Electrical problem
2000 Nissan Altima 6 cyl Front Wheel Drive Manual 80,000 miles
----------------------------------------------------------------
My Altima's alarm system began to go off at will, without reason. Even using the remote does not disengage the alarm. The doors lock, lights flash and horn honks without stopping. Only taking out the anti-theft relay switch AND the horn relay switch got it to stop. When I took out the anti-theft relay swtich only, the horn still kept going. It has stopped for spans of time, but then goes off again and will not respond to any of my attempts to disengage it. Do you know what might be causing this and whether I can fix it myself? I mostly need to be able to use my horn again.
Thanks!
