Maybe its your blower resistor?

Did this reboot work?

I am having the exact same problem as above on my '08 GT. It starts working fine and then suddenly the air just quits blowing although there is no change in blower speed (based on what I can hear). I am looking at the reboot procedure, but am not sure how to disconnect the EMTC module electrical connectors. Do I have to pull apart my dash to get to them?

Thanks.

Back from the dead...

I've searched and am not finding an issue like I have. I came across this post but there was never a final resolution posted.

It appears the original post was regarding a 2008. I have a 2010 and the fan speeds varies on its own, like I'm turning the fan up & down. I looked at the 2005 online manual and see the reboot proceedure but looking at the 2011 manual I do not see the reboot proceedure as an option. Either I missed it or in 2011 Ford changed the system. Does anyone know if a 2010 uses the same controls as a 2011 or if there a reboot proceedure for the 2011? The 2010 seems to be a blend of Ford components...

I'm thinking the resistors are going bad and causing my issue but before I take things apart I wanted to know which trouble shooting proceedure to follow, 2005 or 2011.

Any help would be appreciated.

I couldn't make it happen at the shop (go figure), and then winter came, so I haven't been using the AC lately. I did message Mayberry and got this response:

The AC was recharged and that fixed the problem! The stang was WAY TOO new for that to happen! Oh .....The compressor and all lines needed to be replaced also!!!!!! Ford was contacted and I was told it was just outside of the warranty.......poor workmanship on Fords part I think!!! The cost was $ 1200

Sounds like his was a cooling issue and not a fan speed issue. $1200 ouch...

I'm pretty sure the 2010 is very close to the 2011 in terms of interior electronics
and materials. I don't have access to my 2010 manual right now, but looking at
the online 2011 manual, in particular Pinpoint Test R (page 68), it basically says that
if the fan speed control is working, but acting weird, replace it:

Of course, the service manual says to pull DTCs before doing anything else, but
only a Ford-specific code reader can pull climate control codes. If you have
access to one, couldn't hurt, but you're probably looking at a new fan speed control.

Oddly it seems to have stopped the erratic behavior... if it starts again I'll get a get a control switch.

Thanks
