I have a 86 jeep comanche. I have been reading the forum posted . I'm having issues with no dash lights taillights and dome lights . I continuously blowing 1 fuse and that would be the parking LPS . A coulpe weeks ago they came on and then went off. I have replaced the switch and relocated the ground. But still nothing. I got the buzzer back but only until i turn lights on. Any help would be appreciated
