Question
I have a 2000 lincoln navagator and the air blows out of my vents extremely slow I turn the button all t the way up and nothing  can you please help me thank you

Answer
If I understand you correctly the fan doesn't work until you turn it on to maximum ?
The fan speeds are controlled by a resistor. This limits the voltage and therefore the speed of the fan until you turn in on to maximum
On maximum fan the fan bypasses the resistor and goes straight to 12 volts.

If my explanation of your question is correct then you need a new resistor/ rheostat
These are located close to the fan housing, you will see 2 or 3 wires coming out of a multiplug on most vehicles

If you have no fan at all, check the fuses and relays. If these are intact then find the wire that leads to the fan under the dashboard.
Separate the wire and give it 12 volts from the battery with a lead or power-probe.
If it doesn't run then the problem is the fan motor, if it does then there is a problem with the feed to it.

We are a UK company with no experience of your particular vehicle and will be unable to help further.
A good auto electrician may do better, or if you have climate control then a diagnostic with the dealer may save you lots of dollars in wasted time

Hope this helps

Expertise

Any question related to the function or malfunction of vehicle air conditioning excluding model specific problems with the heater controls. We are a UK based company and are unlikely to be familiar with the exact make and model of American vehicles. We will always at least try to guide the owner towards what the problem is likely to be in this instance We may struggle with none specific electrical issues related to the a/c without seeing it but it is likely we could narrow the problem down

Experience

Director www.chillywillys.org specialising predominantly in UK vehicles, fleet, rare and collectables. Although all a/c works on the same principal US vehicles have different controls and electrics. 12 years experience automotive and aircraft air conditioning. This is our sole source of revenue, we see lots of a/c issues that we are able to diagnose accurately mainly down to experience. UK have garages caught on to a potential revenue stream within the last few years but sometimes struggle with the problems as they don't see the issues that often........to be fair they could get their own back and ask me to change a timing belt ! Certain vehicles have known issues, we can help with that and also anything that is obvious to us but not necessarily to the bamboozled owner....... a/c is relatively new here and owners are catching on to maintenance but are sometimes still misguided by inexperienced individuals a bit timid to say' I don't really know
