Hi,
Certainly, the motor could be failing. However, we may not be getting a good power supply to the fuse or after. The wiper motor can only be replaced in conjunction with the wiper console, so let's make sure it is getting the power it needs.
If you look at pic 1 below, I need you to check the red/green and the red/yellow wires for power. Additionally, I need you to check the brown wire for continuity to ground. Do this with the connector off the motor. Also, when testing, wiggle the wiring to see if there are changes in voltage. Specifically wiggle the ground wire to make sure we don't lose continuity and there are no changes in the wire's resistance.
If these test good, chances are it is the motor. The remaining pics are the directions for replacement.
Let me know if this helps or if you have questions.
Take care,
Joe
