How do you adjust the neutral safety switch on a 1999 jeep Cherokee?

Answer 1

On an automatic 1997 Jeep Cherokee with the inline 6 cyl 4.0L the neutral switch is combined with the Park and reverse switch. To repair the switch, unplug the harness from the top of the engine near the transmission dip stick. The switch is located on the passenger side of the transmission, right on the side. There is a bolt and a nut which must be removed, the bolt is for adjustment of the switch position and is near the top. The larger nut (Collet type) is near the bottom and is centered over an oval shaped shaft protruding from the transmission... BE WARNED!!!! these switches are VERY EXPENSIVE (~$160)!!!! so tread carefully and try not to break it. Mine was seized to the shaft and broke into about 8 pieces, luckily I have the know how to be able to repair them. You can free up the switch from the shaft with penetrating oil and pry against the loosened nut with a screwdriver while taping lightly on the shaft to back the switch off of the shaft. Inside the switch there is a problem where the grease gells over time and the wiper contacts stick away from the base contacts therefore they do not always make connection. Once you get the switch off in one piece, it is easily serviced by removing the screws on the back and slowly opening the case. Some of my screws were frozen and I had to break them off and drill out the holes, you may be lucky and get the screws out without this problem. When you have the switch apart I suggest you use a clean surface and put some cardboard down to catch any parts that fall out. Once open, you will see 2 copper wipe plates on the wiper arm, slowly remove them and under them you will see a spring for each side. Clean all the surfaces with brake cleaner or WD-40, you can burnish the contacts with a very fine 340 grit sandpaper. Once done reassemble putting a VERY thin layer of grease on the contacts to help prevent corrosion and allow the contacts to slide easier. Once you have put the module/switch back on make sure that the adjuster bolt is set in the right place... Put it on and make sure the reverse lights come on and it cranks in park. Tighten the adjuster bolt and put the nut back on and double check. NOTE: make sure you plug the harness back in or nothing will work lol. I want to add that the hardest part is getting the switch off. When you remove the Collet nut be sure to release it first by prying back the tabs on the retaining nut. (Note: when reinstalling, this nut is to be re-tightened to ONLY 5 INCH pounds!) After removal of the Collet nut, spray some parts buster or WD-40 onto the shaft area and let it sit. Put the Collet nut back on but not all the way tight and use a screw driver to pry the unit forward from the shaft SLOWLY!. Don't get carried away when it starts moving. When reinstalling put some never seize on the tranny output shaft in case you have to do this in the future.

To change the neutral safety switch, also known as sensor in a 2000 Mazda, park the car on a flat ground, turn the car off and put on the E-brakes. Disconnect the power begins with a negative cable then the positive cable and takes off the battery clamp. Disconnect the plug and the shifter cable then loosen the 22mm nut on the sensor. Remove the washer and the linkage then remove the neutral safety switch directly upwards. Replace the new sensor and repeat the reverse process by tying the plug back then the shifter cable, and then the battery plate, and you it's done.

Easy cheese!

loosen top bolt and rotate, block wheels, turn ignition on and put trans in R

adjust switch until reverse lights come on.

your switch is probably dirty.

heres how to clean it.

On the passengers side of the trans about even with the front of the door fan shaped switch held on by two bolts.

I suggest taking it apart and cleaning it before you think about replacing.

The switch is nearly $300

To remove, flatten out the retaining washer side under nut, remove large nut, remove smaller ( 14mm ) bolt on the adjustment side. Connector for the wires is top left of engine at the firewall, black connector with about 8 wires, you will need to snip 3 or so zip ties to get it free.

cleaning is easy, 6 screws in back, pull apart, clean out all that old grease, pay special attention to the two contacts on the sweeper arm, they should move in and out easily as they have springs underneath and are the man contacts, apply new di-electric grease and reassemble.

reassemble and align before tightening, easiest way is to put trans selector in R and move switch until reverse lights come on.
