So, just recently replaced my radiator, everything worked properly when tested after.
just the other day the temp went wayyy up and I did some simple checking around. I haven't played with the wiring because when I turn the a/c on, the fan also turns on.
I can only figure that the fan switch connection is interrupted somehow since the a/c activates the fan and everything cools fine after. suggestions?
easy test, just ground the green/white wire at the temp switch. The fan should come on with the key at that point, if it does bad temp switch, if it doesn't bad wireing.
