Location shown in the attached jpg. out of the 87 FSM.
Second jpg just shows the left side retract relay, the right side retract relay is in the same area on the other side of the car. Behind the headlight assy and the afm/air filter will be in the way.

The problem does not migrate. It stays with the drivers side. I replaced the relay with a new unit.

If you have voltage there then check the gnd point. Problem is the left and right side relays share the same power wire and the same gnd wires with no connector inbetween the source of power/gnd. So I'd have said like I just did......swap relays and see if the problem travels.
You did not mention what wire is open in your earlier post. Seems a person could pull both relays out and ohm out b/t the two relays to prove there's no problem. But I'm more than less not a ohm out person given there's so manyways a ringout can mislead someone (simple light bulb filiment in the circuit over looked etc).

The relays are in good working order. The issue is prior to the relays.

I believe more or less in checking the voltage where it should be and checking the gnd points.
I've had one of these relays fail and it was internal corrosion. Pulled/cut the relay cover off and sanded the contacts and it worked..........for a couple of weeks........then bought another used one from the wrecking yard.

The relay I replaced was corroded. The unit I replaced it with is brand new (from the dealership).
