We were swapping out the fluorescent high-bay light tubes in the shop for LED, so everything had to come out of the shop. After we finished that chore, we decided to exercise the vehicles a bit. As usual, I find new things that need fixing when we do that, and I've come to expect it. When we got to the Dakota, hopped in and started it up as usual. Sounded great, as usual.
After start up, the ABS light came on. I've dealt with that before, and already swapped out the rear speed sensor, which worked for about 2 years. It's come on again. I'll probably crawl under the truck and 'cycle' the plug to see if it's just corrosion there. If not, I guess I have to find another sensor.
What I wasn't expecting came next; the Air Bag light came on! I even tried turning the truck off, turning the passenger air bag off and restarting. Still no fun.
My wife was going to ride with me, so I hit the unlock button to unlock the passenger door. The locks just buzzed. They'll neither unlock, nor lock by switch. Ugh! Had to reach over and manually unlock the door.
Since the weather was nice, I figured I'd roll the windows down for some fresh air driving. No dice! Neither window switch works. Sooo, we'll turn the A/C on and use it. Nope! The HVAC won't work, either! Neither did the radio. WTF!?!
I've never seen this before. It seems like about half the electrical is working!! Lights, turn signals, brake lights, fog lamps, emergency flashers, even the mirror adjustors work, but it seems nothing else does.
I haven't plugged an OBDII reader into it yet, but wanted to check here to see if anyone has heard of such issues. This is a 3800 mile R/T, and nothing has been done to it in quite a while. I'm stumped.
Thanks for any ideas.
