1999 Ford Expedition Q&A

1999 Ford Expedition Question: my 1999 makes a loud knocking noise when in park

my radio goes out when driving and my 4x4 sensor light inside dash flashes and when Im driving and come to a stop it makes a loud fanning noise in engine. also when I turn off engine in the inside dash it makes a clicking noise -
Answer 1
scan codes but sounds like you have a couple of issues. clicking noise could be air door actuators and fanning noise could be locked up fan clutch. just a good guess but start there -
