Can't receive computer codes for windstar

Engine light came on in my 2000 ford windstar. Took van to autozone for code reading and employee stated I had no power at the termial. Could this be a bown fuse and if it is, where is it located.

Dont know if your Windstar is one of them, but on many Fords the OBD test port & the cigarette lighter are powered from the same fuse.

Is the cig lighter working?

Is it any wonder that I don’t smoke?
