1998 F 150: The panic horn sounds off on it's own when the truck is not running. When it goes off, I can turn it off with the remote keychain, and it will not go off again until after I drive the truck. Fuses seem o.k. Any help would be appreciated. Thanks!

 

Alarms are weird some time my sis's alarm is weird to. We went to the store car was running rine got out of the store went to start it wouldnt start i reset the alarm and it started. Also if its to sensitive it will go off from tremros (that we cant feel).

 

is it a factory panic button?..no aftermarket crap?

 

It's factory button. The horn blares sometimes when I open the driver door.

 

Yeah, its really weired.,we have the same problem..[:@]
