P0650, P1626, U1000 - No Speedo, Tach, Radio and more

[MikadoWu]

Hello All,

I am kind of lost of where to even start on my 2001 Trans Am Ws6 Vert...... Car ran great last night. Heading to work this morning and the Dash light where not working. I figure its a fuse, no big deal. Turned the radio on and drove to work. At work I popped the trunk pulled out my scuba tanks and pressed on.

When I was leaving work, the Trunk Switch on Key Fob would not work, I used the key dropped gear in and got into the car. This time, no gauges and worse no Radio, no speedo or Tac. Found the Power Accessories fuse was blown. I replaced it and the oil, tmp gauges started working, no Gas Gauge. Drove the 45 miles home with no engine issue. Put the scanner on it and got these 3 codes.

Anyone have an idea? Ignition switch, maybe? or Computer? I have a 2001 Firebird V6, could I swap the ECM?

Another post lists - 650-the mil light needs to be fixed. Whats the Mil Light?

How's your WS6 now? My buddy got this WS6 project throwing the same P1626 code. We'll take a closer look including the car history soon after we finished installing the brake pads and dick cepek tires on the truck this week. Appreciate any update.
