I GOT A PROBLEM. I HAVE A 95 Z28 HAD THE MOTOR REBUILT. FANS HAVE BEEN WORKING. THEN TODAY THEY DIDN'T COME ON. AS LONG AS THE CAR IS GOING I HAVE NO PROBLEMS. I HAVE CHECKED EVERY FUSE ALL ARE GOOD UNDER THE HOOD AND IN THE CAR. RAN SOME HOT WIRES TO THE FANS THEY WORK. HAVE NO CLUE, HATE TO HAVE TO TAKE IT IN FOR THIS. ANYONE HAD THIS PROBLEM. ANY HELP WOULD DEFF. BE APP. THANKS FOR YOUR TIME

 

Take your cap lock off.

Do the fans come on with the A/C on?

 

check your relays....

 

Shortly after I bought my car I had the same problem... Like you, I checked the fans and as suggested above, the relays.. changed the sensor that triggered the relay and found nothing... In period I was trying to study this problem, I began to drag down to the track and I found that there was a solid tenth to be gained when running the car at 160 as oppossed to the 190-200 it ran normally...

I wired up a switch and I've never looked back; and have since added the EWP... the combo lets me HOT LAP my car and rarely see temps approach even 180. If I cut the engine off, I can cool her from 180 to 160 in less than a minute; which is handy.

Of course I live in SW Florida...
