I installed an aftermarket alarm in my 95 C220. I hooked up the door lock/unlock switch in the vacuum (it had an old keyless entry) and hooked the door pins through the front/back passenger door.

Everything works fine except:

1. When the car is on and the front passenger door is opened, the system goes to valet mode. If I keep the door open for a few more seconds, it goes back to standard mode and so on with the cycle

2. The lock/unlock switch on the dash doesn't work if I start the car. If I disconnect the alarm, the switch works fine. If I open the right rear passenger door and start the car, the dash switch will work

3. If I arm and disarm the car rapidly, all my windows will roll up and down.

4. If I leave my sunroof cracked open and arm the car, it will close.

I installed the same alarm in my other car (Isuzu) and never experienced any of these problems. I even switched the alarm brain to my other car (process of elimination) but it worked fine.

Do I need to have the car BLESSED

Did I go wrong with my connections? The only wire that I am having doubts with is hooking up the alarm yellow wire (ACC) by the front passenger running board, where all the wires are. I found a small box with 2 fat red wires bolted to it.


Need help guys

I'm not an electrical tech but had installed an aftermarket keyless entry on my 95 E320 wagon. I was able to get the keyless entry to work but could not get it hooked in with my alarm. I gave up and hired someone to help me wire it to the alarm as well as added blinking lights with arm and disarm. Now works fine.

A couple of things I have noticed and the tech brought up. On my car, if you use the key switch to lock then hold it in the lock position, the windows and sunroof will close. The tech believes that the signal being sent from the aftermarket control unit is long enough that the factory alarm thinks you are holding the keyswitch to close the windows. Thus the sunroof will close.

Also, when I unlock with the keless entry, then lock and unlock again within 5-10 seconds, all of the windows will roll down halfway. No explanation but likely due to the longer signal being sent to the factory alarm again. Strangely it only happens when you unlock, lock, and lock within 5-10 seconds. Otherwise it works fine. Actually, sort of convenient on hot days to cool down the car.

Sorry, can't help you much more than with my own experiences.

So I am not alone afterall. Mine acts that way too. The windows rolling up and down is ok. What really bothers me is my alarm goes to valet mode when the front passenger door is opened while the car is still started. It sucks coz you have to change it back to standard mode everytime.

Also, when somebody wants to open the door, I can't unlock using the dash switch. Either I have to shot off the car or open the lock manually.
