Intermittent wiper?

[tagjeep]

The wipers on my 93 protege have 3 positions,delay,low,and high.
On delay,they will sometimes wipe every 3 seconds,sometimes 5,and sometimes 15.
Is there a set time they're supposed to wipe.or can you "program" them?

I think they are supposed to be consistent and unsettable. Maybe check your relay and wiring.
