heater blowing cold air

[g0ofy504]

takes about 30mins to defrost windows and get a little warm what do u guys think

Check your coolant level, if it's ok, either a bad t-stat or a clogged heater core.

def, either low on coolant, bad heater core or thermostat.If the heater core is leaking the passenger side floor should get wet.

No need to wait a week.
There's a plug at the bottom of the radiator (engine side).
Unscrew it a bit, and it'll start draining out.

I am currently in the same situation. I am going to check the heater core tomorrow. As for the other possibilities the thermostat, the heater control unit, or the Mixture Valve in the firewall (

Move to TX!

I say its one of the thingies that your box controls... either a knob or button...

Maybe flush out your coolant and winterize your car will help.

i had a stretch in the cable that switches from heat to non-heat ha
i just have to manually open the thing at the firewall, sorry my heater terminology isnt better

Drain water out? Are you running pure water? If so, that can cause corrosion... and that will clog things.

That, or have you ever added any stop-leak crap to your cooling system?


The heater core can clog easily. No heat is a sign of that.

Hey, someone else in Houston.
A little off topic. My heater knob is stiff when turning hot to cold or cold to hot. when I worked at Honda, most CBs and CDs were like that. Not sure if that's just the norm, or if there's a fix for it?

ok i drained the water out about a week ago and its working a little better but still taking w a while to get warm it takes for ever to get hot so am going to change the t-strat now and after ill know its the core prob is now but atlease ill have a new t-strat

Hmmm what is your temperature gauge telling you? It shouldn't take more than 3-10 minutes to get to full temp... depending on how cold it is outside. If you are in NO than you should be getting warm in 1-2 minutes. I bet it is some mechanical thingy in or lever. My knob that controls heat is very stiff too.. I think that's a good normal sign... if it isn't stiff then you probably have an issue.
