Says it overheats in traffic, highway driving its fine. Started it up tonight, let it idle in park with a/c on. Gets to to 210, climbs pretty quick (less than 5 minutes) to just under 260, which is when I turned it off. Letting it run I kept checking the cooling fan, fan never came on. So, I guess thats the problem, anybody have any ideas why its not?
I tried to find a fuse for it, but its a weird looking thing, doesn't look like a normal fuse or relay. Its a 40 amp, and there are other 40 amps under there, so I am going to swap one of em and see what happens once engine cools down.
Swapped the blower motor fuse (although it doesn't look like a fuse) for the 4.0 cooling fan fuse. With cooling fan fuse in blower motor fuse, blower motor still worked. Checked connection, its plugged in, appears to be no signs of wire damage from what I can tell. Check engine light is on now.
I guess the best bet would be to get a test light on the connector and see if the fan is getting the supplied power and ground.
wow this is fun hehe seeing all the different things people say and do.

put a test light on the connector. looks like a constant ground at the connector, and the fan is supplied a power. with a/c on, let it run up above 210,but below 260, never got one power signal from the wire. so i am guessing its the relay?
Or cut the hole like in my writeup and future changes take 5 minutes. I'm on my 4th fan relay. BTW, my "5-Star" dealer charged me 3 hours of labor to cut the hole beneath my headlamp. I discovered this when the relay they installed died.
BTW, testing the fan is a good first step - the connector to it is on the side of the shroud - it uses one of those red clips to keep it together. Polarity doesn't matter for testing - it should fire right up when put to 12 volts.
