You're turning the defroster grid on, right?

Yeah bottom button to the right of the power button on the HVAC panel.
Old mirror plug on top, new one on the bottom. Same number of wires in same positions. Colors are different, but I believe the functions are the same regardless. I test plugged in the old mirror and that won't heat up either. I opened that mirror up on the bench and did some tracing with a ohm meter. The black wires on BOTH plugs are definitely for the heated glass. I am afraid to go prodding around the door lock module with test meter probes.

My fuel economy on E85.
yeah I dunno wtf is going on here fuse is good, relay good, rear defrost button is lighting up. Still no power reaching the heated mirrors. I am wondering if the door lock control I replaced isn't programmed for it maybe?
Coming up on 345K.
I feel like fkn Clark Grizwold with the fkn Xmas lights only it’s heated mirrors.
check for continuity on the mirror wires

Purchased a power adapter to plug my dash cam into the rearview mirror. Pin 1 is ground (Black) and Pin 8 is power (Red/White). Works great, no more wires hanging off the mirror and blocking the radio.

I hope every one had a great Thanksgiving ! I have been away awhile.
Have a shock replacement question: 2007 GMC Yukon SLE 5.3 Flex fuel
I need to replace the original ( 77K miles ) rear shocks. The OEM ones are pictured as are the heavy duty ones.
I never tow anything, but will be towing a 20 foot cargo trailer next summer from Seattle to Ohio and am thinking maybe I want heavy duty shocks vs OEM standard
Everyone's thoughts ? thank you in advance

Welcome back!
In my opinion heavy duty shocks won’t offer significant benefit over the factory part for towing. The problem won’t be damping - it will be sag. For that you’ll need either adjustable air shocks or supplemental air bags.

What does it do exactly?
It converts 12VDC power to USB 2.0 power, which is 5VDC I believe.

Yea I have been sitting on mine undone for the past couple years.
Hardly ever is someone in the passenger seat of my ride.
it's just a hard wire adapter to supply power from the mirror harness instead of having to have cables hanging down to the cigarette port. I use a similar one for my radar detector and another one for my dash cam
Already did. They check out. The door switch is not sending power to those wires. So I don't know if it is a programming thing with that or the problem is between there and the defog switch. Need to look up some wiring diagrams and chase it down.
