The drivers door exterior handle sticks badly when the window is up. Works fine with the window down. The lever most of the time does not engage to window interlock & the handle needs to be jerked vary hard. Always work fine from the inside handle. Please advise.

 

I advise you put it in rice

 

Nah but seriously, go to Amazon and get a new door handle just to test. If the new handle works fine, then the old one is in the process of failing. The Zs exterior handles are known to eventually fail and need replacing.

 

i would pull off the door panel so you can see the rods for the handles, see if something is out of place when the window is up
