on my 91 gta, i have 2 fans located behind the radiator- only the one on the right side (drivers side) works- while the other stays off; i tried putting the heat on to try to see if it comes on but still no luck; also thought that when the engine overheats that it would go on, and that isn't it either-so i'm guessing 1 of 2 things, 1 its not functionable, or 2 that it is there incase the other breaks, who knows!!!!!
any ideas or comments are appreciated!

 

It should come on when the AC is used.

 

Correct, it goes on when the A/C is used or when the temp reaches 220.........

 

right, well i put the ac on and only the drivers side one still works, i guess its broken-
