It\they may not be required. One should come on with the ac on, have you tried that?

 

Does the car overheat?

fans set to come on ??

sorry to be a pain , just at the age you hate to break down on the road,

I would think 195 or so. Try swapping the fan relay with the horn relay, could be that relay is bad. Does your instrument cluster have a temp guage or just a light?

 

hi Kevin , it has a gauge, please explain to swap relays ,
i am new to new chevys, i am a old solid axle corvette man
these i can fix
many thanks, rocky

 

Under the hood is a fuse box. There should be relays and the lid to the fuse box will tell you what fuse/relay is for what. Remove the fan relay, and plug the horn relay in that socket. Also check the fan fuse.

 

Also check the fan fuse. The other thing depending on your skill level is to jumper the socket pins under the fan relay, that is a direct circuit from the fuse to the fan motor.

 

hi guys , still having problems sorting out my non working fans,
I removed the hook up on the sensor on the intake manifold,
both fans came on very strong.

I then checked fuses [ marked fan cont. 2&3, fan cont1 ]
and exchanged one for the other, no change still no fans.
also no breaks in the fuses, both appear good and not blown.

I then exchanged the fan cont. 1 with fan cont. 2 , no fans
and then test both relays in the crank relay position on the upper fuse box
all relays tested as much as my limited know how could go, I am lost
cam someone pleas assist me on how and what to check next ??
please post

happy holiday. many thanks, rocky
