After upgrading the stereo system in our 97 Civic HX, the remote door
lock control will not work. There was two parts to the original stereo
system. One was up by the heater controls and the CD player was down by
the cup holder. I have checked the fuses, under the dash, but they are
all okay. Any reason why this would happen? Any suggestions on what to
check? Everything worked before the install so I'm a little lost right now.
