Heater valveはrecallか？？

RE: AC Blows Hot Air on Sides, Cold in Center

--------------------------------------------------------------------------------

It worked! They replaced a defective pump valve. On the work order it says this:
Verified found TSB 201388314
CAUSE: CK Recall
799 NGO, DAT Lic#: 4806
WA
1 4F1-959-617-B Valve

I'm guessing that's a part number. Whatever it is, they fixed it, no cost. And it appears to be working properly, which is great since we've got some heat on the way!

Thanks again to Kevin for posting that TSB. I printed a copy from your post and took it with me to the dealer, who attached it to their paperwork. That got their attention!
