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?

Airbag light always on.

I have read all I can on an airbag warning light that is always on in my 05 2500 sierra. It throws the code B0026. From what I have read there is a 4 way connector (yellow) on the drivers side under the kick panel. I find a 2 way connector but no 4. I have checked the impact sensor under the radiator housing and it does show some resistance so I am assuming that is ok. I can't find any wiring under the passenger seat to check its connection. If you can help I would thank you ahead of time.

    B0026 is the drivers frontal deployment loop open. That's the drivers airbag circuit in the steering column has gone open. Common failures would include the clock spring, beyond that you really need a qualified technician to service this system since there is so much liability resting on its operating correctly should it ever be needed.
