You're in luck as I subscribed to the thread so I saw your question!

Here's what was on my invoice:

49154 found water entry from evaporator drains corrected evaporator drains removed front an rear carpets for drying retest okay defect 64 11 33 37 00 sib 64 14 07

I see one other code not sure if it applies 5147450 and FC 6411333700

My carpets have been dry for 3 years now so they clearly fixed the issue. Best of luck.
