Default Radiator/Cooling Fan Issues 940 Regina Non-turbo

Ok, so heres another issue that was touched up on when I bought the car and started using this forum. I went ahead and finally did the diagnostic test mode 3 which test all of my components(injectors, iac, coolant fan, fuel pump, etc.) Everything came on and worked like it was supposed to except for the fan. The fan doesn't hint at turning on, I didn't hear the relay click or anything. I tested the relay and everything checked out fine there, the fan only turns on high for a few seconds during stop and go traffic. While it isn't a big problem because the car doesn't run hot at all, it just got me curious. Also as far as I can remember the fan doesn't turn on when I turn the a/c on at any time either. What are some other things I can try, and are there any other ground points or anything I should check?

Edit: Also if the fan just happens to be running and I turn the car and ignition all the way off the ran continues to run for a few seconds, I was under the impression that when I turn the ignition off the fan should also turn off.

see what I said about the fan circuit in the other thread.... regina does NOT control the fan unlike LH2.4, so there's no DTM3 fan test. the fan will run on high after shutdown if the radiator is hot, due to the temperature switch on the upper right side of the radiator. the fan running on low is dependent on A/C system pressure only.

Ok, I replied to that one pierce, I made this thread just because I've always been told that its better to make a new thread when you have another issue haha, I didn't expect for anyone to see that other one though.
