My '04 has had some wacky electrical probs since early June. My dealer tracked it to the "Smart module" which replaced the old Gem module of former years. They have ordered the part but I'm still waiting. There is a national backorder and are expected sometime this month.
My problem includes NO wipers or washers, NO interior light, NO keyless entry or doorlocks.
Be prepared for a costly repair....they are quoting me over $500 and the part itself is $222. But........if they do the repair there is a 12 month warranty. Otherwise there is no warranty if you buy it and replace it yourself.
They said they could get one from a yard but then it's just a 30 day warranty.
Kind of between a rock and a hard place.
Oh, and the other bad news is it seems this part is particular to the '04 FX4 with keyless entry. So, after 10 years, they no longer have to even have this part available.
I plan to get it fixed and look at selling this Ranger and replacing it with something else.
I contacted Ford about this and they have a CS agent keeping me informed but it is pretty depressing.
