I think its Electrical? Can you help?
I have an issue with my 03 F-250 5.4Liter. I think it might be electrical. The truck will not go into reverse it makes a grinding sound like the parking dog is not totally disengaging, it will go into drive but sometimes when you let off the gas it makes the same rubbing/grinding sound but not as severe. Also the 4x4 will not work it will not even attempt to go into 4x4 high or low no lights come on or anything. Also when you turn the key into the acc power position the ABS kicks on for a second. This all started after i washed and degreased under the hood of my truck. is there a connection in the wiring harness under the hood that may have a common connection to the 4x4, ABS,or transmission if so what connection is it. i am going to pull all the plugs apart and inspect for water or other damage? The truck is in excellent shape and only has 55,000 miles on it.The tranny fluid is good and the linkage looks ok. again this happened suddenly after washing under the hood of the truck, with no prior warning or issues. any suggestions or advice??

As I spoke to you on the phone today, I'll just put this in here to bump it back to the top and see if anyone else has anything to say about this.
Let us hear from you and let us know what you find. I bet you got something wet and it blew one of the underhood fuses or relays.

I think the fuses is the first place I would start. May have gotten one of them wet.
Have you driven the truck any? One time I had a truck that I got wet playing in the creek. Everything was a mess but by the time I got home it was all ok from the motor drying it all out.

So all will know, he had two relays full of water under the hood.......replaced and everything checked ok....
Be careful on spaying water under the hood. He only used a regular garden hose...no pressure equipment.

Relays
What must have happened was when the cap was installed in my truck they ran a wire behind that relay box and they clipped it back on upside down so all the water collected in the relay casing instead of just running off. im glad i found out the way i did instead of being camping up in the mountains and had it happened there.
