Hey all,

The weather is getting cold. Today I turned on my heater for the first time for the season. Much to my dismay, I discovered the heater only stays warm for about 30 seconds then the fans blow cold air. I don't think its thermostat related because my engine temperature stays normal. Any suggestions?

Thanks!

Is your coolant low?

Sounds like a clogged heater core

Yes it was. Holy crap!! I looked and the reservoir was completely empty. Glad I (or you) caught that before something exploded. I filled it up, everything works fine now. Thanks!

Wow, be sure to check your radiator cap, radiator, water pump, and hoses for leaks. Watch the level in the coolant bottle over the next few weeks too. The coolant does get to be a little low over the years because of slow evaporation, but it shouldn't go down that fast!
