I had the same problem and it was a bad temp sensor. Instead of replacing the sensor, I simply hot wire the cooling fan using a toggle switch. Now, I just turn the toggle switch when needed. Good Luck.

replacedtemp sensor fan come on now but it seems they have a low output. I thought that before when they came on they where really blowing hard,any thoughts?

they are variable speed, they change speed according to engine temp. Get it real hot and they crank.

Check the wires running into the 3 relays on the center of the firewall. On my son's 95 it was the dark green wire (pcm to relay)that fell out when I tugged on it.
