it all started when i was switching the taillights. i installed it all in and noticed that the taillights and cluster wouldnt come on when i turned them on, but if i stepped on the brake light, the taillights would light up. so i check the fuses and the fuse was blown. so i replaced it. and the lights and cluster work now. but heres the problem, now i can turn on and off my alarm but my door locks wont lock and unlock. usually when i turn on and off the alarm, my tailights and cluster flash but they dont work either, i dont understand what can be causing this, its confusing, but if you guys can help me with anything i would appreciate it

 

It probabaly has to do with your alarm maybe? I don't know much about alarms but you must've shorted out something. Next time I'd disconnect the negative terminal before working on any electrical component.
