Seems you'd go to the Red/Blue and the Red/Yellow with the meter and make sure batt voltage shows up when you go UP/Down respectively.

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).

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.
