My problem got worse tonight.

I took the fan relay out. I started engine, disconnected the coolant temp sensor, and the fans came on, as they should.

I disconnected the relay, and the fans stopped.

When I reconnected the relay, the fans worked momentarily, ten stopped. Now they won't work at all.

Some probing with the tester found the following;

1. The connector for the relay is working properly - grey wire is hot, 2 others are ground, the green one goes to the fan.

2. The new problem - the plugs for each fan have ground at both terminals. If I'm not mistaken, I thought that one terminal should be hot at all times, and the other terminal is the ground which is controlled by the relay.

I've done lots of electrical over the years, this system & problem really have me stumped.
