I'm experiencing random fan speed and temperatures on my HVAC system. The truck is a 2006 F150 SuperCrew XLT Lariat w/5.4L Auto Climate Control System.
Does this sound like a sensor gone bad? Any idea where to start?

Thanks!

Subscribing... I have random fan speed sometimes. I would like to know the solution also.

Run the self test...

and see if anything (code) pops up.

Got a code 13 42 on mine. Trying to find out what that means exactly.
