I need help driving down the road and at random times my wipers cycle one time. Also when I press the switch to raise or lower the pass. side window from the drivers side only the wipers cycle one time.

Sounds like you have a collection of grounding and wiring issues. The ground on the wiper motor is probably the easiest place to start.

I have the wiper housing grounded to the battery and that didn’t help any

No I have checked all the wiring and nothing chewed on.

Wipers should have constant current from white wire (WHT-93) from fuse box. They work when one of the other wires complete the ground at the wiper switch. So a wire is grounding out somewhere. -also- The switch or wiper itself could be bad & occasionally grounding out.

PNK-94 ground -washer
PPL-92 ground -fast
GRAY-91 ground-slow
BLK/LT BLU-97 grounds GRAY-91 (slow) until park switch opens at end of cycle,

BLK-150 ground

I traced all the wires associated with the wipers and still the same problem. By chance I had another truck with intermittent wipers and changed out the module and everything is perfect now.
