Am I the only one
 

I have a 2003 Lincoln Navigator that is giving me nothing but trouble. The best way to explain it is everything that luxury about the truck is broke. The heated and cooled seats the memory for the seats the 4 wheel drive don't work. This list continues with back-up sensors don't function basically everything electrical is not working. Although the truck runs great aside from all of that. Any suggestions would greatly help me in figuring this out.

Fuses or harness????

Sounds familar. i just had to rewire my door lock motors so i can actually get in my truck. i just had a major air ride failure, its not fun at all

I wish just one thing was broken but instead it's all of the above.

Even though it's multiple things it could be caused by one harness or fuse. I just got rid of my 2003 Surburban which had multiple probs like your's and it was tied to one broken part. I'll keep my fingers crossed for you.

Start with the simple stuff like go to the fuse box and push all of the fuses back
into position. They tend to creap out through heat and cooling cycles. My wifes
03 Nav has had the running boards fail multiple times and other probs as well.

Good Luck

Thank you for all the help and I have tried the fuses and all the connections to the ECM with no luck.
