95 Grand Cherokee - wiper works in low, high and washer modes but stopped in delay mode(s).Any ideas? Thanks?

If the interval (delay) function is inoperative, check the continuity of all the wiring between the switch and the wiper control module, located at the wiper motor. If the wiring is OK, check the resistance of the delay control knob of the multi-function switch. If these results are satisfactory, REPLACE the wiper control module.
