There is a heater control valve mounted on fire wall with a vacuum house connected to it, most of the time nissan heating problems is due to this valve being bad. You can open valve manually by moving lever to open position. and hold if heat come up problem solved. If not get back to me and I will be more than happy to help. Good Luck

No Heat


It Sounds Like You Have Either A Faulty Heater control Valve Or On The High Side A Bad ATC (Automatic Temperature Control). Check The Hoses That Go Into The Heater Core Both Should Be Hot At Normal Operating Temp. If The Outlet side Is cold Or Luke Warm You Have A Bad HCV.

Why would my heat start blowing cold


check you anti-freeze
is you car running at a colder temp it did before
what does the temp say
if the engine is not heating up to temp you may have a bad thermostat
if that is not your problem you may have a clogged heater core and need it replaced

I'm have problems with my heater. I usually blow very hot air and has always been a good heater. Lateley, it still blow air but seems to be cooler. Could it just be the thermastat?


First,check coolant level in radiator,if it is low you will have colder air on heat mode! Replenish as needed and in reservoir as well.Drive and test! Change the water thermostat if this doesnt help! Check water valve next,at the heater core inlet hose! The hose going in should be hot, and the hose comming out also,but not as hot. Check to see if the water valve functions or moves when you select heat from a/c mode! Is the vacumn line hooked up to the valve?

My heat is not working that good. When it gets colder outside and my car's temp gauge goes down, the less heat I seem to get out of the system. When the car is idling at a stop is when the heat starts...


Your thermostat is probably stuck open, not allowing the engine to warm up to its normal operating temperature. The coolant circulates all the time, so the radiator is constantly dumping all of that heat. Replace the thermostat, and your problem should get better. You may even consider installing a higher temperature thermostat if you live in a colder climate.

Heater doesn't work?


Your thermostat may not be working properly. Coolant flows thru your heater core where the blower motor blows that heat from the coolant thru your vents. If the coolant is not warm enough wich is a sign that your thermostat may be stuck open or opening too soo, your air may be colder than normal.

If ythe heater core is not bad then I would replace the thermostat, this will stop the warm coolant running up to your engine go to the heater core.

Heater does not blow hot air, just cool air


You can put a higher temp thermostat and that should help, but it should at least have 170 degree air right now if it was working right. There are two other things you might check for, the diverter door make some sound when you switch from heat to cool and back, I can't tell you for sure if it is a manual, vacumn or electric but that would definitely cause it to blow cold air. There is also a valve which cuts off circulation to the heater core when your not using it. This valve will be in line with the heater hoses going to your heater core. I have seen some that were actually part of the heater core box. I feel pretty sure one of these will be your problem. Also if your car is low on coolant it would not heat properly. Hope this can help you!
