Park indicator light stays on

Need help,

 

So when you shift the column shifter, the light for park is the only one lit?

 

No, even when the truck is off and key removed the light stays on

 

There are a few things we've seen come thru here with this problem....

By chance is your clock or any other items staying on ?

Trailer Harness
Tail Light Relay, behind driver side fuse panel
and in some cases with water penetration on drivers side, the Integration Relay itself has corrosion

 

Yes, the radio stays on as well

 

I'm suspecting this may be another case of windshield or a-pillar leaking into the interior fusebox, which we've seen plenty of times... (pics and more pics).

 

Yeah seems like it's staying in "accessory" mode. Could also be a keyswitch issue but water intrusion definitely shouldn't be ruled out.

 

Thanks everyone, I’ll be back on it tomorrow. I’ve checked every fuse inside and under the hood, every fuse test good. The only way I’ve been able to make it go off is to pull either the DC “short” fuse or radio fuse

 

Well, if you looked at the pics I linked, it's what's inside the box you probably need to be worried about.

But that said, did you inspect carefully under the hood and inside the driver's side kick panel for any splicing someone has done? T-taps, other bullshit like that? Any signs of an aftermarket alarm?

This stinks of the kind of stuff you see in one of those two cases: Water got inside the cabin fusebox, or an alarm or other aftermarket component is shorting because someone used scotch-lok style taps.
