By fan I assume you mean the engine cooling fan. You need to verify that there is freon in the system. The ac system will not work at all with little or no freon as a failsafe to prevent the compressor from burning up.

The resistor bank is bad for slow speeds, the switch is bad for high speed. In your test, you have voltage, but the switch wont carry the amps, to run high speed. Open circuits will not blow fuses. Replace both switch and resistor bank for all speeds. Make sure to clean leaves and trash from fan housing and see if fan spins freely.
Let's start with the passenger compartment fuse box. If you checked the 30A HEATER fuse the blower motor should run at various speeds as you operate the blower switch. If you checked the 10A REAR WIPER fuse (!), and also checked the 30A ADD (?) fuse in the engine compartment fuse relay box, turning on the air conditioner should operate the A/C relay to turn on the condenser fan motor. If this doesn't solve your problem, you'll have to trace power through the various circuits.
If nothing is coming out, put your hand on the blower motor under the glovebox and put the fan on high. You should hear and feel it. If not you may have to replace the blower. Dont\'t replace it till you verify it is getting power.
Try a SHOCK test to the blower motor case. What I mean is SHOCK the case by hitting it with the palm of your hand (make sure you have the blower switch 'HIGH' and the IGN key also 'ON'.. if the blower starts working, you have an intermittent contact in the motor itself. If this doesn't work, get a test light and connect it to the connector that plugs into to the blower motor - if the test light illuminates, then the problem is obviously in the motor. If it doesn't, then you have a wiring/switch/power supply problem.
Well, the blower resistor handles the lower speeds and the hi-blower relay handles the hi speed only. if the fan still works on the lower speeds then the resistor is bad. if the fan doesn't work at all then your motor has failed and or burn't the relay out also. if you can get your blower to start by hitting the kick panel above the pass. side foot area then the motor is bad. if you are handy enough to drop the kick panel and access the motor then check the connections at the motor. Then wack the motor and see if it comes on then. you will most likely find the problem if you follow those simple rules above. Good luck.
