I have a 2000 Silverado 1500 and lately the alarm keeps going off while parked in my driveway. I noticed that also while I am driving the power locks will unlock and the interior lights will turn on. I have to stop or put the truck in neutral to get the locks to lock again and to make the interior lights shut off. I have tried locking my truck manually and the alarm will still go off. It is definitely an intermintent problem. Any ideas what it might be?

 

Initially I'd think it was a problem with the clicker but it may be something wrong with the receiver or whatever you call the thing in the truck that picks up the clicker's signal.

 

short?
