my mustang and viper worked fine until one day the driver's side door would not unlock, the power locks stopped working, and when the alarm is triggered the horn does not sound(the lights flash and the starter kill works, and I can disarm it with the remote). I forced the door to unlock using the key and a wrench. I removed the actuator which was seized in the "locked" position. I can't however figure out why the auto doorlocks don't work and why the horn won't sound.

Please Help!!!

Thanks,

If the locks has seized on your system, the locking output of the Viper may have been damaged or blown. Have you checked the output on the Viper to ensure that you are still getting some current when you press the alarm FOB ?
