Question about Cars & Trucks
Can't tell what you are driving, but Ford made products use a Blower Resistor that can cause problems. Sometimes hitting the part with a broom handle will fix it for years but keep the broom handle in trunk for the next time.
Part is located by following wires on blower motor across Firewall to First or second device on that wire loom. The part has 1 electric plug in and 2 fasteners holding it in place. May be mounted in ductwork or metal Firewall. 90% of the part is hidden inside airflow cavity to work.
Entire part is about the size of a pack of cigarettes and usually made of black plastic. Very expensive for its size and no guarantee new one will not fail after Warranty period.
Now if you have a Digital dash, not just Temperature numbers, some have a self-diagnostic loop which will Diagnose problems. There are sequences to activate it and Code lists to explain the answers but the information is difficult to find outside the Dealership.
Please rate my info.

I'm assuming the problem is the blower motor isn't coming on or working. 1st, check the fuse. 2nd, remove the glove box or pull the 2 tabs that act like stops when it's open ( the glove box will open out further) and you'll see the power plug connector for the blower unit. Turn on the blower through the climate control (heat, A/C, or whatever) and wiggle the connector to see if the blower turns on. If starts working, then an easy solution is pull the connector off and gently press the prongs together or inward. Then carefully reconnect with damaging the prongs. This worked for 96 Mark VIII due to the fact the prongs were not "seating" correctly in the female connector. It's been about 2 years since I did this and the connection is still good. If wiggling the plug doesn't work, pull the plug, turn on the climate control (heat, A/C), and check for voltage to the plug. That's about all I can help with.

Either Your fan switch is burned out or you blower motor is no good, your blower motor is on the passenger side under the dash. Before you replace any parts you need to check your fuses and relays under your hood and in the car. Usually if your fan switch goes bad you will still get some air blowing thru the vents, so my guess would be blower motor, If its not a blown fuse or relay.
