I think I have a bad park - neutral safety switch. Anybody know where it is located on a 96 Jeep Grand Cherokee?

a/t (automatic)
is the PRNDL switch on the side of the trans. the N part, does that.

ok steve.
what transmisison. ? r?
on the A/T there is on the side of all these, a shifter rod.
and on that end of rod is the PRNDL, "prindle" switch.
this switch tells the TCM what gear your in
and to glow the reverse lights.
and to prevent shifting out of park , if the brakes are not applied.
called park lock out.

Your neutral safety switch needs replacing.Here's the part. Duralast Neutral Safety Switch CR401 2004 Jeep Grand Cherokee 2WD 8...

Either you got the wrong neutral safety switch or it is installed incorrectly

Okay, wish you would of listed the code # but thats okay, the way you explained it sounds like the gear selector switch is bad, this switch is located on the side of ******, the computer and ****** think its in d3 this is cause most of the time 90% of the time to a bad selector switch also called a neutral safety switch,

replace switch reset codes and check ****** fluid , not sure how far you drove like this but if fluid is brunt i would have it flushed, not drain and fill but flushed, a BG flush.

I think with a flush and selector switch you will be all set, good day.

It may the neutral safety switch licated usually where on the front lower engine compartment ..they get full of crud sometimes and just need minor adjustment...

It sounds like your shifter cable may be out of adjustment, this is more common in chryslers, you may need to adjust the shifter to get it to start. also the neutral safety switch may be faulty. but when those go bad the car may not start at all.

try starting it in neutral.could be the neutral safety switch
