Been having an issue with my "right blinker" lately (face paced blink), did some looking around my guy and found my "drivers side" has some dry rot. Turned the lights on and manually moved wires and the light went on and off (drivers side).
Question: Can the drivers side trigger the passenger side to blink faster?
Also, it's not happening consistently.
My drivers side LED headlight seems to go out also, thought it was moisture related but now every time I go out to change it, is working (its 93 here in FL and I don't have a garage).

Also trying to locate the OEM part number for the piece that dry rotted (see pic) and hoping I can just splice on a new one easily?

Any feedback?
PS: I am not that mechanically knowledgeable but willing to try to fix myself first before I take it in.
TIA
