Title: 1986 K10 power lock actuator relay - Where is it ;>}
Post by: PBritty on September 12, 2017, 03:35:08 PM

Hello,

I have trouble shot everything on this;  new actuators work, power good from fuse box, switches good, so I think it is the relay.

Is this relay under the hood or to left of brake booster behind firewall or is it on the steering column as I know it is hard grounded via the box or "so I have heard."

Thanks for any help!!

The door locks ground through the relay mounting bolts.  IIRC, the relay attaches to the brake pedal support under the dash.

Did you verify the relay is bad? The relay is case grounded
