Sounds like the Thermostat may be stuck in the open position. Hurry and replace because this condition will cause your water pump to fail shortly after. Cold air was my first sign and because I didn't replace it, I'm now replacing the thermostat, water pump, timing belt and balance shaft belt(because they got wet when the pump went out). $250.00 doing it myself, approximately $670.00 at the dealer.

I have an 03 Galant and when it started blowing cold air it was because of a defective cut off valve in the metal heater line just outside of the heater core. The design of the A/C and heater system places them together requiring that hot water not flow the heater is not in use. It is located next to the glove compartment and will require the removal of the dash pad.

I had a similar problem with Chevy Lumina when the thermostat went out. It was stuck open so the car never got up to a temp high enough to blow hot air. Kerry

10 w30 is a good weight as long as it isn't to cold

the most common cause of this is your engine coolant may be low. If this is the case then there is not enough of it to pump through your heater core (the coolant is hot from you engine, it is pumped though a serise of tube-like things similar to a radiator and then air is blown across it to make the air hot). That or your heater core itself may be broken in wich case it cost about 100-200 with labor to get a new one.

newer galants have electrical speedometers,have had lots of success repairing them by removing and resoldering connections for COLD solder joints. REMEMBER to DISCONNECT BATTERY before you do this!

it is not a thermostat problem is an actuator located under the dash that lets the water pass through the heater core, all these cars got the same problem dude good luck... Possible the thermostat installed upside down. Spring goes toward engine. Also may be air in the system. Bleed the cooling system with the heater set to hot. The heater core may also be stopped up.

It doesn't really blow it out it just warms the cold air.

Blow! Because if you blow your nose you are getting rid of all the rubbish in your system and will get rid of your cold quicker.

Most likely cause is low coolant. Check your antifreeze level.

We just put a new cd player in my daughters car. we had it done professionally but now we have no heat coming out of our heater, just cold air. Do you think they did something wrong? Could it be the blend door

You should blow your nose when you have a cold because it can stop you from breathing and it can make your nose run

Blows cold air through the heater. Overheats. Bubbles/oil in radiator. Check spark plugs for condensation on plug tips.

Generally, when a car starts hard in cold weather, it means that in needs more fuel than it otherwise would in a warmer environment. The amount of fuel provided to the car relates to the car's coolant level; so, coolant levels should be checked and replenished as necessary.

No, not if it's on a heat setting. Most home thermostats have a "Fan" setting that will blow cold air if the attic is cold.

If it does blow just not cold air you should see if it needs to be recharged

A simple way to check the air conditioning on a 2003 Hyundai Elantra is to turn on the unit in a car. If the air will not blow cold or at all the an the AC system will need to be looked at.

When you huff at your hand, that's 100% hot breath hitting the hand. When you blow at your hand from a distance, a lot of cold air is mixed in with your breath.

It uses a cable to change from heat to cold, it will start sticking and then eventually get stuck. Be careful not to break the switch, it costs around 400$ at the Mitsubishi dealership for them to do the repairs. You have to get in behind the dash and lubricate it, which can be very tricky.

Probably need to add antifreeze. Check the Radiator not the overflow tank. If you are low on antifreeze it will not circulate through the heater core.
