'96 RAV4 AC/H fan has quit after one setting has been dead for a while. My question: is it the fan motor, is the relay below the fan for the fan or is it the switch that is bad? I figure that you folks have the conventional wisdom and experience with this problem. I did push on all the connectors and pulled and pushed that relay, the fan started and ran for 30 minutes. Thanks in advance. - Allen
Help! RAV4 heater fan

Besides the items you listed, other possible causes are the resistor pack and the wiring.
If you want to properly identify the problem, you should invest in a volt/ohm meter if you do not already have one.
If there is another relay identical to the fan relay, you can try swapping them to see if the swapped item starts acting up, or you can pull the relay, apply 12 volts to the control voltage, and see if there is continuity through the switched side. If the relay is passing power, then check for power going into and out of the resistor pack. I suspect that the resistor pack is the problem.
OK I will poke around with the tester. Where is the resistor pack?

In the fan housing, I'll guess.

That is the it was on my FX. Had to replace the fan. Thanks. - Allen
I do not know for sure about the RAV4 (I have not got mine yet), but on my former Corolla I unscrewed the resistor pack from the fan housing and repaired the broken resistors with crimping cable connectors because normal soldering will probably melt.

On every car I've seen, the resistor pack that controls blower fan speed is in or in front of the blower.
