I can't make sense of the fault code, hmm...
Good luck/Bill
Hey Bill,

Thanks for the info, certainly will check it out.

Belt looks to be fine so far and the car is originally from LA (Im in WA) So I assume the AC was used a ton due to the large amount of humidity down there.

Someone told me about the acuator doors but not too sure about how the whole HVAC system works as a whole

I will investigate and if anything positive I will share. Cant imagine im the only one out there with similar issues with F25

Thanks,

Jake
