You might try bleeding air out of cooling system. Elevate front of car on ramps and leave running. Remove radiator cap before engine gets hot. When engine starts to heat up, air bubbles may come out of top of radiator. Add coolant slowly as level drops. It may take a long time for car to warm up (15-20 minutes)
have 2002 altima,blower works no heat at idle and very little heat when accelerating.I changed carbon cabin filter,made sure little gear under dash to temp knob wasnt broken,flushed and bled system.Nothing worked so checked hoses to heater core and found inlet hose was hot,outlet hose was not.So investigated this problem and came to conclusion heater core was clogged.An easy way to check is to get car to normal running temp. put on heater and blowers at full.Go under dash on passenger side where counsel meets firewall,this is where heater core core inlet and outlet aluminum tubbing go through firewall,you will be able to feel both tubes one closest to you is outlet, so if this one is not hot and and other is your heater core is clogged.I detached both inlet and outlet hoses to heater core from water control valve.Then I blasted water with waterhose and nozzle set at jet,first through outlet hose to blow gunk out,then through inlet hose until water runs clear.Reatach hoses fill and bled system.heater works great nice and hot!
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!!!
its most likley to be the engine thermostat you could need a new one fitted dose the engine get fully hot or dose that take a long time to warm up as well even when your driving it,, if it dose its that themostat
1) it could be that your air blend door is stuck or the gear that controls it is broken.
2) it could be a problem with coolant leaking or a coroded cooling core that causes its efficiency to drop to the point where when under load, the engine will heat the air in the AC system to only blow hot air.
The solution for the first problem is an relatively cheap fix. there is a service bulletin for it with the part number and how to check if its the problem on the nissan forums at nissanclub.
The second problem is rather costly and involves some wrenching,.... you can also find information on that on the forums.
Hope that shed some light on it, and best of luck.
appears we have an Air lock scenario and you will need to perform a
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
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.
