2006 Lincoln Navigator, check engine on, battery light on, abs light on, and it won't come out of 4 wheel drive mode.

SOURCE: 1999 Lincoln Navigator ABS warning light turns on?

One of the ABS sensor's is bad or a hub bearing is bad.Could be front or rear.

2 different electrical circut's that are unrelated. Ac on a 12 year old truck is bound to need some service. Take it to a trusted shop that is not hurting for work & ask them if anything is disconnected, ie: compressor power wire, high pressure switch...ect. Tell tale sign system is low on freon is the compressor keeps cycling on & off with a clicking sound or compressor does not come on at all.

Testimonial: "Thanks that relieves my mind that they might have disconnected something accidently. "

Forget the four coils. That is a common problem,but I would question 4 failing.
The ABS ,Parking Brake,Speedo Etc,where nothing to worry about,you were loosing power, when it went to fail safe,so they came up.

ETC -is Electronic Throttle Control, your problem? Maybe
You will need to have a scanner put on it's,daignostic connector under the dash,to check for codes. Them only a trained technician can follow a chart or test proceedure to properly repair.
I have a 2004 LS,one of Ford most high tech and complicated vehicles.
Conclusion: only a professional can repair you car.
I would start with a local shop. If money you have money to throw away,go to a dealer.
Most likely have to wave to it on a flat bed carrier. Don't flat tow it.

SOURCE: abs and park brake light came on same time

Its either the speed sensor on the rear differential or your steering wheel is all the way down pinching a wire in the harness. I have had both problems. Raise the steering wheel and if that does not fix it then its the speed sensor(might be called something else) but it is on the rear diff.
