IMO you should be checking out the common problems before opening up the battery pack.

 

thanks for ur help guys, but ...

today ive went to the mechanic and ...... we opened the battery pack, and we didnt find anything to check !!!

the fans are not working thats a definite, because we take off the fans cover, and reconnect the battery and switch on the car, the battery was hot and the AC was running and the back cooling system were very cold, but the fans are not running

then we took off the battery cover and then i told hem to not to go further, because all of the parts inside the battery are closed and i didnt wish to see them,

anyway,
guys, the fans are not hannged or dusted and i rotate them by my self, but they are dead !!!

we checked the relays and even i changed the fuses with new ones - its ridiculous but i did it - and nothing done

guys, is there any sensore or anything inside or outside the battery controlling the fans ???????

 

please people , answer me , im really confused

can u tell me ,the AC and the Fans working together when the temperature rise ?? or just using one system ???

 

The FEH has to be moving for the fans to spin up. If I sit in the back seat behind the driver in our FEH, I can hear the fan noise increase audibly above the road noise around 20 to 25MPH. I don't know if this happens when the battery pack is cool.

 

Saleem, I tried to help you in all my post but you either did not understand my English or decided not to take my recommendations. I did not in any way want you or anyone else not qualified to open a 330V HV battery and attempt a repair without understanding what you are doing.

There is a big possibility your '05 FEH did not have the recall battery harness replaced and TBCM reprogrammed by qualified Ford Techs by the Ford deadline. If this caused the battery fans to stop working a new or used HV battery would be necessary at the expense of the owner. This would be a good reason to sell a FEH to someone outside the US and Canada.

Vary few people know that warning codes can be reset and the PCM can be programmed to turn OFF systems that are causing warning codes. This could have been done to hide HV battery problems in order to sell a FEH. It is possible (I don't do it) to shut-OFF and turn back ON certain hybrid functions with a Scangauge II or ford dealer computer. This can be done to increase short term MPG or even hide system problems.

Now that you did not understand what I was telling you and you open the battery case, using the Scangauge II to located the area of your problem for repair is even harder.

The answer to your question above is if the AUX A/C is ON, the blend door should be closed to outside air (filter also) and the fans should be working.

GrayG, I mean GaryG!

 

i know what u were telling me, but im a kind of people that like to understand everything by my self after asking qualified people like u, i took ur recommendations in my consideration, and we were very carefull when we opened the battery,

ive checked the vehicle by computer and there was no error codes, and thats whats make me crazy, i dont know what to say, but

we didnt find any fuse, relay and thing inside the battery pack to change, and its sensors issue as i think and by that we didnt go any further,

so i dont know what to do>??? and i need ur help if i can check anything else that may control the fans !!!

and Mr.GaryG and sorry again for the mistake by ur name

 

Please select a corresponding number from the illustration below to view the details of that part.

16) Rear pipe

 

On my FEH fans running only when temperature in battery compartment rises, it depends of charging time, so temperature sensor should activate fans, I doubt that fans failed try trace from source like temp sensors and switches.
Did You ask Hybrid Engineer advice at Dealership?
