Hi there I have a 2003 Chrysler 300m 3.5 base and I need to install a pcv valve in it, but with limited space between the engine and the cowl I'm have a problem removing the wiper arms to get the cowl off does anyone have any pics on how those wiper arms come off. Thanks
At the end of the wiper arm where it pivots, there is a black plastic cap that you have to pop off (I usually get under it with a knife blade and lift it up), then there is a 15mm nut underneath the cap that has to be removed. After that, just lift it right up. It's also possible to replace the pcv valve without removing the cowl, it just takes a bit of time because you would be limited as to how far you can move the wrench each time.
Mine must have been broken then.
For me, after I took the nut off. I applied pressure towards the windshield at the pivot point, and it lifted right off.
The tension of the spring in the wiper arm puts sideways force making the arm catch the threads on the stud
