I Installed a new stereo on memorial day and now my Navigator wont move!

Thanx I wasn't sure if it was that or the ECU? Thanx again I'll check it out tmrw.

Put it in 4wd to see if it will move!

Hey Pushrod Thanx it was the Motor in the transfer case! It Seized up and wouldn't move to select a gear!! New motor and it works great!! Definetely glad it wasn't the whole Transfer case!! LOL Thanx again!

Glad to hear you got it fixed!... Thanks for the feedback!!

Thanx for the quick reply! This is my kid brothers trk and I've asked him several times if maybe he had touched anything to metal?? He said that he didn't have to do any wiring in the dash cause he had a harness for it. However he did have to change some wiring for the rear speakers!? Thats why I checked all the fuses and relays today because I thought he might have shorted something out, seeing as how he didn't disconnect the battery while doing this! (First mistake!) Another person responded that it could be the Transfer case? So I guess I'll be busy tmrw! LOL Thanx so much for answering so quickly!

Coolant sensor, exhaust temp sensor. Sounds like some kind of wiring or circuit issue. Good luck

Thanx I was thinking the same thing. That or he screwed up the ECU and its sending bad info?! Thanx again have a good nite.
