So i bought this 2000 V6 Mustang about a year ago. Went to replace the stock radio because it didn't work right. Well when i did the windshield wipers stopped working. After a few days it started working again. No issue for about 6 months. Now i go to install another radio(attempt #2) tonight. Haven't messed with it in months after the last attempt, and once again the wipers are no longer working. Im not that mechanically inclined. And was wondering if theres a ground or something thats connected close to the radio or something that im not aware of that may have come lose. Any help is much appreciated. i can't rain X my window forever and just hope they start working again. i checked all the fuses again after it started acting up again and it all seemed to be in working order so idk where to start.
