Greeting. I'm a new member and have just purchased a really nice 2005 Excursion. The only thing that is not working is the little overhead electronic trip computer (Miles to empty; mileage, etc). The display is blank and I can't get it to turn on. Anybody have that issue? If so, what's the best way to approach fixing it? Thanks in advance.
The most frequent issue is the resistors on the circuit board de-solder themselves from the heat from the roof. Remove the over head console (1 screw in the glass compartment, then you pull down snugly on the rear, then it'll hang down so you can remove the wire connectors.
Then send it to CircuitBoardMedics and have them fix those resistors and anything else they find while inside it. Unless you are super handy with a soldering iron and tiny circuit board parts...
I had the same issue on my '05, took it apart only to find that 4 of the resistors were broke in half. I found a guy on eBay that repaired it for $20. I sent it to him on a Friday and got it back the following Thursday. I think it was automotive circuit solutions, or something like that. Just go on eBay and search, excursion overhead console.
Soldering it yourself is pretty darn easy. I just did this about a month ago. I waited so long because I was apprehensive about doing it but it was very easy. Give it a try and if you screw it up then you can send it to one of the places recommended.
I did this myself and turned the board over where the four resisters are heat the solder up and helps lock them in place, but make sure you use something to hold them in place.
I'll add in that when you take the board and look at it, there may be nothing obviously loose. Just take an electronic soldering iron with a fine tip(Radio Shack, Home Depot, Amazon) and touch the connectors for those chips (on the back side of the board) You can see the circuits easily from the back of the board. Don't get carried away with solder if you have to add some. Also use the very thin electronics solder. After all that, just take the module back to the X and plug in to see if it works before you put everything back in.
