if you look under the dash at your brake pedal if automatic trans,and if its standard look at the clutch pedal and look for the switch,this is not a hard job to do but it will take patience.
the neutral safty switch is located in the trans range switch if you have an aw4 auto trans replace or clean and reinstall the switch
It only allows starting in park and neutral and it turns on the reverse lights.
It is on the valve body inside the transmission.
find the conector(s) and jump it. also try starting your vehicle in neutral.
It is inside the transmission, on the valve body. It is called a range sensor.
You might want to check your park-neutral safety switch, if it is not engaged the starter will not run.
Usually it is located on the shifter inside the console. You have to disassemle the console around the shifter to get to it.
Trouble code P1899 means: Park/ Neutral switch stuck in park or gear
Problem solved...the culprit was bare neutral switch wires shorting out and blowing the fuse!!!!!
How do I replace water pump on 2004 jeep grand Cherokee
either behind or in front of the arm of your brake pedal. Follow the brake pedal up until you find a box, either in front of or behind the brake pedal. You will find that the box has a button on it that is activated by your brake pedal, that is the neutral safety switch.
if it is a jeep Cherokee it needs a neutral safety switch mounted on the passenger side of the transmission. if it is a jeep grand Cherokee it needs the backup switch located on the drvers side of the transmission
