Cooling Fans Not Turning On

Just picked up a 96 3.5 Concorde not running that needed a timing belt. After I got it running, it would overheat when parked at idle with the fans not turning on. I pulled the fans and tested them...they work. Pulled the fan relay and jumpered the battery terminal to the output...the fans came on. Relay is good since I swapped it out with the AC relay. So why is the fan relay not pulling in?

Could the coolant temperature sensor be bad? Also the fans do not turn on when the AC is on. I'm stumped!

What a surprise. It was the coolant temp sensor (the one mounted on the thermostat housing). All I did was disconnect it and plug it back in and now the fans are kicking in just like normal.

Why can't all repairs be that simple?


Cheers,

Joe
