I put new fans cooling and ac,, new fan relay. And new tempeture sensor and don't work my ac fan and cooling fan . I check the all fuses are in good condition .,only I have to change the auxiliary switch to see if that is the problem.,
I can't imagine why anyone would replace all these components that are easily tested with a simple test light? For example, you can't be sure of fuses by looking at them. You have to use a test light. You need to start at one end of the flow and work to the other. Might be easiest to start at the radiator temp sensor. If you shunt that, the relay should kick the fan on. If not, then check power to the relay at the relay. And don't forget grounds. For example, power to the fan is not enough. It also much have a good ground connection wire. You can get a test light at a place like Harbor Freight for $1.
