BLOWER MOTER IS LOCATED WHERE
The complete removal is shown in this youtube video.

So you're getting heat but no blower to circulate the heat, right? It's also possible the fuze is blown to the blower motor, the switch that adjusts the speed of the motor could be damaged, or its resistors that limit voltage, to control speed could be "open" (burned up). I would check many of those before replacing the fan..
The heat is controlled by a valve that allows water to circulate through the heater core. If the fan is blowing cold air, check the valve, or blow water back and forth through the heater core to clean it out.

Check out your Earths...nearly always the problem, check and clean.

It is on the passenger side, you have to remove the black plastic kick plate, below the glove box, to expose it (held in place with 2 latches and 1 push pin). The resistor is in front of the blower motor ( sandwiched between the motor housing and the firewall) it is tricky to get to, i think when i changed mine i didnt replace all the screws as they were difficult to remove and even harder to replace. Good Luck, Mike

Aside from the obvious fuse or relay in power supply, it could be the blower switch, resistor pack usually located in heater box that contols speed, or the blower motor itself. Unplug wires to blower and measure batt. voltage with switch on. If voltage present, use ohmmeter to test blower resistance. No resistance, motor burned out. Check wiring for a cut/brake in circuit.

It is under the passenger side of the dash, I think what your looking for is the resistor. It has 2 screws holding it in, about 5 or 6 wires plugged into it in one harness.Good luck.
