code alarm door locks problem

Hello everyone.

I have a code alarm system, ca425 or ca640 cause I had to bought them together to fulfill the kit for the remote start stuff.

Well, I installed this alarm in my own car 5 months ago, it just worked perfectly but suddenly the door locks stopped working.

I bought some "supposed" special door locks, these door locks have 5 wires so every time i opened the doors manually the others door locks worked equally. these door locks come with a fuse and a built in relay pre connected, you just need to plug the harness, then 12v, gnd and the wires from the module..... then from that relay goes the 5 wires to every door lock.

I reviewed the fuse and that built in relay. no problem with them.

I took back these door locks, i connected them to another source and these didn't work.

SO i installed aftermarket actuators (obviously using the base of these 5 wires door locks in order to mount it properly), then i tried the connections indicated in the manual

which are:

relay 1:

86 and 87 to 12V

relay 2:

85 and 87 to 12V

that's what the manual indicates, and it dind't work either.....

so i tried the conventional conections as shown in this website where the only difference is the connections between the 12V constant and the wire from the module.

I noticed that one wire from the modules rests at positive voltage and the other wire rests at GND. now i am not sure i this is normal...

any suggestion?...

please let me know...

87A connected to ground. I've tried that connection you pasted.

could it be possible that the outputs of the door locks are damaged?
