They still won't come on....even if i stick the a/c on. Both fan motors are good, i changed all the sensors too. So now im looking at changing the relay. I grounded the fan switch plug out and the relay clicked but w/e...it's my last ditch effort.

Which one is the fan relay of these? (if any)

 

If you grounded the wire on the relay and the fans turns on then that means the ECM isn't sending a signal for the fan to turn on since that proves the relay works and you already said the motors work. Maybe a bad Coolant Temp Sensor?

 

The fan relay is by the battery... not on the firewall

 

I just replaced the coolant temp sensor

I grounded out the fan switch wire and it clicked from one of those relays on the firewall...

fans didnt come on though when i grounded it out..

 

which kit did you buy?

 

on my 89 Firebird I followed the wire dirrectly from the fan and found that it plugged into the driver side firewall. Can you post a pic of yours if its different, I'm interested.

quick search revealed

Oops, maybe I'm just being confused.. Fuel pump relay is by the battery. Check this link out. https://www.thirdgen.org/techbb2/sho...hreadid=233309

 

The relays that you showed the pic of, on the firewall, are of the fuel pump relay and 2 fan relays. The fuel pump relay is a 5 pin and the fans are 4 pin I believe. All use the same relay per GM parts dept. I just replaced the 2 fan relays. The previous owner did a hack job on the fans and I am trying to get them back to factory specs. My fans are not running with the A/C or anything for that matter. Just got the car running today (bought it nonrunning condition). I rewired most, but I am taking the multimeter to it tomorrow and hopefully pin down the culprit. Any ideas or suggestions guys, let me know.

Thanks,
Chris

There is a fuel pump fuse by the battery (1992 Z28 305 and my buddies 92 L98 Z28 are the same)
