need help with 03 excursion 6.0

[SHARPCURTIS]

I just bought a 2003 excursion 6.0 really cheap, I know it has some problems and hope you guys can help me out..

1)my door light stays on all the time even though all doors are closed tight
2)my interior lights never shut off.just the overhead lights as if the door was open.I thought it would be the door thing but i always thought if the door was open for a certain amount of time it would just shut the lights off automatically which it doesn't.
3)When i start the truck up it fires right up but all the gauges have about a 15 to 20 second delay before any gauge works.
4)My windshield wipers don't work in front but the rear does
5)my ac doesn't work, and when i go to put it on vent nothing blows out of the vent.It shows on the display that the vent is on but i get nothing
6)my overhead counsel lights up with the lights on but cant see any display.

the truck is an eddie bauer 6.0 with 295,600 miles on it. the truck runs great and shifts great so mechanically its perfect..hope you guys can help, thanks

Most likely your door switches are gummed up. They are part of the latch mechanism. Spaying them out good with contact cleaner usually works. Be sure to hit every latch on the doors and rear hatch.
Gauge delay?
Wipers?
See threads about trip computers. They were poorly constructed and are known to fail, but can usually be repaired with a little re-soldering. Just be careful if you take it apart, often the resisters and chips have fallen completely off of the circuit board.
Good luck.

Oh yeah, your A/C problem sounds vacuum related. Do you have a 4 wheel drive? Vacuum leaks at the hubs will give you vent control problems. The auto locking hubs as well as the doors thet control air flow in the A/C system are vacuum operated. Also check your vacuum pump and hoses (on the passenger side fender well). I'm assuming your blower motor is working, just nothing blowing out of the registers.

x2 on the door switches/latches. I used a good penetrating lubricant to fix mine.
