If you mean you have to lift much harder than normal on the handle to get the latch to pop, older Chryslers used to develop the same problem with a real easy fix. Look on the back of the door for a curved slot. Inside that slot you'll find a bolt that needs an Allen wrench to loosen. I seem to recall that on Chryslers that was a 3/16" or 7/32" wrench. Loosen that bolt, work the outside handle a few times, release it, then tighten the bolt.
