My 04 Infiniti FX35's trunk just went out after replacing all 4 door lock actuators haha! Dude, you've saved me thousands already. Thank you.

[@GQ37official]

Ah man glad this was helpful. Sorry to hear that you're having to replace all that, but if the original parts lasted that long you should be good to go for awhile! 😁

[@tolis296]

Thanks for the video man! I had the same issue, followed your advise, and it’s all fixed. I appreciate the time you put in that.

[@GQ37official]

awesome so glad to hear when one of my videos helps soneone! That's what it's about!

[@yellowtail58]

Thank You so much. Mine just started doing this "not opening when I need to put something in it.

[@loveispain..]

Thank you!!!

[@christineb2969]

I have an fx35 2010 and this just ahopened to me :/ so sad but i still took it on a trip to oregon from cali

[@kyleallen8253]

Thanks for doing these, just found your channel and a lot of the things are the same on my fx45. But I had a question, do you know what tail lights you have on your 35? because they don’t look like my stock ones.

[@kyleallen8253]

2003 45 btw

[@GQ37official]

Hey thanks glad some of these videos might be helpful. Yes those are the oem smoked twilights, they were a factory option, but a bit rare compared to the red ones most came with. Sometimes you can find them used on eBay. Same fit regardless if it's a FX35 or fx45 so it's an easy upgrade if you can get your hands on a set of ones in good condition. To me it makes a big difference on the rear end of the vehicle!

Hello Chris - does your FX suffer from the weak door actuator issue? Mine functions in cold(er) weather, but when it is warm the rears fail to unlock / lock sometimes. Also, what did you do with the crossbars for your roof rack? I've been looking for some for mine! (05 FX35)

[@GQ37official]

Thankfully no mine doesn't have that issue. I didn't take my crossbars off, I painted the roof rack and put it back on as it came.

[@da324]

I'm guessing this was an option? I just bought an 07 yesterday, one owner, garage kept, and mint for $5400.00. I do not hear a motor when I close the back and it has to be opened from the back from what I can tell. As with any vehicle I buy there's a learning curve figuring out where everything is and the different functions.. I've subscribed and I'm sure you'll save me some time at some point.

[@GQ37official]

Thanks for the sub. Not sure, I've owned 2 first gen fx35s, a base model 07 and this loaded 08 and both had the motor that would grab the hatch and pull it in another inch or so when closed. Honestly I always thought it was weird because any other car you just close the hatch, but on both of mine you close it and then it pulls it in just a tad more. No idea what the purpose is, but it's possible that yours went out, but as long as you can open and close it I wouldn't worry about it. 😁

[@michaelc1042]

Hello Chris, thank you for making this video. I have a 2012 FX35 and a 5 gal jug of water tipped over when I made a turn and started spilling into the cabin. I quickly pulled over and opened the back hatch using the hatch button to the left of the steering wheel and uprighted the jug, but only after a couple of gallons spilled out. Later that day, I tried opening my hatch with the same button, the key fob, and from the back of the car, nothing happened. Do you have any ideas on what I can do to troubleshoot this problem?

[@GQ37official]

Make sure you didn’t turn off the switch to open / close the hatch near the button under the steering wheel. I’ve done that before on my 2nd gen and thought it was broken. Otherwise it’s possible that something shorted with the hatch motor 🤷‍♂️

[@dawidwojtas9652]

Thanks a lot to be honest I'm doing exactly everything with my fx. I realized youtube and my skills are way better than lot of those days "car mechanic"

[@GQ37official]

Hey you bet, glad it was helpful!

[@ELEVOPR]

Did the faulty door latch drain your battery at some point? My alarm tells me my door latch is open, but the open door does not show on my dash and it is draining my battery within a day or two? The weird thing is mine open and closes fine and I can even hear it click. It's not the Alarm as the alarm was replaced and new as well Pretty Weird it's draining my battery since door is closed and locked. Seems easy enough to do, but it's getting cold here in NYC and I'm a little worried the plastic clips can break? cold plastic can become very brittle.

[@GQ37official]

Indeed the plastic clips are brittle as is so I understand. No, I never had an issue with battery drain when mine did this. Mine didn’t show door ajar, it just wouldn’t open when it failed. 🤷‍♂️

[@omarwahed9]

Hi Chris, I changed the lock and the trunk no longer suction.

[@GQ37official]

Strange. Does it open and close though? I’m wondering if not all fx latches we’re motorized so maybe the replacement you got isnt? 🤷‍♂️ not sure just grasping at straws

[@omarwahed9]

Yes, it closes and opens perfectly, i have another car i will change the lock and see if it work.

[@Kleanup_krew01]

Is there anyway you can tell me if there’s a door lock actuator fuse/relay for a 2005 Infiniti fx35 and it’s location?

[@GQ37official]

I'm not aware of a specific fuse just for the door locks. Usually it's the door lock actuators that go out. Unlike windows where mainly the front driver / passenger are used the most, it's more common for all the door lock actuators to go bad close to the same as the vehicle gets older.... they were all installed at the same time from the factory and thanks to remote door locks they get locked and unlocked about the same amount of time daily and tend to wear out at the same pace. Its a bit expensive to replace them all at the same time, but from what I've read that tends to be the fix. Let us know here if you find another work around.

[@martinmolina3670]

My 2015 QX60 hatch is not going up. It closes fine just won't open all the way when I push all the unlock buttons on the car. Any ideas on how I can fix it?

[@GQ37official]

so yours is motorized correct, you pull on the handle and then it will usually auto open? If so, can you manually raise it or is it stopping part way like it's getting stuck on something?

[@joepritchet6562]

So it slammed shut instead of closing on its own once it gets to a certain point of closing??

[@GQ37official]

Yes instead of the motor taking over once you shut it and sucking it in the rest of the way it didn't do that which is a sign that it's going out and one day you'll just go to open your hatch and it won't open from the outside, which is what happened to me

[@interstatebullly3nyg551]

Mines is doing the opposite it won’t close it stays open

[@MarkStephensonjahlovetech]

Hey Chris I seem to be having the same issue with my 2008 Infiniti fx35. however, if I removed the 15 amp fuse for the rear it works for about a few weeks to a month. then I have to repeat those same steps. Do you still think it's the rear latch motor needs replace? and also do you have the link to order the replacement motor. thanks

[@GQ37official]

Hi Mark that is a bit strange it seems more like an electrical issue than the motor if it works temporarily after replacing the fuse. Hard to say if replacing the motor would fix it as it doesn't sound like that's the issue. Might be worth having a dealership diagnose it even if you replace the part yourself to save money. As far as the latch motor actuator I bought mine off eBay. I didn't put a link in the video as it's not a mass quantity listing type part so once that part sells that link would no longer be good. However, if you want to get one I can find one and send you a link.

How you fold down and up rear seats on a infinity fx35 2005

[@GQ37official]

There's 2 ways, in the seat itself near the seat belt insert is a small plastic lever poking through the lower back portion of the crease (in between the seats) pull that up to move the seat back and forth. The other way is from the rear hatch if you're trying to lay them flat....there is a lever on each side Right and Left of the vehicle just under that small rear side window, it's usually a dark grey color, pull that and push the seats forward (or back if you want to recline it more) Hope that helps.

[@tunisiamckenzie]

I would have liked to see how you actually put the part in

[@GQ37official]

Sorry I only had 2 hands and was in the way of the tripod. At 6:05 as shown there are (3) 10mm bolts in front and one on the bottom plus the power supply, it comes out from the back and install the new on in reverse order. Thanks for watching

[@infiniti_fxvq4602]

Is that the actuator or just the motor

[@GQ37official]

It's both, motor and actuator all in one. Here's one on ebay like what I bought so you can get an up close look www.ebay.com/itm/03-08-INFINITI-FX35-FX45-REAR-HATCH-TRUNK-LIFTGATE-LOCK-LATCH-MOTOR-ACTUATOR/265104560526?epid=1522286380&hash=item3db976918e:g:bZAAAOSwO7Jf8QrZ

Anyone got ideas of what to do if you can’t open it? Mine the mechanism sounds like it’s working but there’s a zipper caught in it (I’m aware that it’s dumb). Doesn’t seem like I’d be able to disassemble while it’s closed.

[@GQ37official]

Will it open via the emergency release inside like I did around the 0:20 mark or is that stuck too? If that won’t open either I’m not sure how to get to it
