I am crosslinking some posts here after reading up on this topic...
I read the TSB as linked here: http://chevyhhr.net/forums/showpost....8&postcount=12
And now I understand why my Service Writer is quoting ~10hr labor worst case scenario... the end of the TSB in Word Document form has a chart showing the sheet metal seams repair at estimated 9.4hrs labor, whereas the Butyl Patch and other seal repairs are est 1/2hr labor apiece.
Thanks for hosting the link for the TSB, 1Panel2NV!
I read the HowTo post from Tooter here: http://chevyhhr.net/forums/showthread.php?t=14263
Thanks for that excellent write-up, tooter1!
It's 12:07 (little over half hour since my last post), and my Service Writer says they have duplicated the leak finally by directing water in just the right spot over the top/windshield-side of the wiper cowl! So it is the cowl/patch area allowing water into the cabin and passenger side. He says $59 min labor to fix but would need to charge labor to get under the cowl and tear down panels to find the exact problem area. Makes sense to me. For now I may investigate the cowl and seal it the DIY HowTo way, or I'll run back to the dealership next week when money's less tight.
I appreciate all you've shared here and hope I can contribute some extra photos to those HowTo's if I do the digging this weekend. I was really glad to find CruzHHR
's OP from a year ago to get me pointed in the right direction concerning fellow ownership of original model year 2006 HHRs versus the interior water leakage issues. This forum is terrific! Thanks again!!
And thanks to the extra links on that HowTo, I can get hold of the replacement parts as needed, here
Usually, I can follow directions
Promising I won't post again until I have something meaningful
