If that fuse is okay. try giving the wiper motor a jolt by whacking it end on with a broom handle. Can you hear the wiper motor running? Check the linkages.

The blower motor is behind the glove box, sit in the passenger side seat and kick behind the glove box a few times real hard with your heat on high, the motor might kick back on, I had a Buick and the same thing happened

likely your problem is the blower motor resister which is usually close to the fan.

The motor has to have voltage and a good ground.
Could be a faulty ground connection.

The fuse for the blower motor is in the floor concole fuse panel (see picture below). Also below is a diagram of the fuse layout. The fuse for the blower motor will be the fuse in the number 25 position. I hope this helps and good luck.

Look in your owners manual for fuse block location - it should also tell which fuse is for the blower motor. Check fuse - if the fuse is good then check for the blower relay location and test that relay. Most vehicles have a fuse AND a relay in the blower circuit, but not all - that's why I recommend looking in the manual. If you don't have the manual call the dealer after writing down the vin # - they can help you find what you need.
Good luck!

Change the blower resistor under the glove box. Takes thirty minutes.

REPLACE UNLOCK MOTOR.
