My wife drives an 08 FEH with about 62k on it right now.

Over the last few months it's been giving a wrench light that comes and goes and does not leave a diagnostic code, at least according to the tool available at Autozone. Internet research suggests this is a typical symptom of a faulty blend door in the battery cooling system.

Q1: Is this covered under Ford's hybrid drivetrain warranty? (I don't like paying dealer prices for work done on my coin)

Q2: I'm not afraid to work on this car where practical, and I own the full FSM. If this problem can be diagnosed or repaired by me, I'd appreciate any suggestions or starting points.

Thanks,

Dave

 

IF it is the blend door, then the instructions to repair this are here: http://www.escape-city.com/viewtopic.php?f=24&t=1229

 

When I had the intermittent light it was the HV Batt blend door/act arm. Luckily I was still under original warrenty, other posts point to it NOT being covered by the hybrid extd warrenty. Go figure, it's a part only found on a hybrid, and it protects one of the most expensive (maybe the most) Hybrid parts.

I looked at that link before, it seems pretty easy DIY, I think the part is like $20.

I think one hint it was the door is the light was more intermitently on when it got hot out.

 

Thanks everyone.

While it's technically bad form to change parts without a diagnosis, given how often these actuator doors seem to fail and that it's a DIY'able $19.33 part, I might actually start there.
