While driving I noticed dash lights becoming a bit dimmer until they became very dim and shut off, car kept running for a couple miles yet before losing all power. Changed the battery, now starts and runs fine, but radio is dark and auto headlights don't turn on. They work manually though.

Hello,

It sounds like you had a voltage surge when the new battery was connected and popped a fuse. here is a guide to help you check with the fuse locations:

Is it possible its the alternator? And also, upon changing battery, all gauges are inactive as well as digital odometer, plus power windows and radio wont work unless key is in the acc position. When car is running many of the accessories are unavailable.

All the fuses were seemingly fine, upon recharging up the battery, all those earlier mentioned accessories suddenly worked again, multimeter reads around 12.7 on battery without engine running and jumps to 14.2 ish with it running so alternator seems to be doing its job, is ignition switch a possibility? I thought I remember hearing something about a recall on the intrigue on the ignition switch
