I'm around Phoenix AZ, it's hot. That's important for what's next in my symptoms:
1. Only when using (or just after using) my AC, the cooling (radiator) fan runs like a jet ready for takeoff.
2. this is MOSTLY when the engine is "cold", but also there- just less so- when warmed up.
3. only winds up when I hit the pedal, not at idle.
4. AC works fine, no engine overheating, no codes are thrown.
Was thinking...could be a sensor...could be an overcharged AC system...but really not 100%. I'm pretty good mechanically, but not great with AC systems or electrical. If a sensor...which one?
Anyone ever run into similar and find what was causing this? I've searched the web, but not a lot of info found yet.
Thanks all-

i’m thinking it has to do with the air conditioning condenser coil being hot/ high head pressure …have you tried cleaning the condenser coil with a hose? maybe it’s clogged with dirt ..when you accelerate it probably initially raises the head pressure and compounds the problem.
also wonder if you have it in tow haul mode if the fan runs higher
