Question about Cars & Trucks
98 fird windstar 3.8 when i start my van in the morning to let it warm up it blows cold air even if its been running for 30 min. but if i drive it blows hot air after about 5 min. of driving just started without warning and i cant really tell the level of antifreeze cause the neck of the radiator is bent in tword the motor. do i go by whats in the overflow?
Fill the rad to total capacity, also your heater core is most likely "air locked" you nede to loosen the return line from the heater and with heat set to high and engine running, allow fluid to leak from the loose connection until all air bleeds out. since the heater is higher than the water pump it will not force it out on it's own. you could get a mechanic to do this for you but why waste money for a simple fix

The clicking noise is the door blend actuator. It is located in the dash panel behind the radio. It is about the size of a pack of cigarettes.
I priced this job at a dealer and it came in for around $300!
This is a really simple repair, a great choice for the do-it-yourselfer.

SOURCE: Heater blows cold air when idle
Sounds like you may have a partially plugged heater core. You could flush this out separately, from flushing radiator & engine block. Diconnect heater hoses going to your heater core and clamp off, so not to loose coolant from engine. Now hook up separate hose to one side of heater core pipe and flush out with typical garden hose. Repeat procedure on both heater core inlets. Reconnect original heater hoses and test difference. You may have to add an additional litre of antifreeze. If this don't work i suggest changing heater core. Good luck.........Ron.

If the blower is blowing air just fine, but you cannot control the temperature, you need to listen to air coming from the vents while turning the temperature from hot to cold. If you do n ot hear any change in airflow, then you may a temperature door in the dash broken. this is becoming a common problem on the Equinox and Pontiac Torrent,
