Rivnuts and 2010 Suburban Roof Racks

Hola future people repairing your car.

Again a post for posterity.

Working on a 2010 Suburban that has holes to mount a roof rack but no hardware. I order the hardware (some weird nuts) and it isn’t clear how to mount them.

Turns out they are “rivets” – rivets that are threaded inside to accept a nut. Just get a rivnut gun, mount the nuts, and presto, you can install your rack. Pictures forthcoming.

 

Strangely, this information was not available anywhere on the web and it took me some time to figure it out.

I am just starting a blog to have a place to post things I’ve learned in hopes that someone may find them useful. The picture below has nothing to do with anything and was posted by WordPress.

Ok, so my 2004 Suburban 6.0 K2500 went into Reduced Power Mode – no throttle response and no power and couldn’t get it up the driveway. Here’s what I learned.

I eventually got it into 4wd Low by shifting gears (automatic transmission). In 4wd Low it crawled up the driveway and I could park it somewhere flat.

I used a terrific blog to diagnose the problem: https://axleaddict.com/auto-repair/How-Do-You-Know-if-a-Throttle-Position-Sensor-is-Bad

Turns out there are many possible problems and solutions BUT THE PROBLEM IS PROBABLY ELECTRICAL.

In my case, I found that Sensor 2 was not getting power (no 5 volts like Sensor 1), so I started looking around. The TAC (Throttle Actuator Control? Maybe some other name?) is on the firewall up high on the drivers side. There’s two plugs with a bunch of wires going into it.

And there I found that a rat had chewed through a green wire and a blue wire with a stripe.

I reconnected them with a butt connector and instant fix.

I don’t like rats.

Good luck.
