Open door and horn blows
Although I've never experienced this problem before, in reading various Jeep related sites, it seems to be somewhat common.
Ref. 2005 Jeep Grand Cherokee 4.7l V-8
A couple days ago, I noticed that my clock had been reset to 12:00. The battery had not been disconnected and the vehicle had been sitting idle for a few days. Battery was fully charged.
Just yesterday, when I opened the driver's door (door had not been locked), the horn started blowing, then changed tone, and finally stopped after a minute or so. It now does this nearly every time I open the door.
Also, at one point when I switched on the spray windshield (wipers), the horn again started blowing with the same scenario.
I understand that a defective clockspring may be the culprit.
Thanks in advance.
