My 500SEL is equipped with a Derringer 2 alarm system that also locks/unlocks the doors. There is a red clifford LED on the dash.

When I arm the system with the remote the doors lock, parking lights flash, and the LED blinks. There is no chirping sound and I cannot get the alarm to trip. I can unlock and open the doors and drive away with the LED still blinking.

There is some type of switch in the glove box that supposedly has something to do with the alarm but I'm not sure what.

Does anyone no what could be disconnected that would cause this?
