Blinker light on the passenger side of our 28 Foot FC works sometimes and not others.

The blinker light on the passenger side rear works sometimes and not others. Could it be a loose bulb, a dying bulbar what? How do you replace the bulbs?

[ROBERT CROSS]

I would start at the bulb and socket,(center post in the socket is +), most common for intermittent is a bad ground.
A test light is your friend. Connect to the power with the probe and ground the clip.

How do you assess the light bulbs on the FC. Looks to be sealed

[ROBERT CROSS]

On the later AS's it may be a sealed LED unit. I'm not sure how they are fastened.
On our Classic the lens is removable.

If its this style the assembly can be removed.The holes on the end of the housing should have the fasteners.I believe that the wire connector can be a concern because of the size of the wiring hole on the AS.

Some folks with a late model FC should have more info.

This is a good source.
Call for more info.

My blinker did the same on my 2019 FC. I cleaned the contacts at the TV plug with a small file and applied some electrical lube. Problem has not returned.

Water intrusion can cause intermittent failure.

I have found the most common reason for a light not working or intermittantly working is a bad connection at the TV plug. Look at the contacts, maybe bend a contact slightly to make a more reliable contact.
