Heater core may be partially plugged. Also check the heater control valve to see if it's letting water into the heater core.

2002 Nissan Altima Cold air blows at idle but is warm at higher engine RPM


Heater core may be clogged. Try flushing it to see if water flows through freely. Also check the heater water control valve for restrictions.

I have a 2002 Nissan Altima. The heat no longer works, it blows out cold air. The heat will only slightly work when I drive on the highway.


Usually it's a bad thermostat or a blocked heater core. The best way to fix it is to have it flushed out. But make sure when it's done, either by you or your shop of choice, they disconnect all the hoses and do the heater core, motor and rad seperately. Also put in a new thermostat. Another problem in certain vehicles with low use is that the air direction flaps in the dash are stuck. Start the car, and move the dials. you should hear the flaps/doors moving. (They are vacuum controlled, so thats why you start the car). I hope this helps.

Heater only blows cold air when idleing but blows hot air when driving at highway speeds. coolant level is fine.


you have air trapped in cooling system. Go to a shop that uses evacuate & fill equipment and have them flush system and burp air. SHould cost about $65. Make sure they have evac/fill equipment

2005 nissan altima heater blows cold air when stopped and blows hot air when going down the highway. What could be the problem?


Check your coolant level. If it is low, what you describe will happen. Water pump works faster as rpm's increase, managing to get hot coolant to heater core (highway speeds). At idle, pump is not working fast enough to get the coolant to the heater core.

2002 Nissan Altima - Heat doesn't get hot and doors get stuck


Did the switch break because it was stuck? If so, then yes, they will have to change actuators and doors. Does the fan work on all speed setting? If so then you do not need a blower resistor. The resistor pack only controls the current flow to change speeds of the fan.
