Hi guys,
I have a viper 791xv alarm system installed in a 98 Intrepid. The problems started about 6 months after I installed it.
What happens is, the alarm will work perfectly fine for several days. Then I will go to arm/disarm it, or pop the trunk, whatever function, and it will not respond. If I keep trying the remote will display the out of range icon. Its as if it forgets its programming. At this point, if the alarm is armed, I have to open the door, set it off, and disarm it manually with the program button.
Then it will work fine again for a few days, then act up again.
I have had it to an alarm shop and they could not get it to act up.
I hate to trash an expensive alarm system, but I have my dash out of my car for other repair issues, and if I cant figure this out I am going to remove it completely and go with a different alarm.
Hope you guys can provide me with some suggestions as to what it might be. Thanks
