left turn dont work with lights on

[Daniel77]

I have a 98 ford ranger sport .If you turn the lights on the left turn signal
wont work but the blinker marker light is on on the dash. If you turn the lights off .The left turn signal works . But the radio lights flicker with the turn signal . Any help out there ? Ive checked the bulbs & the fuses . Their ok . Ive got
to try to fix this before mon .

check for bad/broken ground wires on the left side headligt and signal light harnesses.

left turn signal not working

Found my problem . I put a trailer wire harness from u-haul on my ranger .
I just took this wire harness off . Plugged the wires back together and
everything is working perfect now .

fixed turn signal

I fixed my turn signal . The trailer hook up I bought from u-haul shorted out or something . I unhooked it and plugged wires back together and ta-da it
now works fine . Water may have gotten in to it and corroded it . I ve just took it out for now . Thanks guys
