hi folks,
my 2011 XLT had an electric problem. Gear shift stucks in park position - bad fuse(breake light) has been replaced in that case - and it worked. So far so good - but this happened several times in the last 7 days and we run out of spare fuses.
My Ford dealer has replaced the electric connections within the trailer coupling after 5 days searching and billed over 500$. But yesterday it happened again. What i must say is, that the Expedition is very rare in germany and even Ford didn't sell it here(i imported this fancy car by myself). But has any one a suggestion, what i can tell the dealer/service team to find the cause?

It will be helpfull to get the wiring diagram for the shift lock solenoid or the brake switch.
regards from Germany...

 

Check the brake light switch. When it goes, it disables the shifter function as well

 

I agree.
Also the service shop should be able to hook up their scan tool and be able to see if the brake pedal switch is closed or open depending on pedal position. If the pedal switch reads closed on the scan tool and you still can't get out of park, you may have a wiring issue between the brake pedal switch and your shift inter-lock, or the actual solenoid is on it's way out.
