The problem is that heater fan motor. They are prone to failure when the brushes in the motor wear down. Replace it, they are about 100 USD

I have a 1999 buick Lasebra the heat or fan is not working what could it be

Well it could be any one of a few things ! There are two blower motor relays , two fuse's an the blower motor resistor, but wouldn't think that is the problem unless you have high speed blower operation ! But then again don't know if we are even talking about the same fan ? heater fan not cooling fan ?

My 1999 alero fan will not work.I have replaced the blower motor and checked fuses and still nothing.The heat and air are working fine just not blowing.

Its either a bad connection on the blower motor resistor or a faulty blower motor resistor.These are known for over heating.

1999 ford taurus fan blower not working if it is the fuse where on the inside is it located?

The first thing you want to do is take a test light and probe the wires right at the blower motor and make sure you are getting power there. If you are not getting power there then its possibly a relay or fuse but if you do get power at blower motor then replace motor and presto you have heat and air.

A/c and blower does not work i have 14 vots to the fan but still wont work

If it has power you need to confirm if it has a good ground. If it does it may be a defective motor. If not it may just need a blower resistor or have a wiring problem.

Sounds like the blower fan wheel has dismounted/broke from motor shaft. Actually quite common in the windstar. Pull the fan motor and replace.
