There may a problem with the blower motor resistor/connector. On the passenger side,under the dash, is where the blower resistor is located. I am going to send you information on this inspection and repair. If you have the blower on and wiggle the wiring and if it turns on then the connector and resistor needs to be replaced.
Why is my blower fan not blowing air?
The blower fan resistor is a simple electronic circuit that changes the resistance of the current sent to the blower motor, and enables multiple fan speeds. If you find the blower fan works, but only at a single speed setting, the blower motor resistor has probably gone bad.
How to fix a heater fan that does not work?
Cut the wires back far enough from the connector to eliminate any melted insulation on the wire. Use the old connector as a map for splicing the wires for the new connector. Be sure to use the correct crimping tool from the terminal repair kit J 38125. Use only Duraseal splice sleeves.

Why is the blower motor relay not working?
As I understand things – the blower motor relay acts as a switch completing the electrical circuit between the battery, your fan switch, the resistor and the blower motor. It operates when both the ignition switch and fan switch are in the on position. When this relay goes toes up – then nothing on the circuit gets power.
