I need instuctions to replace the rear wiper blade on a 2003 Jeep Grand Cherokee.

Take it to any parts store and they will do it for you for free, there are three types, the rocker type which you have to raise the wiper arm away from the glass then pull the tab up then slide the wiper down and slide the wiper off the wiper arm. but the best thing is have someone show you how to do it for the first time sometimes they can be tough to get off.

I own a 2000 and 20001 Grand Cherokee and resolved the rear wiper issue only by replacing the wiper arm. Grime and gunk and salt all contributed to a weakened spring and too tight a hinge.All my efforts to lube arm hinge and tighten/adjust the spring produced unsatisfactory results.Replacement will return your rear wiper blade performance to "as new".I hope to save you wasted time and effort and $$$.
