door lock malfunction viper 5900 sst

Looking for the electrical gurus here- Vehicle- 2000 S10 Pickup 4.3 L 4wd Zr2 Package The problem is that the door locks are always locked and when you push the unlock button, they unlock and lock right away. I did some testing and figured out it has to do with the wiring associated to my Viper 5900 SST security/remote start system. I diagnosed this brain box, and i think the brain box is alright, however when no signal is going to the blue (lock) wire, the door lock actuators are always trying to lock.... If you unplug or put a SMALL like 10 milliamp signal to it, they do not stay trying to lock and you can unlock the doors and it seems to function normally. I am thinking maybe a relay in the wiring is messed up, hence the reason why the door lock signal is sticking.... Any idea where a relay for this may be placed?

Has the alarm been in the vehicle for a while?   Was it working properly when initially installed? You need to disconnect it until you get the problem resolved. The door actuators are not constant duty devices.

It was installed on 2/6/07. Worked good back then and up until about a week and a half ago.... Any idea if my car would have a relay inline from the door lock wire(alarm) to the main door lock wire? I will do somemore searching....

sounds like a relay is stuck on

Are you saying that the locks work properly when the 2 wire(green and blue) connector is plugged in to the Viper, and then malfunction when that connector is unplugged? Or vice versa? If the malfunction stops when the connector is unplugged from the alarm, I'd suspect a short or burned out component inside the Viper brain. If the malfunction stops when the connector is plugged in, the case would possibly be a lock switch which is shorted closed, sticking door lock relay, or the lock circuit somehow otherwise shorting to 12V+. It's possible that the installer used a relay between the Viper and the car, but this is unlikely since that particular Viper unit is capable of controlling the locks on your truck directly.
