Usamedic Posted November 29, 2014 Share Posted November 29, 2014 87 comanche chief, earlier today I was replacing some light bulbs on the rear taillights. I've never really had reverse lights, but had the wife give it a shot. I had one on! The left one, since the right side was all opened up I replaced the reverse bulb on the side and bam! Now I have two working reverse lights! We tried it a couple times and they continued to work. About an hour later I pulled it out of the garage, and we tried it again..... Nothing! .........???? Where the hell is the sensor, or switch? Is it electrical or mechanical/ over electrical? Link to comment Share on other sites More sharing options...
Jeep Driver Posted November 29, 2014 Share Posted November 29, 2014 If it's an auto it's a part of the NSS......neutral safety switch. You need to take it apart and clean it. Link to comment Share on other sites More sharing options...

Jeep Driver Posted November 29, 2014 Share Posted November 29, 2014 Looks like this- http://www.1aauto.com/jeep-neutral-safety-switch/i/1azns00006?f=493428&y=1990&utm_campaign=gb_csv_br&utm_content=ZNS&gclid=CjwKEAiA1-CjBRDOhIr_-vPDvQYSJAB48SmEiK8vs9aTEGpXys848xn3f_RQna3v3oEZLoUElBuh5BoCfmvw_wcB There is a write up here somewhere on it.....I'm sure.

Usamedic Posted November 29, 2014 Author Share Posted November 29, 2014 Interestingly the power comfort switch in intermittent. Usually not working. Today when the reverse light were working, so was the power comfort switch. Link to comment Share on other sites More sharing options...
Usamedic Posted November 29, 2014 Author Share Posted November 29, 2014 I'm finally tracing the last few current electrical gremlins, if the switch is bad, could it affect the the power comfort switches electrical Link to comment Share on other sites More sharing options...
HOrnbrod Posted November 29, 2014 Share Posted November 29, 2014 Highly unlikely. What is it doing to make you think the POWER/COMFORT switch is intermittent? Link to comment Share on other sites More sharing options...
Usamedic Posted November 29, 2014 Author Share Posted November 29, 2014 It general will not work, but I always leave it on because occasionally the damn thing will light up and work like a champ. The last couple days it's been on and working(ie you can feel the difference when you actuate it on or off). It was on when we were checking the reverse lights, and when they quit working so did the power comfort switch. All grounds on the vehicle have been upgraded and replaced, I'm running dual batteries and a 150 amp alternator.other than these couple little issues I've ironed out everything else but the interior dome lights. By the way, anyone got a set of those dome lights? Lol Link to comment Share on other sites More sharing options...
HOrnbrod Posted November 29, 2014 Share Posted November 29, 2014 Hard wire the power/comfort switch to power, then try again. You don't need the comfort switch position. http://comancheclub.com/topic/43938-new-aw4-power-power-switch/?hl=switch Link to comment Share on other sites More sharing options...
Usamedic Posted November 29, 2014 Author Share Posted November 29, 2014 Gonna try that tomorrow between rainstorms. Link to comment Share on other sites More sharing options...
cruiser54 Posted November 29, 2014 Share Posted November 29, 2014 Interestingly the power comfort switch in intermittent. Usually not working. Today when the reverse light were working, so was the power comfort switch. That's because the Power/Comfort switch and reverse lights share the same 7.5 amp "trans" fuse in the fusebox........

cruiser54 Posted November 29, 2014 Share Posted November 29, 2014 Here: Bypassing the Power/Comfort Switch on a Renix Jeep Remove and unplug the switch. In the harness are 3 wires One has a stripe, one is tan, and the other black. Make a 4" jumper wire with a male spade at each end. Plug one end in the cavity for the tan wire and the other in the cavity for the striped wire and you'll be in permanent Power mode. Stuff the harness back in and reinstall the switch for looks. If you happen to have a 91 or 92 XJ/MJ and it has the Power/Comfort switch, just jumper the Tan and Blue wires in the harness plug. NEVER include the black wire when jumpering!!!

HOrnbrod Posted November 29, 2014 Share Posted November 29, 2014 That's because the Power/Comfort switch and reverse lights share the same 7.5 amp "trans" fuse in the fusebox........ Yep, true for Renix. The HO's however have a separate 15A fuse for the reverse lights in the PDC. Link to comment Share on other sites More sharing options...
