This can be due to poor wiring to the motor or poor ground to the wiper motor causing this here.I have seen both cause low amperage and cause this issue.The motor may have its proper power and ground signals but they may be weak signals due to damaged or corroded wiring or even loose connections causing this.I would inspect the wiring and see if any issues are found with it and if checked and found to be o.k. let me know so we can continue.
