Today I went to replace the rear wiper blade on my 08 Grand Caravan and broke the clip on the arm that holds the wiper, I cant seem to find anywhere that sells replacement arms, can anyone recommend somewhere to look. its the black plastic arm. Thanks for your time.

 

that's easy....the dealer. You might investigate why Dodge only used that flimsy plastic design for 08 and 09. Is the output shaft and window shape on later models the same??

Maybe a 2010 to 2013 setup is better and can be retrofitted?

 

x2 on checking with your dealer or if you want to save a little bit of $$ Google "Mopar parts" and do a search. I looked and this wiper arm costs around $30, so shipping costs might offset any savings from buying online.

I've long been contemplating retrofitting my 2008 rear arm with the 2010+ arm. I haven't taken a close look but it looks like the 2010+ arm has the universal hook-type blade attachment on it, as opposed to the 2008-09 arm that has the cheap plastic snap-type attachment that requires dealer-only blades. Can anyone with a 2010+ van confirm this? If this arm will only cost me $30-40 and it will attach to my 2008 rear wiper motor shaft just fine, I'm going to get it because I loathe the idea of paying $20 for a single wiper blade at the dealer when I buy the fronts at Costco for $8 each (on sale for $5.50 each through the end of March!).

 

I did some more searching and found that the 2008-2013 GC all have the same rear wiper motor, 5113411AB. I presume that the shaft that the wiper arm attaches to is part of that motor, since there is no specific component called "shaft". The 2008-2010 GC have the same rear arm, 68028437AA, and the 2011-2013 GC have rear arm 68102356AA. The shape of the glass couldn't have changed that much between 2008 and 2013, so the only other things I can think of that would prevent attaching a 2011+ wiper arm to a 2008-10 GC would be if there was something else on the glass in the travel path of the wiper blade/arm on the 2008-10 that isn't there on the 2011+, or if the motor/shaft's location changed significantly on the 2011+, both of which I highly doubt.

 

It doesn't help the OP with his busted arm, but the original blade is sold by Trico as part#16-E (Exact Fit) for about $10 or so. It is 100% identical to stock Chrysler part, so it appears Trico is the supplier for Chrysler. I know this because I installed one from rockauto on my van last week.

 

Hey, thanks! I think I'll be ordering one of those pretty soon. All the local parts stores show that as a dealer-only part. I just discovered RockAuto in the last couple of months, I didn't think to check there.

I'll keep the 2011+ arm retrofit option in mind in case I run into the OP's problem. I still fear busting that clip when I remove the old blade.
