Camry Hybrid, 2007, Hybrid failure. Ive checked each batt

This answer was rated:

Camry Hybrid, 2007, Hybrid failure. Ive checked each batt cell and all read just above 7.5 VDC. The failure happened when the trunk was full of luggage, I suspect overheating. I just checked the airflow from the filter behind the seat to the fan. Seems to be some blockage.
JA: Have you checked the coolant? Have you checked for a leak in the cooling system?
Customer: Noticed there is a service buliten: TSB-0182-13 This is in the back, battery system. Not the radiTOR.
JA: Are you fixing your Camry Hybrid yourself? What have you tried so far?
Customer: Yes, a month ago i did have one bad cell and replaced it. Worked great for a month. But this time all cells look good.
JA: Anything else you want the mechanic to know before I connect you?
Customer: Yes how do I remove the filter?

Thanks Chad. Yes I did that on the freeway, in order to get it home. That and disconnected the regular 12 Car Battery.
Do you have a proceedure to test the cooling fan?
Do you know how to remove the filter above the fan, so I can clean it out?
Customer: replied 2 months ago.
Right now the hybrid battery system is on my workbench torn apart. But I strongly suspect this is a cooling issue.

yes i do ,let me send it to you

Customer: replied 2 months ago.
Please let me know when you have sent it.

check it the battery fan relay ,from the relays pins and you can sEe if power going to fan, now the fan will not activate unless reaches high temp or TURN AC ON THEN IT SHOULD STAY ON AT ALL TIMES WHEN AC IS ON , IS IT

OR TAKE ALL OFF, AND TEST IT STRAIGHT FROM CONNECTOR

Do you know which pins are the 12 VDC for the fan?

it looks to me that Pin #1 is power and pin #4 is ground based on the wiring circuit diagram

do you have power on #1
