i had a 1997 cl, that i recently crashed into a tree, so yesterday i bought a 1998 CL, but there seems to be a problem with it. It still has the factory alarm, and when it sits in the driveway the alarm sounds every 15 minutes or so... wondering if anyone else has had this problem, or could tell me how to fix it? The battery was just replaced... so i didn't know if there is some type of reset for the alarm...
Thanks for the help
