1989 Iroc that has an old after market alarm My headlights radio ( after market) door locks dome trunk release all aren't working. This happened before and after using the key fob a few times locking and unlocking they like magic came back on. Now no such luck. I checked the fuses and they are all fine. I unplugged the fuse for the alarm. Plugged it back in and the headlights will blink when you lock it with the key fob from the old alarm but still no headlights etc... (A ways back I had this issue and it was the cig lighter shorting it out i disconnected it and it worked fine until this) Any idea what could cause this ? Im thinking of starting by disconnecting the alarm. any ideas will be greatly appreciated. Thx
