Hey guys this is my first time here and any help is really appreciated.
I have a 1993 full size chevy blazer and it had an alarm on it when i bought it. On the remote it says United States Auto Security i've never heard of them and i was told that all it was pretty much good for was the keyless entry(told that by a stereo store when i wanted to try and add remote start to it) but the problem is that when i press the button to arm and disarm the alarm it doesnt lock or unlock the doors anymore the alarm still arms and disarms though. Could there possibly be a blown fuse or something along those lines or is it totally shot.
I also just took it to a shop and they rebuilt the steering colum for me and i know that the alarm brain box is right under the colum. It worked for about a week after i got it back from the shop could they have messed something up? Any ideas or suggestions would be great thanks.
