RE: ECU freestar 06 4.2l
You could try the junkyard websites to order one. However, I am courious, are you out of warranty at this time? There is a TSB from Fordfor the 06 for water intruding the ECU area in the fire wall. This should be taken care of by Ford?? ANd if they tell you it is due to Washer fuild, how by color? Then it was defective from the factory............
