I recently installed a remote start and hooked up my door locks/unlocks with 5 wire relays. The unlock worked great, tested it while I was working on it, but after I hooked up the lock relay nothing works. I tested power at the actuator and it's receiving power from the alarm/relay when I lock/unlock from the remote. Are the actuator lock/unlock wires supposed to show ground? If I remember the wires would be grounded and when the unlock/lock is activated they show positive. I get no ground on the lock/unlock wires. I'm guessing my actuators blew out. Any help would be great.

 

First thing to do is check your wiring. Are your relays wired correctly? Do your locks work when using the factory keyless or the door switch? If not, then you have something wired wrong. Are you using the correct wires in the car? Are you accessing the wires at the keyless module behind the start button? Just somethings to think about. Worst case, take the relays out, put back to stock and see if the motors still work.

P.S. Check your lock fuse. If it's blown, that's a sure sign something is hooked up wrong. Good luck

 

are you using a 451m to drive your actuators?
