also what happens if you don't disconnect the battery?

[FoxInSoxx28]

@evilcowboy the alignment issue could be from installing the arm that connects to the NSS backwards. You should be able to rotate the arm all the way forward and push the shifter into park and everything will align. As far as battery, by not disconnecting you run several risks, worst being personal injury by electric current or damaging other electronic components or connections by shorting your wires.

@FoxInSoxx28 ahhh yeah found out that the little bit of messing around cause the cable to stretch and break I can't shift any higher than D3 and can't shift back down at all. So I'm fixing the cable this friday. I guess it was a stroke of luck that my cable snapped for me lol. But at least I have backup lights now lol.

@FoxInSoxx28 well I found out that I installed everything correctly. I was just fortunate enough that my cable was old and broke just from the little bit of movement it had. So after replacing the shift cable it works just fine and I have backups. It should also be noted the plugs for this switch is glued in which is what makes them so tough to remove. I had to crack the plastic around the plug to get mine free as well.

I am undergoing this replacement and got a couple questions. Is the metal thing on the front of the NSS indicating neutral or park? I got back lights but I didn't align the shifter cable right and now I can't get into P or R any help with the alignment of this thing in conjunction with the shifter cable since with the cable disconnected I can't feel where neutral is any help is appreciated.

@tde5 sound like a wiring issue and pinpointing exactly where it's coming from could take some more testing or a mechanic. I'm 99% sure that the signal going to your column indicators comes from the NSS, but it could just be turning onto one of those old trucks with old quirks. If worse comes to worse, One suggestion is to wire a toggle switch in your cab directly to your reverse lights and not worry about the NSS control at all.

Hey, your video popped up in my google search results for NSS info. The reverse / backup lights on my 99 Suburban do not light up at all. No problems with any other lights or directionals, checked the fuses, and replaced the bulbs - still won't work. Shifting into reverse and backing up is fine as well, just the bulbs. Someone suggested it may be a bad NSS, but I don't have any issues with switching any gears or starting up. Does this sound like it could be related to a bad NSS?

[FoxInSoxx28]

@tde83 could be the NSS in the 98 models there is a lt green wire that runs from the NSS to the reverse lamps, not sure what color wire is going into the switch is off the top of my head, but a haynes manual or exterior electrical chart will solve that. I suggest starting there: apply the parking brake, drop it in reverse and check to see if you are getting signal with the incoming wire with a multimeter, if yes and no signal is coming out the NSS it's a pretty good bet.

[FoxInSoxx28]

@tde83 before you do that, trace the lt. green wire from the NSS to the tail lights, could also be where the wire splits to hit both L and R lights has disconnected. Then all you need is a coupler and some electrical tape :) good luck.

[tde83]

@FoxInSoxx28 hey, thanks! I will check it out as soon as it isn't pouring here. Hopefully whatever it is is a simple fix.

[tde5]

@FoxInSoxx28

Thanks again for the tips. I did try to check the wires but didn't encounter any problems, so I replaced the NSS. Still no back up lights, however now I don't have the indicator PRND321 lights on my dash to indicate what gear I'm in?? What did I do to screw that up? did check the fuses too. Everything else is as it was before the NSS replacement. Car shifts as it should, as well. Thanks.

@FoxInSoxx28

Hi again - I noticed yesterday the tailgate trunk latch/release button no longer works. As a safety feature, it does not pop the trunk unless the truck is off and/or in park, so I'm guessing this means I DID install the NSS incorrectly, but I'm not sure what I did wrong. As I mentioned previously, the indicator lights under the PRND are out after NSS replacement. Is it possible the NSS wasn't "all the way" in neutral when I installed it or the plugs not re-inserted all the way?

[FoxInSoxx28]

@tde5 could be a bad replacement NSS or the wires were not pushed in securely. i'm actually shocked that your truck is running with the bad switch installed, it's actually not supposed to start without a verified signal from the NSS. The switch tells the dash what gear to light up, that's why alignment is key, once you have signal going to your dash, you'd be able to figure out if it is misaligned. If I had to guess, you ended up with a bad replacement switch or you need to recheck your wires.

thank you for the tips it was the NSSwitch that was giving me the problem..I did forgot to disconnect the battery when installing the nnswitch. It would not start so i disconnected the battery and after 10 mins, I connected the battery and turn the key forward and left it turned for 5 mins and it reprogram itself and started right up.. Thank you again..

[Raybajosexto007]

my 2002 chevy silverado will start fine and after running the truck for an hour or so, i'll turn off the truck and it won't crank no more till 15 or 20 mins later..Sometimes when i move the shift to 3 gear and back up to park and hold it, it will crank..could this be the nsswitch also? Appreciate any tips..thk you..

[FoxInSoxx28]

@Raybajosexto007 could be, or just could be a bad connection in the electrical in general. Start by getting a multimeter and a wiring digram and test your connections. the diagram will give you the colors of wires you should be looking for. jack the car up, apply the parking break, put it in drive... if you have a no crank issue, use the multimeter to check that you are getting signal from the wire that runs to your starter relay switch. other problems could be your starter switch or keylock.

[FoxInSoxx28]

@Raybajosexto007 sorry in my last statement, i said put in drive... i meant put in park or neutral.

[JUDGERAMBO]

Was this truck hard to start with the bad switch?

[FoxInSoxx28]

@JUDGERAMBO still trying to figure out what's causing my problem. The truck will not crank at all but if i wait a day or two after running it, it cranks fine. I was told by several mechanics that it could be one of several problems and received a giant list of possible solutions... If your NSS is bad, your starter will not receive a signal from the relay, so there will be no crank at all in neutral or park. It is a safety feature to make sure you don't start your car in gear.
