here it is straight to the point.....

On my 96 t/a the fans don't kick on when they should when the temp reaches around 180-200 to keep it cool at 180. But when i turn the max A/C on or just the plain A/C the fans kick on and keep it cool. So everytime i am stopped i have to turn the A/C on so it will not heat up. Of course when im driving it stays the right temperature but they just don't want to kick on when i am at a stop. Anyone know what the problem could be or anything???
Input is appreciated.

Do you know that the stock fans don't come on until 226°? You may be perceiving a problem that is not there.

 

if anyone knows....it would be shoebox!! one fan turns on when you turn the a/c on(or defrost for that matter). not exactly sure the reason but I would speculate it is so that air is flowing over the condenser(radiator type thing in front of the actuall radiator) to cool it. at the 226^ that shoebox mentione that is when the other fan turns on. if you have the a/c turned off no fans are on til 226^ then both turn on.

you can program them to turn on sooner or install a switch to turn them on. there is more than one how to page out there about installing switches for the fans. I did it kinda getto and jsut took some insulation off the wires to turn the fans on and have a alligator clip that I clip on there to tun them on. bad thing is I have to get under the hood to do it....jsut been to lazy to run the wires inside and connect to a switch.

 

I was going to post the same problem or not.

If the fans come on at 226*, when do they turn off?

I am planning on installing a manual fan switch to help with traffic heating. I have a convertible and rarely have the top up so turning on the A/C is futile. Actually I have turned on the A/C to cool the engine down but it does not do a killer job plus additional drag is added from the A/C unit. The manual switch should do the job in Sacramento's 3-digit temps and slow freeway (traffic) speeds.

If I purchase a 160* thermostat will that help? Would I need to make any other changes other than installing the thermostat?

 

This will tell you what you need to know about the fan system. Donny O, both fans always run in a 3 relay system.
tomatocity, the fans switch will help you, as well as the 160° thermostat. There is nothing else you really have to do.
