I can turn my heat on it works it clears up windshield but will not come any where less and seems to be stuck on low. I don't hear the fan come on at any time.
The part broken is probably the blower motor resistor. Go online and look up this part by Year and Model. Sometimes besides the part, a photo of the location will be included in the article.
This is a part that sometimes can be tapped with a broom handle or snowbrush and reactivated. Sad part of this is that it may work longer than any replacement part you would buy. Some had bad solder on components and would reconnect by tapping and arcing a new bond. So I really can't say that a new part would last better.

It's even odd that you were getting a step-type voltage when you first checked.
Many speed regulators are simple tapped resistors with the switch selecting which tap is connected to the motor.
More elegant controls would use a semiconductor (transistor) and a few other components to supply step-variable voltage to the motor.
To determine which is used on your car, you will at least need the electrical diagram for it, preferably an aftermarket service manual - Haynes or Chilton should be available at least in the US and Canada.
Those will contain not only the electrical info you now lack but possibly instructions that will aid in locating the controlling circuit.
I suspect that circuit is faulty; if the resistor type, it will be a device with mulitple taps, if solid state, a few parts on a small board.

check for ground going to fan. If there is no ground replace a/c control panel located under radio it what you use to turn on the heater/ a/c

I had the same problem with my 2000 Mercury Grand Marquis. I ended up replacing the blower and the resistor which is on the passenger center side of the firewall tucked in where it is hard to get to. Everything worked fine for about two years. It just went out again here about a month ago. I am going to try to replace the resistor again, but I am wondering if it doesnt have something to do with the climate control switch. I do not want to replace the same part every year or two, so if anyone has a idea of what could possibaly be the bigger problem, please let me know.

hey there cjwalker,,did you try the blower ressistor its located beside the heatermotor ,,it controlls the speed of the motor ..should be easy to remove ,,,either 2 screws or else it just clips in,,,,,
SOURCE: ac or heat wont blow
Needs a blower motor resistor if the fan only blows on one speed. It is located underneath the firewall on the outside, near where the passenger exhaust system is. You need to take the passenger side cat converter off to get to it.
