How to bypass neutral safety switch on Saab 9-5

I would say yes. Replacing the nuetral safety switch should correct both issues.

Your safety interlock switch is going out or is not adjusted properly. There is a procedure for adjusting the switch. The switch is on the transmission in the engine compartment. If you want to adjust the switch, loosen the botls holding the switch and follow steps 7-8 below. Else, you can just replace the switch entirely by following all steps.

The neutral start and backup switch are one unit mounted on the top left end of the transaxle. The neutral start portion of the switch allows electrical current to travel to the ignition system when the shift selector is in park or neutral only. The vehicle will not start when the selector is in any other gear. The backup portion operates the rear backup lamps when selector is in the reverse gear.

REMOVAL & INSTALLATION See Figures 1 and 2

1. Make sure the shift selector in the Park position, then apply the emergency brake.
2. Disconnect the negative battery cable.
3. Disengage the neutral start switch electrical connector, then remove the shift control lever on top of the switch.
4. Remove the two neutral switch attaching bolts, then remove the switch.

To install:

1. Install the switch on the manual shaft.
2. Loosely install the two attaching bolts and washers.
3. Insert a No. 43 drill (0.089 in.) through the hole.
4. Tighten the attaching bolts to 7-9 ft. lbs. (9-12 Nm), then remove the drill.
5. Engage the switch electrical connector, then connect the negative battery cable.

1. I tried to find a

   If you go to your library you can look for free. Just not sure of location of of neutral safety switch for your year of car. In the back of motor manual is wire diagrams you will find switch there. Also GEO Prism is the same car.
   
2. The last time I worked on a Prism it was a 1997 I found a bad wire connection at the shifter. Took 20 minutes to do repair and no parts.
   
3. So I would check the switch in your console. Sometime they stick or a wire comes loose. Sometimes a little WD-40 shot to the switch helps.
   

would advise against trying to bypass park switch try ajusting first

try to start it in neutral. the trans. has a safety switch that will not allow the car to start in anything, but park and neutral. sometimes the shift lever gets a little out of line with the gear indicator. also try firmly shifting into and out of park a few times. this may flip the switch. good luck

Sounds like a neutral safety switch. Replace it & try again.

Is your SAAB automatic? If so, it is most likely the Neutral Safety Switch. I have had the same problem, it is very common in automatic Saab 9-3 models made in 1999-2002.

e the neutral safety switch looked at....it should start in neutral anytime you have this problem.

Check the adjustment on the nuetral safety switch on the transmission, if that doesn't fix the issue replace the neutral safety switch.

I'm not sure what you mean by "neutral safety switch". I have the shop manual for this car (I also have a 2001) and there is nothing listed under "neutral" or "safety" or "switch" in the index that looks like it.
