I just replaced the vacuum solinoide but forgot to disconnect the battery first. Immediately I got some strange electrical issues. Any idea what this could be? I checked a slew of fuses but am wondering if I just need another new solinoide.

Try disconnecting the battery for 30 seconds or so and relearn the brains?

I did that. It has two batteries and I disconnected both for a few minutes. The heater blower will not work when the car is on, but comes on when the car is off, the right blinker stays on too.
