Cruise control doesnt work the light doesnt even come on

Fuses are a great place to start, if not fuses the actual cruise control switch may be to fault. Rear heater do you get heat out the front and if so is there a fuse for a rear fan maybe a blower.. Let me know

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.

2003 Nissan Altima Heater problem

car heaters work by recirculating the heat from the engine coolant, this problem sound to me like you have a faulty heater matrix, these are generally a pig to get to and even more of a pig to remove/replace & involves a lot of stripping out of the dash, if you really want to do it here are the instructions on how to do so......

  1. Removal
    • 1

      Make sure the Nissan Altima's front wheels are in the straight-ahead position. With the ignition off, disconnect both battery cables, starting with the negative. Wait at least 10 minutes for the air bag's energy to deplete before continuing.

    • 2

      Detach the driver side air bag and steering wheel. Disconnect the air bag module connector and horn electrical connector from inside the wheel's lids. Use a T150 wrench to remove the bolts Store the air bag module face up.

    • 3

      Take out the passenger side air bag. Remove the glove box to reach the module connector.

    • 4

      Jack up the Nissan Altima and securely place it on jack stands. Place a clean container directly underneath the drain plug located on the bottom of the radiator on the passenger side. Carefully remove the drain plug and drain the engine coolant from the cooling system. Put the drain plug back in place and set the coolant aside.

    • 5

      Discharge air conditioner refrigerant. If your car used R-12 refrigerant, it's against the law for you to discharge or recharge the system unless you're an EPA-certified technician, so you may need a professional to do this part. Disconnect the heater hoses from the heater core tubes from within the engine compartment.

    • 6

      Remove the instrument panel from the car. Remove the lower panels first starting on the driver side. Removal includes all the screws and connectors, the audio/deck pocket, switch panel, center console, grilles, pillar garnish, instrument stay and steering member. You may need assistance taking the panel out.

    • 7

      Disconnect the air conditioning housing by taking off the refrigerant lines and thermo control amp. Remove the heater unit from the car and the heater core from the unit.

    • 8

      Install the replacement heater core to the heater unit. Replace the heater unit and air conditioning housing within the car, reconnecting all the lines.

    • 9

      Reinstall the instrument panel, including the steering member, instrument stay assembly, pillar garnish, grilles, center console, switch panel and audio/deck pocket.

    • 10

      Reconnect the heater hoses to the tubes. Connect the steering wheel, both airbags and the glove box back onto the car.

    • 11

      Fill the cooling system. Use new coolant, if you're not certain the old liquid is still good. Recharge the air conditioning refrigerant (unless it requires an EPA-certified technician). Reconnect both battery cables, starting with the positive one.

    • 12

      Run the Altima's engine to its normal operating temperature. Check the climate control operation and inspect the system for leaks.

      If you do not want to go through this hassle you have two other options:

      Option 1 pay for a mechanic to do all of the above.


      Option 2 buy yourself a 12v plug in ceramic heater or two, one you could keep on the dash for screen clearing duties & another you could keep near or on the center console for body warming duties!, best of luck & i hope this helps.

The heater in my car will not work while in park or idling. But, as soon as I put my foot on the gas pedal, my car instantly blows hot air. But, if I stop at a red light, or if I place my car in park, it...

I have the same problem. When my dealer changed my coolant I now seem to have a stuck thermostat. They are denying they did it. I haven't changed the thermostat yet but that is the problem.

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.

Heater blows cold air at low speed and idle 02 nissan altima

I worked at a Nissan dealer for 18 months and we'd get a lot of these in. The cold heat at idle is accompanied by a sloshing noise from behind the dash - you've got an air pocket in the heater core. What we used to do was lift the front end of the car about 3 feet off the ground using the hoist and take the rad cap off. Then we'd run the engine at a fast idle (jam a screwdiver against the throttle stop to hold it fast or put a slight weight on the pedal if it's Electronic Throttle Body. Run the heater on full heat and the engine like this. You'll see the rad 'burping' as the air in the cooling system travelling to the highest point it can - the open rad cap. Top up with a 50/50 mix of coolant and water as you go. When it burps no more, you have a full cooling system and should not suffer any more "cold heat".

If you do this yourself, PLEASE use jack stands, block the back wheels and put the parking brake on!!!

Nissan Altima no cool air blowing or hot air blowing

It appears we have an Air lock scenario and you will need to perform a system Bleed.
Park the vehicle on level ground, when cold remove coolant filler cap, start engine and leave to idle, turn heater on full and blower to max. When engine reaches operating temperature watch and listen near coolant filler, keep clear as gurgling and hopefully a boil over should occur. Top up with very warm coolant and wait as it may do it again.
Check for heat inside vehicle if warm replace coolant cap but keep an eye on temperature gauge as the ~Air lock may have moved on from heater matrix/core so proceedure needs to be carried out again from COLD.
