OK, Bought a 07 with a couple problems today.

[SpareParts]

This time of year doing this work really 5uck5 though. Cold, Damp and breezy.
Had to put it in the quad shed to get mostly out of the weather
Used a Schrader valve hookup and buckets to get that tank empty using the fuel pump jumped at the relay.
Have no idea why i used 5 gallon buckets. I have 4 empty 5 gallon gas jugs in the garden shed.

A lil off topic but i got this picture at work a few weeks ago.

Like the new light setup! I’m a fan of the wrap about tube style LEDs and projectors on this truck. But yeah LEFs can for sure be tricky if the projector isn’t designed for it.

For what it’s worth I run Morimoto LEDs along with their bi-xenon projector setups retrofitted. I spent a good chunk of change but worth every penny in my opinion as I live in the mountains and the highways leaving in and out are pretty dark with no street lighting. They scatter the light and have good beam patterns, but it’s really usable and when I run my highbeams along with the projectors, there’s tons of usable light coming off the truck for the Mountain highways. Just my $.2…. lol

you work in aviation? That’s cool.

Yeah, Guilty as charged.

My fuel gauge sender stopped working a few weeks ago and now the gauge just reads empty and no remote stat cuz it thinks it out of gas.
Getting the tank out is actually not a bad job at all. Now that i have it out and know how to do it i think i could do it in about an hour
I was really dreading doing it as all you see is how bad a job it is and a PITA, but it's really not.
The bummer is i ordered the GM replacement sender and it does not fit as my fuel pump is a Delphi so have to return that to Rock Auto. Leaving me with the only choice of purchasing a complete fuel pump from Orilley's as i need my truck running but it will not be here till tomorrow around noon.

See post #81 above,
and see

mine is consistant with each tank of fuel so I'm starting to think its the stepper/driver for that gauge, not a chaffed/loose wire
good luck

I have about 1000 hrs pic in Piper Malibu

Could be the stepper motor. I would change it if i knew for sure the sender is good.
My sender is for sure bad. The two little wiper arm things that run across the traces are worn out and one is pretty much missing.
Never got into motor homes myself but it does look like you are doing a great job! I do have a 98 Express high top van i made into a camper van for the wife and i as in the summer i spend a lot of time in the woods.
I'm pretty much tired of aircraft. After working Here for almost 20 years all i really wanna do is just buy old sh*tty Chevy’s do a little work to em and sell em on my schedule.

Got the new fuel pump installed and the tank back in. Took about 45 minutes, so not bad.
Fuel gauge now work and so does remote start!

Been checking oil pressure once a week since i changed the oil pump and O ring. Seems to have stabilized at 23ish psi at hot idle but will continue to monitor it.

Remember when i said i could not hear the chimes and suspected blown speakers?
After the fuel pump was done, i figured it was a perfect time to swap them out and put the new ones in. Now both front door speakers work and i hear chimes.
Stereo sounds better and fuller now. I do have the UQA+Y91 9ch + Sub Woofer Bose system.
Check out the pic. Explains perfectly why i could not hear chimes and thought the speakers were blown. PO removed both of them.

 

[SpareParts]

Couple questions.
When i put it in reverse the radio switches to the reverse cam, but there are no guidelines. The wife's 2014 Avalanche has guidelines when her reverse cam is on
Did the 2007 year not have that?

I do not have courtesy lights when the door opens on both front doors. The inside has a red reflector but no bulb housing and no wiring i can find for one. There is also no light on the bottom of either mirror and no spot for them to even have a light. Anyone know where they are supposed to be on a 2007 Denali XL?

 

[Grady_Wilson]

My 2011 Yukon Denali has no lines in the backup camera, no door courtesy lights, but it does have courtesy lights on the mirrors.

 

[SpareParts]

From what i can tell, it looks like the PO changed the mirrors out for ones without the paddle lights on the mirrors for some reason.
Every part's diagram i look at shows paddle lights. Just seems odd to me.

For the first time since I bought this Yukon about two months ago I have repaired every system that was causing warning lights on the dash.

 

[SpareParts]

Up in the woods today as far as i dare go by my self with no tools or recovery gear just to get an idea of how this Yukon handles winter stuff.
Seems to do alright for the little i could work it, but there is for sure a need to raise it up a few more inches.
I would imagine with over 200k the stock springs are sagging. Front struts seem to be too stiff. Can't decide if rear is too stiff or about right.
I think i want Bilstein 4600 struts and springs on the front. From previous experience with them, i really like the ride they provide. Probably Moog springs.
No sure about the rear. I want to keep the air shocks on it because i do pull a trailer with a 450LB tongue weight and a couple of hundred pounds of stuff in the back, but i don't believe Bilstein makes 4600 air shocks.
Any suggestions on a set of air shocks that have a ride feel like Bilsteins?

 

[SpareParts]

Now that i have the new TPSM sensors installed the warning pressure seems to be set to high.
At anything less than 40PSI, the light comes on and tells me to check tire pressure.
I like to run my fronts at 35PSI and rears at 32PSI unloaded. When pulling a trailer and hauling stuff around i do increase the pressure.
Anyone know how to lower the warning threshold pressure to something more reasonable?

 

[SpareParts]

Two days of searching trying to figure out how to adjust it and can't find out how. Make a post and do another search and bang find the answer on here.
Using my Snap on, Solus Pro and digging around in the menu's i was able to adjust tire type and pressure.

Since it was 30 degrees out today, foggy and not raining or windy, I thought i would get some tinkering done today.
Had a broken bolt on the DR side sway bar mount and fixed that today finally. Had to drill it out and replace with a nut and bolt. Grade 8 hardware was used.
Looking around at what else i might find i wanted to mess with and started looking at why my rear defroster was not working.
I had already checked the plug behind the head liner and it was all good so i knew that was not the problem.
Found 1 tab that someone had tried repairing with superglue, i think. Anyway, i tugged it a little and it popped right off. Nice found the problem!
Looking for a way to fix it and i ran across a video showing how to solder it back on. SCARY!
After watching another video of a guy showing how much heat the rear glass can take i decided to try it. Figured what the heck. I know where i can get another one for $30 so why not.
After cleaning everything up really good and putting a little solder on the tab, i used a heat gun to heat the glass up till it was warm about 12 inches around the tab mount.
I then held the tab in place and put the solder iron to it. Took about 5 seconds and the solder melted on one side, moved to the other and within seconds the tab was soldered back on. Let it cool for a minute or so and checked it with a DVM and i had continuity between the tab and heater grid.
Started the truck and turned the rear defrost on. After about 10 minutes using an infrared temp sensor i checked it to see if it had a hot spot from not being attached good enough.
The repaired side was more or less 5 degrees hotter at the tab so i believe it is good. If it does not shatter tomorrow on the way to work it will be a success and 0 dollar fix.
Here is the Video.

If that doesn't hold try https://frostfighter.com/

 

[SpareParts]

It will hold I'm sure.
The only problem i can see is if the contact area is making a partial contact causing a hot spot, in turn causing the rear window to shatter.
I looked at frost fighter and it for sure seems like a viable option.

 

[SpareParts]

The rear defrost works fine after the fix. I have used it a couple time with no problems.
Lots more i wanna do but with the weather the way it is kinda just collecting parts here and there, So to that end.

Got lucky as he11 today with a score on EBay. Was searching newly listed 2007 Yukon Denali EX parts and found a set of NOS front struts still in GM box for $120 and for that price ill risk it.
Gonna have two weeks worth of work piled up for when the weather gets nice enough to work outside again!
