2005 F-150 Electrical? Won't shift out of park
 

Hopefully someone can point me in a direction because after pouring over these forums and dismantling my steering column, I'm stuck.

Yesterday I got in my truck and it wouldn't shift out of park. A few quick searches and I was able to locate the button to manually engage the brake shift activator and drive home, however I had no turn signals, but my brake lights were functioning. When I had time to actually look into the problem yesterday, it had resolved itself, everything worked fine again.

This morning, same issues. After research, checking fuses and lights, I assumed my actuator was faulty so I removed it. With direct power it works fine.

Only other clue I have is with power on, my turn signal indicators are both lit solid as is my high beam indicator. Neither lights are actually on and turns signals don't function. If I switch on my headlights, high beam indicator goes off and then indicator comes on if I click on high beams. Without power hazard lights function properly.

I would consider changing the brake light switch, but when I disconnect it, the turn signals and high beam light stay lit, so I'm thinking an electrical "hiccup" somewhere?

Ideas??????????????????????


Thanks

One other symptom, steering wheel does not lock with ignition off.

Possibly it's The Multi Function Switch (Turn Signal Switch)

shifter linkage cable? from shifter to tranny?

Hey bud, I have this EXACT same issue as of today. Were you able to figure out the fix?

Try your PCM plug, see if it's loose... check battery grounds?

That's a common cause and would be the first place I start. The clip holding the shift cable to the bracket on the transmission is known to fail and fall off.

His symptoms were of a defective ground circuit but he never returned to report what happened.


if your symptoms are EXACTLY the same, check the grounding studs behind the passenger and driver's kick panels. If they are not EXACTLY the same, then clarify the symptoms.


Neither are possibilities, either would manifest in different symptoms.

If that were to happen, the shift lock override function would also fail.

Same issues here, I think I found the problem. 😶

Ouch. Extra ventilation, there, it seems.

Just need to fill it with expanding foam, and drill a new hole. 😎:coffee:

Had the same issue, that at times I was able to temporarily fix by manipulating the brake module (didn't know about the override). End of the day had to have the shifter assembly replaced under warranty.

same problem
 

Wont shift out of park
