I have this exact relay in my car under left headlamp. I have been trying to figure out how to test the "command" wire (lg/db) wire with an ordinary multimeter.? since it is a pulsed ground could i test it with an ohmmeter?

I have been a certified tech for 45 years and? I remember the chrysler has a solid state relay (as you have shown) but another model has the ss relay under and behinf the left front headlamp. It is very hard to get at. I have found that it is a lot faster to remove the right, sorry front headlamp assy. and with a 2" holesaw, drill a hole to the rear of the fiberglass rafiator support. Then you can reach the screws that secure the ss relay.

All because they used a solid state relay instead of a more rugged mechanical one. The only reason they did that was so that they could control the fans with Pulse Width Modulation rather than a? large ceramic dropping resistor. This is done by rapidly switching the relay on and off to control speed.
