- First off I want to say this is a great vehicle. The engine is good for 300,000 miles easy. Parts are cheap also.

Unlock Relay shorted out. Part 8867. I'm going to replace both the lock and unlock relays. I may also have to replace the entire Dash fuse box. Unfortunately I replaced the liftgate actuator for no reason but it was only 15.00.
This part is common to GMC Suburbans Yukons also. Hope this helps leave comments below
Lifesaver! Replaced both relays Lock & Unlock. Works like a charm. Napa part # AR172 replaces GM 8867 . $37 fix! Thanks for the video🤙🏽
Thank you....bought the whole unit(138.00)....didn’t open it out of sealed bag so you saved me ..,it was burnt!
Thanks for the tech support! I just changed the two in my 2004 Suburban, Works great again. I love my Suburban..........it just keeps on a'truckin'
Is there a way to test the relays the way that you can test to see if a fuse is blown. Or did you just go and buy two new relays?
I just "shotgunned" it. Bought two new relays and plugged them in. Got lucky. They were cheap on eBay.
@@karlgruber3973 I think the guy who made the video said this won't work if the back door still locks & unlocks.
This only works if the back lift gate only, is broke.
It fixed both my back doors and rear lift.@@do7hemath937
Thanks for the video. Switched out relay with another one and it worked. Saved me time from tearing Tahoe apart!
Glad it helped
Great video. Thanks for the help. 👍👍
thanks..you saved me alot of headaches!!
This helped me out alot thanks
Great post. Thanks
Thank you !! It worked!!
Thanks
Thanks for the video.
Thanks 👍
So I noticed both of mine are in good condition and the ofther fuse for the tail gate is good also, what else can cause this to not open the tailgate or rear door I. General
@@joseserna4918 swap them around. See if problem moves with the relay. Has to be bad relay. Just find it is the issue usually.
Did you fix it yet? Did you replace the fuse box or did new fuses/relays work?
My actuator went out, I replaced that. And after a full day of working correctly, it stopped . Then my dash. Said “replace tailgate fuse.” And here I am. Ordered 2 new relays and waiting for them to come in
Yes. The relay was inserted in the wrong slot and shorted. New relay fixed it. This is the relay panel at the driver side door.
MegaHowtoMan wheeew , that was a cheap fix for you then instead of replacing the whole fuse box due to that area being fried...ya mine is in the same area and requires 2 relays, should be here in a few days and we’ll see if it fixes my problem
@@B_HarTzis there a a way to test the relays like testing fuses with a digital multimeter?
Is it possible for the relay to fail in a way where it ONLY affects the hatch lock and hatch glass lock? Or does it always affect the rear doors also? Idk if I should order a relay or a lock actuator both gonna take like 2-3 weeks to get here.
If your rear door locks still work it's the latch actuator. The relay is cheap so get one anyway.
@@MegaHowtoMan thanks for the quick reply I didnt even realize u relplied so early. Yeah I did order a new actuator and got it put on last weekend my liftgate works again!
I've had my Tahoe for 10 years and this is the 2nd time that the liftgate/ hatch has stopped unlocking. The back & passenger door unlock fine.
The first time I took it to a repair shop & they charged ALOT to take the panel off & replace the actuator in the lift gate.
Now I'm going to try this 1st.
The weird thing is on my way home from work, I got in the truck and literally heard a noise in the back of the truck when I turned the ignition to on. Almost like a popping sound.
might wanna show where exactly.....think I see where I think it came from. So did replacing it work?
Where the relays& fuses go are inside the fuse panel.
Could those relays cause battery drain?
Yes. I had a battery drain from the drivers power seat adjustment and the aftermarket car stereo.
Do you know what caused the relay to catch fire?
Someone plugged it the wrong slot!
Does it take two batteries for lift gate to work in a Tahoe
It works off of the electricity from your car battery.
Which relay was it?
Were you able to fix the problem?
I changed the relay and the actuator but it the trunk door or lift gate still don’t work
My relays look fine but the lift gate actuator doesn't work. I replaced the actuator thinking that was the issue and unfortunately it wasn't.
@@sergiopereziii hey i figured it out, the little spring on the handle for the trunk door rests under the white lever looking thingy, so make sure it's well placed.
@@paramiamigo5520please explain
I’ve changed it out twice now keeps melting 🤷♀️
Start looking for a bared grounded wire or shorted out motor
