2004 Ford Excurison XLT 4X4 V-10 Gas 6.8 L 102000 miles. We bought this SUV to replace our 1998 Suburban ( 346000) miles on it.
We get home and a neighbor says, you have "no tail lights, or parking/marker lights, but the headlights worked, along with the mirror marker/turn signals. Ford dealer checked, said the headlight switch was bad. I replaced the switch and still no "parking lights!"
I found the diagram and run s new wire from Switch to L fender under the hood. I hooke this wire to a 30 amp circuit breaker. Then I run a new wire to both front parking lamp/side markers. I then run a new wire to the rear Tail/parking lights. This resolved the "No Lights Problem.
A week ago we were driving and my dash gauges quit working. Then I saw the 'red battery lite was on. Confident the Battery was good, I bought and installed a New Alternator (Rebuilt). Had a good Samaritan waiting to see if it would start, it started up and no problems. The truck was driven more then 120 miles and as I was making a Left Turn, all the dash went out, gauges, speedo and tach, radio stopped, windows would not work. No problem driving, and the a/c was still working. We had gone about 35 miles and made a Left turn, everthing was again working. Went home and checked the belt, alternator, Battery and connections. All were good.
Next day got in the truck, started and "all" was fine, drove for about six miles and "All" gauges and such come on, then went out. Truck was running fine, a/c fan was blowing, so I drove to autozone and had Batt, and Alt checked, both were good. I get into the truch and pull out of the parking lot, as speed increased all gauges went out again, now as I stopped they come on radio and such worked.
It appears to take a few minutes/5-6 miles driving and it does it again, take off from a stop and as you get up speed truck runs, but gauges flash and all go out. You stop and they come back on. I start, they go out on forward movement, come back on as you stop?
Hope this drives you as "Nuts" as it has me.
have the same problem?
