the electrical cluster does not work and Ford says they can’t find one on my 2003 thunderbird
17 year old car, not many built, Good luck finding one.
You might also post this on any last-generation T Bird forums you can find.
I don’t know the details of your situation… but I’d get a second opinion or diagnosis. Entire electrical clusters don’t need to be replaced all that often.
If you took this 2003 to a Ford dealer (which it sounds like), they may have given you an overly expensive/difficult diagnosis to make you go away. Dealers generally don’t want to work on 17 year old cars, especially rare/discontinued ones.
Just my two cents.
Looks like the part’s been discontinued for some time, despite some online ford sites still selling them. https://www.thunderbirdspecialties.com/2002-2005-thunderbird-instrument-cluster-problems/
Could really be the Front Electronic Module causing the problem.
There are places that can repair the cluster. Do a web search.
