Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is ***** ***** welcome to just answers! I will be assisting you with all of your vehicle questions today. Give me one moment while I review your question and come back with a answer. Please be aware I do not know your skill level or abilities so I will be asking a lot of questions and in a lot of cases we will respond to each other quite a lot before we find a solution. As far as phone calls are concerned that is the system prompting you, not me, and they do cost more money, I prefer text but in some cases a phone call is required. If I don’t answer right away or quickly in conversation I am helping another customer or have stepped out for a moment and will respond as soon as I can. Ok lets get started!
Will the trunk open any other way?
do you have a volt meter?
Pull that relay and check for ground signal on 3 when hitting the unlock button
you want it to be on d.c 20 and have the positive red lead on a known good 12v source and check the 3 with the black lead when hotting the button
do you get 12v?
ok so your getting signal to the motor, so if you have power on 3 and 1 then you need a relay
have you tried bench testing the relay that you got?
try bench testing the old one and see how it does
the power probe is something good to have as well, you can get a older one for cheap and it will do all of that for you
so something is going on with the signal to the relay not enough power or no good ground, the ecm send signal to the relay which is a ground, and the top 3 1 are the power and 2 is the signal and 5 is the supply to the motor to open the door
