Hey guys, in desperate need of someone wiser/more skilled than me. Will provide a $100 gift card to an online store of your choice if you can provide a successful solution:

Problem: Lost power to my backup camera (Intellilink displays guide lines still, just no image and a "service rear vision" error message) and also lost power to the rear heated seat/HVAC controls (front controls and actual rear HVAC function still fine).

How it happened: Yesterday I attempted to hardwire my Passport Radar detector to my windshield mounted wiring, following the instructions found on this forum that many of us have already read. I've done this without flaw on both my past Tahoe and Avalanche, using my homemade "Invisicord" that has worked flawlessly for the last 6 years, and the Pin 2/Violet-Green and Pin 5/Black wires.

Long story short, it's tight in there, and my needle connector slipped and well, they touched. Small spark, and yes, like an idiot, I had power on as I was looking to confirm the connection (and because I was cocky).

Now I have a $65k truck that I've owned for less than a week with owner-induced problems, even if relatively minor. I'm beating myself up enough over here, so please keep the chastising to yourself. I would be incredibly grateful of a specific solution, and like I said, I'll send you a gift card if you can share specifically a solution that ends up working.

I've gone through all four fuse panels looking for an obvious associated fuse, but considering that multiple components went out, it must be something more general.

Thank you in advance.

Have you checked EVERY fuse, with either a meter or test light? Sometimes visually it will look good, but it will be blown. Check them ALL first. If that fails, get the radar detector out, bring it to the dealer and tell them it stopped working. F it. Its under warranty.

x2 on that exact post.

I would check EVERY fuse. Check them with a meter or test light - dont pull them all out!! I don't know but I assume we have an inside and an under hood fuse box. Maybe more than 1 inside. Check and manual and check them all.

If you still cant find it, I can look through what all of the wires that are inside the mirror housing are associated with and possibly find you a solution.

Check Every Fuse

There are 4 fuse blocks
#1 Under Hood driver's side
#2 End of dash on driver's side
#3 End of dash on passenger's side
#4 Rear fuse panel on driver's side just inside the rear cargo area
The best way to test fuses is "in place" with a test light.
Time consuming but best way.

ALL fuses are identified as to function and location in the Owner's manual, Section 10-33 in Denali manual.
Hope this helps.

It's definitely a blown fuse...just a matter of finding which one it is.

fuse

I think your best chance of finding your fuse would be to have someone else with a working camera start pulling fuses in their fuse panels one at a time to see which one kills their camera. I recently found that there are fuses called Retained Accessory Power fuses that control multiple things for the radio. Mine was in the Right fuse panel.

I routed my radar detector wires into the center console and spliced into the cigarette lighter wires.

Solved!

Fiatdale, thank you for your help! (check your forum inbox).

I had originally pulled out the owners manual fuse listings for all four blocks, pulled the obvious ones and everything looked okay.

What I have learned here is yes, just because a fuse looks okay, doesn't necessarily mean its good. I bought a $5 tester and checked every fuse and eventually found the #36 Fuse from the Drivers Side block blown. Visually looked fine, but blown on the tester. Replaced it and all lost functions were restored!

In other news, can't tell you how much I love my new truck. Thanks to all for your input.
