Proud owner of 2 Grand Cherokees. My 98 has issues with the electrical system they are all interior . First , at 15 mph the power locks do not automatically lock as they do on my 02 GC the owners manual says it should, interior lighting stay on all the time( pulled the fuse), rear window pop , power door locks and remote entry only function with the ignition switch turned on. My rear window wiper only clicks when switch is activated. I picked up a bcm at the salvage yard but haven't installed it yet. Is there anyone who went through this or can give technicial direction ?
