Who here has done the latest SYNC update yet? Have you ever experienced crappie A/C like a lot of us have? Have you noticed that the A/C is performing better now?

Im not sure if there even connected or if the ambient temps and humidity helped but today(first time driving the truck since the update) the A/C had 38-39* vent temps. I do have a resistor installed but its never gotten down that low before, with or without the resistor.

I have sync 4.4, works fine. AC, still sucks in the hot weather like it always has...

 

I don't mean to burst your bubble, but it's probably the weather since we're no longer in the upper 90s. I noticed last week that my F-150's A/C was actually kind of cold, not freezing like my Z-71, but functional. I haven't done any kind of SYNC update.

 

What would sync have to do with the ac system anyway? That would be more like a ecm reflash

 

The MFT screen controls the A/C. It was just a thought.

Resistor?
