Where is the neutral safety switch? 67

Gents:
I had my car (underside) steam cleaned Saturday and they did a great job, drove home fine, however, now the car will not start, I checked all the usual stuff from the wiriing to the starter, ground, solenoid, etc... I am down to the neutral safety switch. I have read all the posts I can find, none of which describe where the switch is and how to check it for proper installation? ( I did find out how to bypass it, if I could only find it :-) I assume it is mechanical and adjusted to the shift lever, but not sure. If there are posts here that answer this question, maybe I just don't know how to search the forum? any suggestions at this point would be helpful, thanks.

Re: Where is the neutral safety switch? 67

Need a little more info, like what transmission (I assume it is an automatic, as manuals do not have an NSS) and what shifter you have.

If it is an OE Powerglide style floor shifter, then the NSS is inside the car at the base of the shifter lever. See the pics in the linked auction:

If it is an OE shifter, there's really no way for the underside steam cleaning to have affect the switch, unless the rubber boot underneath is leaky.

If it is some other kind of shifter, we'll have to know what you have before we can help.

Re: Where is the neutral safety switch? 67

it is an original console shifter for a powerglide, I swapped the PG out for a 350turbo last month. It sure seems to be a neutral safety switch issue. The only thin I have not checked is the 12v coming from the ignition to the starter, ( whcih I assume would be 0V in the case of a bad Neutral safety switch or as a very last option, the ignition switch itself) The starter kicks over when I jump it and when i apply 12v to the small lug on the Solenoid.

You can bypass it with a jumper wire as a test. It's the 2 purple wires on the four wire connector at the console shifter. cover it with electrical tape of course.

but don't do that permanently - just to test.
Then your car will start while in gear, and that is dangerous.

The original switches can be carefully repaired if needed,
or just buy a new one - they are reproducing these - $29.00

Unless you are converting your car to a stick like I did.

Tom,

Just be careful to not start your car in gear. You do it once and never forget.

The first time I realized my '67 RS didn't have a NSS, I almost freaked out but thankfully I had plenty of room so stop the car.

Gotta get together now that this rain is finally over.

Hey Oakster,

How's it going? I learned to drive on a 64 vette. They didn't have neutral safety switches either. I make damn sure the clutch is in!

Mine is in pieces but back together in April. Hope we can hit Chop Shop again together.
