Smoke smells when ac on nissan sentra


The speed control of your fan has resisters that are in the venting system to blow air on them to keep them cool. If they overheat and or burn you will lose your low and medium speeds of the fan. If you run the fan at full see if the smell goes away. Your engine could be burning oil on the outside of the engine block, make sure that the weatherstrip where your hood meets the fresh air intake grill is sealing tight.

Radiator hose blew,replaced it,now engine keeps overheating. Start it up... she runs normal,mile down the road the temperture gage rises to the H car stops running


first make sure there is not any air in the cooling system by running with radiator cap off and keeping coolant level full, but it sounds as if you have a blown head gasket. sure signs are consistant over heating, loss of coolant with no evidence of leak, or smoke out of tail pipe with a bitter sweet smell to it.

Bad smell from a/c


Do you leave your climate control in the Auto position. This is bad. What happens is the evaporator which is located in the vents never dries out and you begin to grow mold. Does it smell musty, locker room type smell.
Also since it came out the heat vent it could also be a leaking heater core. Check you coolant level and reservior. If low this is an indication heater core is leaking. It may not of leaked enough to tell but usually these are the only reason the vents would smell unless a rodent ended up there and died.

your fan motor is shot, motor has bad brushes replace it, if u feel its still not hot, drain your rad and but a 28 oz bottle of pine sole and add water till full, run it for about 20 mins. drain, run strait water, drain, then put anti frezz in with water, 50/50 mix or mix your own. it should clean your cooling system compleatly out.. do not turn heat on while pine sole is running throw it, gives of a bad smell.

1994 GMC Sonoma Heater Problem


Sounds like either your motor or blower resistor is going bad.Gm blower motors tend to go bad from what i have seen.My chevy pickup is on its 3rd motor.There is also a hose that is connected to it that when the air blows it directs some to the motor to keep it cool.You can check that but it is probably your motor

95 nissan quest - strong smell of exhaust in the cabin area


The exhaust leak is almost always broken studs on the exhaust manifolds. It makes a tick noise when cold and usually goes away when the engine warms up. After a year or so, the noise doesn't go away.

Your heater-a/c air intake is at the base of the windshield through the screen on the passenger side. WHen the exhaust leaks from the manifold, the exhaust gas gets sucked into the air intake.
You can put the heater in recirc mode and it will draw air in from inside the car instead of though the outside air intake. You can't leave it in recirc for long in winter or your car will get ice or fogging on the windows from too much humidity. Take it off recirc after 10 minutes.

Heater blows cold air


Assuming the temp in the car is fine..Sounds like a plugged or faulty heater core. Have the system flushed or remove hoses from firewall when cool and blow it out w/ compressed air
