Check if you have a blower resistor. Wires that come off the blower motor goes into the blower box. Chances are the blower resistor is bad.

Looking through manual and I'm not seeing anything for blower resistor.
It's under the right side under the dash, remove the plastic cover under the glove box, remove the blower motor, follow the blower wiring to the resistor there are 2 7/32 screws holding it in. I shortened an old 7/32 socket to make it easier to get on the screws because it's kind of a tight fit between the carpet and the resistor. This is a very common problem, the resistor may be called a blower module in your manual. I hope this helps, Take care.
Note the diagram for blower motor, according to my database, See the two wire connector for blower motor, red wire is voltage, fuse protected and hot all the time. Black wire is ground. You can use a test light to check voltage. If your worried about the ground, you can use redundant ground to see if blower motor will run. If good voltage and ground with no blower action, suspect the blower motor is faulty.
