Blower will not come on when furnace comes up to temp but can turn blower on with switch in fan setting.

I added lights and outlets to my basement and all of the outlets work fine. Before I started the switch on the wall controlled one light and all of the others had pull strings. I've tried everything but the switch will not turn off the remaining three lights. What did I do wrong... how do I fix it?...

NEC code when is it OK to have the neutral connected to a switch

I have a york furnace P2MD12H06401A after 1 hour it shuts down and gives a 2 flash error for a stuck pressure switch. The switch is new can it be wired wrong? The old one had 2 white wires piggy back and 1 blue wire. The new switch has 3 separate terminals

I have replaced the park/neutral safety switch on my 99 durango after it came up with the code for it being the reason my check engine light is on. I tested the three wires leading into the switch itself but the only one without power is the black and white one. The only thing I can speculate is...
