Brake lights and turn signals don't work on my 85 gmc
I have an issue with my brake and turn
signals the front left works but the front
right and rear don't, as for the brakes no
power going to brake switch. I changed
switch and flasher.checked under dash
connect ion get power through both ends
checked tail gets power through socket ,
but doesn't blink when turn signal on
,also checked harness for trailer hookup
and it flashes through the pigtail .so I'm
scratching my head. Any suggestions
tried to troubleshoot.
I really hesitate to say this, gearheadnard321, you strike me as somebody that knows what they are doing. You have done all the right things. But you don't mention bulbs.
I sized them up as much as possible and keep focus
