Hey guys I own a 2005 Lincoln Navigator, the Park Assist light keeps coming up on the message display and there is no nose at all coming from my park assist when put in reverse and also my reverse lights do not work, I checked the no 10 fuse and it seems to be fine, any other ideas of what it could be? thanks

Bert

Have someone watch for the reverse ights as you move the shift lever through the gears. Maybe the transmission range selector is giong out.

Thanks Bert, where is the transmission range selector located?

Bert

It's on the transmission at the lever. Did they come on moving the lever?

No unfortunately they did not, my "check park assist" light stays on at all times

Bert

Then it could be anywhere in the system. You need a manual to track it down.
Was there power at the fuse? Are fuses #14 and #27 okay and have power to the in the run position?

Fuses look fine, I think I'm just going to take the it to the dealership and have them diagnose it for me then repair myself if possible, thanks for the help bert

Bert

Sorry we couldn't get it. Post back what you find out.

So I took the truck into the dealership and the tech there had advised me that wires from the MLP sensor to relay were corroded or shorted and that this is a common problem. That problem then stops the parking aid and backup lights from working (they share the same circuit). So now they are going to track down the corroded/shorted wire and replace it. Wow this is a headache, and hurts my pocket at $135.00 an hour. I hope it helps someone who is dealing with the same problem.

Cheers

Bert

Thanks for the update. Soetimes that's the only way to get something fixed and not have the headaches with searching for weeks.
