1999 acura RL gremlins
Hey ht, my girlfriend drives a 99 RL and has just told me for the last year when she is stopped and idling her coolant temp almost maxes out. So I went to take a look and neither coolant fan is turning on. After letting it cool down and starting it a few times both fans kicked on randomly. Now they won't come on again. Any ideas? Possibly a bad relay?

In the unplugged fan switch connector, measure voltage on the power wire and continuity to body ground on the ground wire. What do you find?
Also post the circuit diagram for the fans.

It says I have 14v on one side of the relay and 0 at the other three. This was at the Rad fan relay. At the rad fan main relay I have 14v on two of the pins and 0 at the rest

Got it, every diagram i could find was pointing to the sensor on the thermostat but i checked the rad and there is a control sensor in the bottom passenger side, jumped it and fans came on so i guess im replacing that sensor
