Are you a current or recent car shopper who bought an EV and then installed solar – or who had solar already, making the decision to go electric easier?
Are you a recent EV buyer (past 3 months) as a result of manufacturer incentives and dealer discounts on these vehicles, including year-end deals? Were you convinced to buy an EV after finding a good end-of-year deal, or due to uncertainty around which EVs will no longer qualify for full/partial EV tax credits in 2024?

No response from climate controls, no interior lights, and no keyless entry.

Alright, I'm stumped. A few weeks ago, I removed my hvac controls to replace the bulbs with LED's, I made a simple mistake and ended up causing a short when I was all finished and got it all plugged back in (too much solder, bridged both contacts on one of the LED's), and that hvac unit went up in smoke, literally. I grabbed one out of a junkyard, replaced the old lights with LED's successfully this time, turn the car on, everything lights up and looks to be fine, but then I realize that none of the controls work, I mean literally nothing other than the lights. No response whatsoever no matter what I push, no rear window defogger, no indicator lights when I attempt to turn the fan on, nothing.

Then I realized my interior lights weren't working either, not when you push the button on the lights, turn them on from the switch on the dash, or open the doors, and my keyless entry also doesn't work, no response at all, changed the battery in the remote and nothing.

Checked all the relevant fuses, all of them were good. All my searching led me to believe I somehow fried part of the bcm when the short happened, so I got a brand new one, had it reprogrammed, and the problems still persist. I'm at a loss here, I have no idea what else to do. Any ideas?

    Using the GM Tech II, retrieve and list all codes from every module on the car. Also notate any modules that are listed that the vehicle was equipped with but are not communicating.
