i just went thru this problem. the arn that the handle pulls is a rectangle plastic assembly. inside that assemply is the "arm" that gets pulled by the handles assembly. the plastic rectangle that is attached to the ahndle on the inside. cracked. causing the arm to not move the same distance the handle was pulled. makning me have to tug and yank. after replacing the part from my local junkyard. they charged me 5 bucks. the handle never worked better.
