Ok with the engine at operating temp feel both of the heater hoses. both should be hot, if one is hot and the other is not . then you have a clogged heater core. flush it out and you will have good heat.
also check the wireing system for the cooling fan for any obvious wires that have been added or repaired. if all ok check the relay located in the fuse box under the drivers side dash and fuse # 13 & #15... the fuse pannel on the drivers side strut tower ( under the hood ) also has a sub-fan water temp relay

2003 ford taurus blows lukewarm when the heat is on. Blower blows fine and a/c works great.

Check out the heater hoses for warmth. Both should be the same with the water flowing. If they are not, the water is not circulating.

There are 2 ways the heater can work. One style varies the amount of water flow to control the heat levels. The other uses the blend flaps in the ducts to push air flow around the heater core.

If the heater hoses are not circulating water, a part called a flow valve is to blame. Check out the autoparts sites for photos of the flow valve for your car. If you have the blend flap system, a solenoid called a "motor" is not changing the position of the blend flap in the dashes' ductwork.

I have a 2000 pontiac grand prix with a 3800 v6 in it! For some reason the temp barely peaks over 180! The blower motor seems to kick out lukewarm air. the switch doesn't work on 1,2,3,4! It does work on...

You have two separate issues
lukewarm air causes:
not enough coolant
restricted heater core
stuck open thermostat

fan speed works only on 5
blower motor resistor is bad

Hope this helps, it it does please leave feedback Thank You and Good Luck

Heater fan sounds like a helicopter

you need a new or good used blower motor, they are located in the passenger side footwell, very easy to fix, just a few screws and an electrical connection. the blower motor is powered by "brushes" which wear out after a while and cannot produce the surge needed to start the blower. the bearings are probably also worn out which is why it is so loud. the reason it works as you drive faster is because in the fresh air position allows air to travel through the ductwork simply from the forward motion. if you put it on recirculate, you will notice this no longer occurs. the actual switches for the fan also like to burn up in these cars, if that was your case, you probably would have slowly lost the lower positions and then eventually all of them. something else to keep in mind.

Audi a6 heaters not given out hot air

this is more than likely a problem with your thermostat in the cooling system .heres a few things to check to be sure make certain your blower fan is on high and temp setting is in the hottest setting check to see if   air is coming from your heater ducts  also be sure to thoroughly let the engine warm up 10 to 20 minutes  before checking. if the air is blowing but  luke warm still your thermostat is stuck in the open position  and will cause the engine to run to cold and performance will also suffer as will your heat will not be sufficient  to heat the passenger compartment  this repair should cost no more than $150 max to replace buy a repair shop    this is a  common problem in older cars and this is generally   a quick  repair to be made  for almost any repair facility  should take under 45 minutes to complete once repair is started

Heater blowing cold air.

Check the water contol valve operation ( under hood connected to heater hoses), do you have a full load of coolant?, also air mix door under dash, is the temp of the coolant hot?.Check them all out, you'll find it

I would suggest replacing the blower motor resistor. When this component fails the blower will only work on one spped or none. This is a very common issue with all automotive models
