I have a 2004 g35 coupe. recently my trunk latch button on the key fob didnt work so i then went to the switch on the dash n that didnt work either. So i figured it was the accuator in the trunk latch so i replaced the entire latch assem but still no luck. I back tracked and checked out the fuses both under the drivers side dash and also under the hood in the battery area. All fuses work but replaced all the 10's n 15's to make sure. Nothing. Im wondering if this is common?? im thinking now that a possible short to ground somewhere? All other electrical components operate correctly besides this latch. The car didnt have any work done too it prevously so i can rule this out. any ideas or advace would help. Thanks

 

I'M HAVING THE SAME PROBLEM!!! The first day I got it.. it worked fine. Now and the previous 7 days I had it.. it doesn't work at all!

 

Check the glove box for an on-off switch, the sedans have one, maybe the coupes do too

 

wow wtf! same thing here with my 04, first 2 months okay, but now its slowly going going and then gone. i have to un hook my negative and re hook again everytime i want it to work with the key fod,
my dash button never worked though

 

My '03s key fod doesn't even have a trunk button!

 

I had the same problem and found the wires for the latch and light were both split. The harness from the body to the trunk lid is the issue the wires rub and end up breaking from the repeated opening/closing of the trunk. You are going to need to cut the rubber harness protector open, on the right side of the trunk, and find and resplice the wires.

 

Okay thanks! ill give that a try today

 

didnt even think about looking at the switch in the glove box. i do have one but this is why i post to get reminded lol thanks. but also w/ the harness to the trunk that seems like a good idea. i will look into that. thanks for your responces hopefully they work.

 

What does the on/off switch do? I just checked mine and it was off.

 

Its an easy replacement to fix the solenoid actuator if thats what it is.... (2) 10mm bolts and a electrical connector.

 

i have a button (switch) left side of steering wheel beside the dimmer wheel, whats that do? following the glove compartment

 

are all the wires to the latch plugged in snug? they could be loose

 

that sucks. These are like safes!
