Good morning guys this is voice to text so I apologize for any years I have a 2007 Escalade and I'm wondering is there a link in here for the service manual for that year of trucks I'm looking for some wiring diagrams as I'm trying to prepare for safety check and I'm running into a few problems I understand it's a can bus I'm not worried about that I just like to see some of the other wiring for for stuff so if anybody can help me great and if we don't have that that's fine too I will Mosey long the biggest problem I have right now is the liftgate will not open I see the lights blink I don't hear anything happening yet a week and a half ago it was working but I can't close my garage door with it open so I simply close the the trunk and now I can't open the freaking thing and I don't hear anything happening I was doing some wiring and I I ripped up all the floorboards where I'd worked and I see nothing I touch because I made sure I don't have any blown fuses I just trying to use the fob when I use the switch up on the ceiling I hear nothing and the switch when I operate it in different modes there's nothing happening the switch in the handle I guess have been broken for a very long time I can open the rear window and close it no problem everything else seems to working but the tailgate so anyway I just need some wiring diagrams thanks guys

Thanks my friend. Tailgate was working now it blinks the taillights but no noise from tailgate. Thank you for the link
2007 escalade getting ready for safety
Ok in the hope that someone else has seen this, unit on jackstands in the garage. Unable to open liftgate. Opened it after much despair flicking the liftgate latch. So on remote taillights blink once but no sound from actuator. Fuse 44 underhood is good but no power appears on fuse when the embedded relay in the fuse box when the relay closes, ok after screwing around for hous I then applied 12v to the other side of the fuse and still nothing.Overhead console switch does nothing and is turned on. Rear hatch glass opens ok.Now still not having a good set of electrical drawings I can. See the motor for the latch uses a pwm of sorts to actuate. It all worked going intoxicated the shop but of course me with needle scaler walked things up. Now the simplest is the most likely but I am scratching my head how does the impeded relay go bad and nothing happen on the other end when I apply power to the other side of the fuse.checked wiring, pulled bcm and reinstalled, no blown fuses just no action. So if anyone has had something similar. Now out of work so I ain't buying no parts. So I intend to put it backtogether and start again. Looking at a drawing today that should be close, 12 v comes from relay to fuse then to the rear to the motor then thru all the contacts and the bcm should execute. I am still trying to get a set of drawings I can print cause trying to squint at a cell phone is not my thing. I have not tried starting the truck but the door locks lights all seem to work just this blessed tailgate latch. I know they go bad but there is no voltage getting to it from the underhood fuse box. 07 escalade sorry to be so long stressful day job hunting and trying to get this working plus trees down from the storm couple of days past.......I do not want to destroy fuse box trying to figure out what is wrong....
