What is your question?
Fan runs on high as soon as truck starts and doesn’t stop. There are no overheating issues. Dealer says diagnostics check okay but this is not normal
How long has your 2013 Ford F-150 had this problem?
One week
Be aware the A/C compressor / cooling fan also engages when other HVAC selections are made other than air conditioning settings .. Turn ALL HVAC controls *OFF* and observe cooling fan operations while engine is *COLD*.. Good luck!
