No air from vents, no horn, DC outlet not working, no lights when remotely locking

What is your question?

Here goes... I seem to be suddenly having a wide range of problems with my 2011 Nissan Sentra. This past winter I changed the motor because the timing change went (I caused it by being a crappy car owner) but since then everything else seems to be going. The heat had stopped in it before I took it in. It made a bad rattling noise for a while then just died but would still push out warm/cold air when I was driving fast enough. I've now replaced the blower motor but I still have nothing blowing. Strangely enough it also blows out NO cold air even when the ac is on and I'm on the highway. Since then my horn has also gone, my lights no longer flash when I unlock it and now my cigarette lighter keeps blowing the phone chargers I put in it. Is there any way this could all be related? I'm lost and don't know how much money to keep sinking into it

What makes this problem better or worse?

Nothing
