2000 Expedition 4.6

I already owe you a good dinner.. I decided to not over complicate this, and just hook up 12 volts to the motor once I get to it.. I’ll work from there..From everything I’ve read, it’s probably the motor..

I suspect the motor, but manual not clear about fuse location..Shows only 601 30A
Master, and door switch shows no sign of life..

601 is definitely the fuse location.

First additive I ever used that worked
