat fluctuates

[curtis5067]

Hey All, I'm new to board. I've owned an "04 SE for 2.5 years. It's got 79k miles. The A/C currently works fine, but the heat will fluctuate from blowing hot to cold regardless of temp setting, airflow setting or anything else. What's yall's guess and how much $$$$ to repair?? Thanks

Welcome to the forum... sounds like you may be low on antifreeze... check the level first.

How often do you check all your fluids????????????
Have you been having to add coolant or is your level real low in the morning before you start your engine?
As Joey said, you are low on coolant,most likely have a leak, which at your mileage could be something simple and more then likely head gaskets so have it checked ASAP and make sure to fill your coolant bottle to the lid, when cold, in the mean time.
