Working Around Ford F-550 Super Duty Mirror Problems
Your electric Ford F-550 Super Duty mirror is more than just an ordinary mirror. Its heavy-duty construction can withstand damaging outside elements, and it is electrically powered for easier adjustment. But no matter how tough and advanced your Ford's mirror is, it will eventually malfunction and probably even jeopardize your safety on the road. If your electric mirror is in bad shape, you might as well take some time off to check on it right away before it completely breaks down. Below are the possible causes of malfunctioning Ford F-550 Super Duty electric mirrors:
Blown mirror fuse and loose electrical connectors
The electric mirror on your Ford F-550 Super Duty truck relies on a properly working fuse and tightly attached electrical connectors to adjust its position according to your desired angle easily. If the mirror's not moving each time you press its power switch, then the problem may lie in the fuse and connectors. You need to remove the box cover from your Ford's fuse block in order to have a good look at the circuit's main fuse. If it's blown, there's no other solution to this problem but to replace it. Blown fuses won't work no matter how much you try to repair them, so save yourself the trouble and get a new fuse. To check on loose electrical connectors, remove the mirror from its bracket and lightly tug on the connector. If the connector seems to come off or detach itself from the mirror, you simply have to reconnect the mirror and secure any loose connector properly.
Zero voltage and faulty wiring
Voltage and wiring problems may also prevent the mirror from being adjusted. You need the help of a test light to properly diagnose this problem. The test light will be able to check and monitor incoming voltage at the wires connected to the mirror's motor. Zero voltage means you have faulty wires. Check on the wires to see if there's a break or short in them and replace these faulty wires right away. If voltage is not a problem, then you need to replace the entire mirror assembly.
