2004 Mustang V6, 3.9. Stock radio no power, (Switched/ignition) only cd player and menu on the radio work. I also have no wipers blade power. It's also a switched unit. I wonder if the share the same cable swiched power cable. All fuses check out OK by the way. I used a circuit tester and pulled the cable tape back on the pink/black switched power cable and have no power getting to the radio with the key turned. The good news is that the under dash fuse box works as it should. So it seems I have power from the battery to the driver inside fuse box. What do you recommend I do to find the open circuit?
JA: There are so many things that can cause battery issues. Some simple, some complicated. The mechanics have tons of experience in that area. Will the car start?
Customer: Yes, all works except the windshield wipers and the stock radio head.
JA: Glad to hear that.
Customer: I am Sergio in FL by the way. Nice to meet you. I put the car back together this morning but I am home now and just disconnected the negative from the battery and am pulling the dash apart.
JA: How old is the battery?
Customer: About 6 months. Funny story I thought I had an AC problem back 6 months ago. Turned out it was a battery/Alternator
issue. I did not have enough volts to engage the magnetic clutch
JA: Anything else I can tell the Ford Mechanic before I connect you two?
Customer: Battery is fine on volts around 12. And running hits around 14 volts
JA: Got it. Let's get this figured out. I'm sending you to a secure page on JustAnswer so you can place the $5 fully refundable deposit now. While you're filling out that form, I'll tell the Ford Mechanic about your situation and connect you two. You'll be on the road in no time.
