'91 Cooling Fan Circuit

[GatorIsaac]

The cooling fans on my '91 GTA have quit working. Fans operate when jumped and I have replaced the relay....still nothing. From where does the initial control signal come?

On my 85 , there is a sensor on front of engine near my altenator.
Coolant Temp Switch, but not the one for the guages thats on the side of block.

Bingo, Thanks!

I checked both sensors. Although the looked fine and appeared to be connected one must've been loose. The fan is working fine now.
