intermittent wiper function quit (loaded 98)

Is it probably the whole lever/switch or just the nob that twists at the end. All I have now is wipers on kinda fast when at Int, then slow and fast.

what year Jeep are ya playin' with? If it's the earlier ones, I'd say probably the control module. Located under the knee panel to the left of the steering column. Held up there wilh "velcro" style tape.

oops- just saw the "98" in the title-- don't know if '98 uses that silly module..... never mind
