Fixed my last remaining fan speed. Issue was that the connector for the fan speed resistors was not fully seated. Looks like thats going to be a theme. But hey, my reverse lights are working!
If anyone was curious, this is the result of upgrading to LEDs for my gauge lighting. This should give a fair representation as this is low light and not night. They are a nice upgrade, but I think they work best in tandem with regular bulbs as some like my hvac controls are too bright.
I have noticed a few odd things regarding the electicals. The car seems to struggle to run anything without the engine on. This may be a side effect of me running the battery down, but it is disconcerting nonetheless. Also, when I activate my high beams, the low beams shut off. This may also be because the car is off, but I believethey should all be on at once.
