I have a 2005 Nissan sentra and the heater wont stay warm unless i am accelerating. The AC is doing the same but in this case it does not stay cold unless i am accerating. I was thinking of changing out the thermostat to see if this would work, does anyone have a solution? the vehicle has no leaks and all fluid levels are good. Thanks, B

Find the big hose that comes out of the top of the radiator and follow it to the engine and that is where the thermostat is located. My advice is to be sure to get a factory thermostat and rubber gasket as it makes installation much easier. I have done it both ways and the factory one is easier to install.

Dexron-III is what's used in almost all vehicles (except some older fords and chryslers), but you can check the owners' manual to be sure (or call the nearest Nissan dealership).

I am having/had the same problem. My rear heater has not worked the last 2 winters, still trying to figure that one out. But I think I solved the front heat problem myself. The heater was blowing cold air while idling and hot air when the car was moving.

I jacked up the front of the vehicle, took the cap off of the reserve tank for the radiator, turned the car on and ran the heat (AC off) for 15 minutes. This is supposed to release any air bubbles in the coolant system and I did see air bubbles emerge as I was watching (this might be normal occurance, I'm far from a mechanical expert). Anyway, this did not immediately solve the problem, still blowing cold air as it sat there idling after 15 minutes. Dejected, I put the cap back on, lowered the vehicle and resigned myself to taking it to a dealer.

But a funny thing happened the next day, the coolant level was a lower (no leaks on the floor) so I filled up, and sure enough, when I started the car and let it warm up a little, hot air started coming out of the heater!!!

As far as my wife knows, I fixed the problem for the price of a bottle of coolant, so I am a hero...but at first I thought it didn't work. Here we are a month later and still blowing warm air and haven't had to replace any more coolant...the internet is a wonderful thing!

Hope this works for you, and I hope I can figure out my rear heater problem as well.

I had this question initially. However, the Nissan Sentra (starting in 2007) has an electric Power Steering. It DOES NOT need any power steering fluid. The electric power steering is suppose to give you better fuel efficiency and lower maintenance cost.

Open the trunk and locate the trim door that covers the back of the drivers side tail light assembly. Open the door and locate the bulb holder. The bulb holder can be removed from the tail light assembly housing by turning counter clockwise 1/4 turn. Holding the bulb holder in one hand, press gently on the bulb and turn then bulb counter clockwise to remove. Replace with a combo bulb and reverse proceedure to re-install.
