iroc-z dual fan problems
I just finished welding up my dual exhaust setup and i always dissconect the battery terminals when i weld on my car but when i took it for a drive yesterday and it never goes about 190 degF i have the prom programed to tunr the fan on at 170f but it never came on durning my drive. I have the secondary fan switched so i can turn it on any time, because it's not controled by the ecm. I tested all the relays and wires and the fans work. If i ground the green/white wire at the ecm the fan comes on, also my diagnostic computer says it's turned the fan on but still nothing. I switched the ecm the prom and i also dissconnected the a/c presure switch and it still wont come on. Does anyone have any suggestions? I don't mind running it off off the temp switch on the block but 230deg F is too high for my likeings and this problem is annoying me.

It seems like you’ve tested everything except the temp sensor to the ECM that causes the fan to come on.
Happy Racing!
If People Drove Any Slower They’d Be Going BackwardsFog lights are not driving lights. Keep em turned off slow pokes.
How bout those dorks too scared to drive without headlights on in the daytime!
