How do you remove the rear wiper arm on the 07 T&C? I feel that after I remove the nut under the cover, I am going to break the rear window pulling on the arm. Is there a clip or something holding it in place?

 

they come off the same as the front wipers. the arm is pressed onto the shaft. there is actually a special puller for removal. I have a trick I use but I'm not going to disclose it because it's crude and can cause damage if you're not careful.
