Chrysler Repair: Intermittent wipers,2001 Grand Cherokee, intermittent wipers, internal surfaces

Question
The time between wiper cycles is intermittent. It does not matter the speed selected.They might cycle every 3 seconds then 10 seconds then every one second.If If I select continuos high, they might work continuously or they might cycle??

Answer
Hi Bill,
Sorry to say I don't have a wiring diagram for Jeeps. You might want to clean the internal surfaces of the wiper switch using electrical contact cleaner in a spray container.

I just saw your question in the 'pool' to which it had been referred after 'shopteacher' dropped out of the service, apparently.
