Ground locations for turn signals and rear brakes

Ok i need to know where all the grounds are located for my turn signals and brakes i just changed my brake switch thinking that was the issue but apparently not.

i got no signals blinking in the dash or on the outside.

also i have no brakes coming on but the constant red is on

i have headlights and the constant red nothing else.

any input would be much appreciated

the turn signals might be the turn signal relay have you tried that?

I believe the grounds are behind the plastic paneling on the insides of the rear quarter panels.

left side grounds behind the spare tire mount and the right side runs up to the floor under the passenger seat, IIRC.

It depends on the year of your rig. My 92 and 93 both ground to a bolt behind the plastic trim behind the spare, then that ground splits off to both sides as well as the hatch.

With a test light or VOM, probe the internal socket bulb contacts, with the other end of the light or VOM grounded to a good body ground. Then you will know if it is a bad ground, or no current getting to the socket.
