1994 f-150 5.0 L, 4x4. My speedo, odometer, went out and my auto transmission started******** hard when shifting into higher gear. I had the same problem 3 years ago and I changed a blown fuse (position 18) and it worked fine.
The same problem showed up 6 months ago, but this time the fuse was not blown. I took it to a mechanic who replaced (he said) the relay control module ( part #F6DF-12B577-AA). Does this sound right, and how do I find the location of the module on the truck and how easy is the repair myself if I get the part? Thank you
