I installed the 2 relays as described for the 3-wire setup on a positive door lock system required for my 1990 Cutlas ciera. Problem is when I attach the last connection which is the 12+ power all 4 door locks will lock and stay locked but keep pushing pressure in the lock position making a humming and vibrating noise until it sounds like the battery is draining, the vibrating sound will slow down and start to make a gurgling sound. When I take the power off, the door latches will stop and release pressure and stay in the normal locked position plus the unlock won't function at all, what could be my problem oh and btw when the relays are not connected the door locks work fine from the door switches.
have the same problem?
