That's a tough one. I'm guessing this is a vehicle not sold by Ford in Venezuela? In the U.S., they've warrantied the MFT for 5 years.
In the U.S., electrical parts are typically not returnable once opened. It could get expensive trying to swap parts to find the cause, and it may require a dealership's computer to set up the new unit after installation.
It was bought on Ford but here the laws are not like in other countries, basically you are lucky to buy a new car and as soon as you leave with the car you have 0 warranty on it.
Will try to install it myself and if something occurs will go to my ford tech guy. If you take your car to the ford dealership it will take around a week for they just to start working on it and they dont have any spares.. just one of the small issues here
