Hummer H2 For those who like a little more gleam to their Hummer, the H2 offers a similar rugged look as the H1, but as a lower cost, and with more added features, making it almost a massive luxury SUV.

Default Help!! I’m going insane!! H2 2005 Hummer

Hey y’all. I bought my hummer a couple months ago. Haven’t hardly even drive it. Decided to take it for a run up the gorge and bam! Everything started going haywire on the dash.

All these lights come on for no reason. Shuts the radio off. All the gauges drip to zero. The door locks quit working. Hit the T2 and all Come back up except the T2 and the ABS. Have brand new brakes all the way around too. Any advice?

I had a similar failure.
from my side I had two plugs that got wet and caused a short circuit. Take a look to the „electric problems@ thread.
