A friend of mine installed a BlackWidow 3200 car alarm in my car. Everything woked fined for about 2 months. After that whenever the car is disalarm the doors don't unlock w/c are supposed to. I checked the connections with help of both my car(2000 civic si) and the alarm's wiring diagram. I found out that some wires were misconnected. So I fixed it following the negative polarity diagram for door locks. Again, it worked for about another 2 weeks and stop.
The door locks when the car is alarmed or started or using the power lock switch. It wont unlock when disalarm or shut off or even using the power lock switch. I don't know what's going on , I checked every connections and everythings seems okay. I was wondering maybe there's a fuse busted(haven't checked) or I'm missing something. Needs everyones expert opinions or advice.
