01 navigator clicking behind dash

Asked by Oct 20, 2019 at 11:25 PM about the 2001 Lincoln Navigator 4WD

Question type: Maintenance & Repair

I've a clicking behind the dash that occurring with or
without the ac unit on it seems to be affecting the lights at
night I just bought this truck and am not familiar with it yet
could it be the blend actuator and how can I verify that also
any one know the best way to get into it?

If it's blend door actuators, they wouldn't carry enough juice to affect the lights. What you're hearing might be the Body Control Module. They sometimes do click. Might also not be behind the dash, but actually under the hood; a defective alternator, and that can cause lights to flash or to not come on.
