Please forgive how this question may sound. I love my car (89 Formula 350) but i am in no way a do-it-yourself fix-it guy. After an extended stay in my garage this past winter my car awoke to three problems. The power locks aren't working, the horn isn't working and my antenna no longer goes up. Could these be related by any chance? Any thoughts as to what could have happened or what needs to be replaces.

Any and all advice is welcome and appreciated. Thanks.

 

Looking at wiring diagrams, the antenna and horn both go through the ACC fuse... Although the power locks do not appear to, it could be a common factor.

I'd check your fuses first, then relays and switches, and leave the wiring for last if all those check out.

Power locks are off the Courtesy (CTSY) fuse and the Power Accessory fuse (PWR ACC). Have you tried the switches on both doors?

If your radio turns on, then it's not the Radio fuse, but the antenna relay also takes juice from the main ACC fuse...If they're both good, your radio might not be passing the signal to raise it, the relay could have went out, or the antenna motor or wires could have gone bad. I'm not sure of the location of the relay.

The horn is fused (main ACC) and has a relay. I'm not sure of the location on the relay.

 

Check your fuse box. I had a similar issue a while back. Changed a fuse and poof problem gone

 

Thank you! i'll check those out today.
