- The duct fan is bad. Replace it. Beware though: it's a pain the butt.
- After you replace the blower motor and it still doesn't work, take it to a shop for testing if you can't do it. Other possiblities are a switch, relay, resistor, fuse, wiring. You can eliminate the fuse by swapping it with another of the same. You can try the "tap test" by rapping on the dash sometimes over the glove or on the blower motor itself, somteimes a weak motor may temporarily start working. Oh yeah, all blower motors aren't bad to change.
- If it's blowing air, but only COLD air, check that your engine coolant isn't very low.
- Sounds electrical, check the blower motor relay, although it may be switch or motor.
- This happened in my car! After replacing the blower motor (it wasn't broken afterall), found that it wasn't getting power due to a faulty ground. This was right behind the a/c heater radio console.
- With the fan only blowing at the 4 setting indicates the resistor need to be replaced. The resistor controls the flow of electricity to the motor, w/ the 4 setting not limiting the current at all, which is why you the fan works at that speed. I'm in the middle of trying to fix my blower too, but so far no luck. I've replaced the motor, but nothing's changed. The volt tester shows power to and from the motor, but no movement. I'm not sure what else I can check at this point.
- Is the fan actually running or not? Can you hear it...but no air seams to be moving? If yes, then one of the duct-work doors may be stuck. (There are little electric or sometimes vacuum operated door inside your duct work) A wire or tiny hose to one of these may be loose or fallen off. If you cannot hear the fan running at all, even on it's highest setting...then consider looking at fuses, loose electical connectors (sometimes they get kicked off by a passenger). It's actually rare to have a fan motor die...although it can happen.
- This is a really easy fix, it's likely that your thermostat is stuck. This has happened to me on numerous occasions when I had rusty water in my radiator. The thermostat was stuck, so I replaced it and tada! You've got heat. Usually less than 10 bucks to fix.
what is the make and model and can you hear the blower motor running

How do you fix a heater that wont blow air in a 94 Nissan Sentra?
first of all i hate to say an obvious answer but does the heater motor even turn. Does it blow air at all. The first thing i would check is if the fan motor is blowing any air at all. If not u need to put in a new heater fan motor. first of all i hate to say an obvious answer but does the heater motor even turn. Does it blow air at all.

Any heater that only blows luke warm air isn't getting warm or hot water to the coil. This sounds like a problem with the thermostat not closing, and allowing the engine to heat the water properly for the heater.
