Loss of power to side view mirrors and back-up camera

This has happened several times. I lose power to the side view mirror adjustment controls and my back-up camera. The solution seems to be replacing the 5a fuse under the steering column. This has happened several times over the last two years. Replacing the fuse seems to work, but Iíd like to know what the ultimate problem is that is causing the fuse to blow. Today it happened as I was adjusting the passenger side mirror while backing up into the driveway. Has this happened to anyone else? Any suggestions?

2020 Redhawk 31f.

The 5A fuse blows because the circuit(s) sees more than a 5 amp draw. Some may tell you to install a larger amp fuse, but I would refrain from that until it is determined that the wiring can handle that much more amperage, or if one of the two devices on that fuse (side mirror and rear camera) have a wire shorting out to ground.

Was the backup camera added during the build, or after the camper was built? I'd suspect that circuit first if so.

Never install a larger amp fuse to correct a load issue until all circuits on that fuse are checked for shorts and wiring gauge capability.

If factory installed and if back up camera, side cameras and power mirrors on same circuit may be the cause. Was it in reverse and adjusting mirrors at same time?

Yes, it’s the factory installed back-up camera and in dash radio. And also yes, I was adjusting while backing up

In that case, install a 7.5 A fuse. It will be fine with the wiring of both the camera and mirrors.

Or, refrain from adjusting both the camera and mirrors at the same time, and stick with the 5 A fuse.

Check under the hood. I had the same problem with my MH. I found a wire harness rubbing on the steering column shaft. Rubbed through the plastic cover and the insulation on one wire. This would intermittently blow the 5-amp fuse.

Thanks! Iíll check that out and switch out the fuse for a 7.5 as well and see how it goes.

Power mirrors and backup camera

Hi Twindad-I am a twin daddy 2! We own a 2019 Jayco Redhawk and the dealership has contiunued to replace the fuses to support the backup camera and power mirrors. I was wondering did you ever resolve your issue and how? Thanks in advance!

A known and documented problem (here in past threads) with the poor wiring that Jayco does with the mirrors and camera system. The wire is running right at or behind the emergency brake. When the brake is applied it can clip or even sever the line, blowing the fuse or shorting the wire so that it blows the fuse at times it touches metal. Start there.


The other issue is that the wiring for that system is one of the poorest examples of running electrical that I have ever seen in my life. I have been back there to replace bad wiring and to install a different head unit.

Thank you CAG! I’ve been trying to get the dealership and or Jayco to fix it but no luck. Looking at lemon law but do I want a replacement if this is a known issue? Is it on all models or just certain ones?

It took having a problem with the right mirror diagnosed by an American run shop and them tracing the electrical bundle from the head unit, through the switcher, to the line running from the mirrors, behind the emergency brake and finding a pinched line to track it down. Then I found several other threads where the Jayco Greyhawk owners had found that that line had been run behind the emergency brake, pinched and shorted out cameras before solving this issue.

Sorry, but Jayco's specialized techs, hired from the Amish community are actually illegals, who crossed the border from Mexico, after traveling many miles from Argentina to get jobs in RV plants so they can screw up our rigs before they even leave the shop.
