I don't have a diagram for a 2008. On 2005 models the blower motor relay gets power from a 30amp fuse.
When the blower switch is in the high position the resistor is bypassed and power flows directly to the motor. The motor is grounded to the car.
The fan relay also gets power from a 7.5amp fuse and is controlled by the HVAC control on the dash.
Do you have power into and out of the relay?

SOURCE: No Electrical Power to Heater Blower

First thing to check would be the fan speed resister, fan(blower-motor)relays, and possibly a bad ground. Start at switch on the dash and go to the relays and resister next.

SOURCE: front blower motor will not

This may be a faulty Blower motor resistor, usually mounted inside the blower motor air box, or defective blower motor. There is no single Relay for the blower motor.

Welcome to Fixya

There is a fuse box/relay under the hood. Check the box if there are blown fuse and relays that you need to replaced.

SOURCE: trouble shoot blower motor switch

Often times the problem is the blower resistor not the switch.
You would use a meter or a test light to check for power at the resistor and also the switch. The resistor controls power to the blower motor to adjust speed.

Use a jumper wire and jump 12 volts to the blower moter and see if it comes on, make sure that you have a good ground. If the motor does not come on then it is going to be the blower motor.. hope that helps mmkayyyy

My 1997 Mazda Protege heater does not blow air, i replaced and tested blower motor, resistor and fuses inside the cab. Still nothing

Before replacing the blower motor, you should have checked the motor's input wiring loom for power.
Do you have power here?

If you don't have power, then you need to check your blower switch output wires.

2004 Chrysler Pacifica Blower won't work

Usally when a blower motor resistor goes bad the fan still runs on high. The resistor lowers the voltage going to the fan to make it run slower. The high setting usually goes straight thru. Resistors are usually easy to get to, under good on the firewall or under dash passenger side. Cost about $24 at parts store. Replace with new if that doesn't work return it.

Heater fan not working

The three most common problems for heater fans are
  1. Burned-out blower motor resistor. This is usually located on the engine side of the firewall. Sometimes one section of the resistor is burned out but others are still good, so the blower only works on the highest speed settings. If you have a burned-out resistor, check the blower bearings to make sure they are not stiff and causing the motor to draw too much current.
  2. The blower is actually working, but either the intake vent is plugged (I've seen vehicles with the heater core completely blocked by dirt, leaves and insects that came in through the vent), or the heater door is stuck closed.
  3. The motor bearings have gone bad (see # 1). This can cause the fuse to blow, although the resistor usually fries first.
I'm not sure how your car's cabin environmental control system is fused. Check any fuse that might apply, such as Vent/AC, HTR, FAN, etc. Generally you can identify the state of a blade-type fuse by inspection without removing it. If you have a blown fuse, check the blower motor before wasting money on a new fuse that will probably blow. Like any fan, it's supposed to turn easily, and there should not be any roughness or side-slop in the bearings.

My blower resistor is always fail, I install a new one it's work a few weeks and fail again, I install a new blower moter and a new blower resistor it's work a few weeks and the resistor fail. The...

you can get a new resistor and you have to start the blower at hi always to avoid over heating in the resistors and protect the thermal fuse, the second after you had started the blower you can select any speed.

Heater fan has stopped blowing. Just before this happened a lound droning/whining noiuse came from front of vehicle.

From you're description I'd say the blower moter has
cooked a bearing. Check fuse #1 and #2 both are 15amp. They're in the fuse block behind the coin tray
on the lower left side of the dash. They usually go first if the bl moter locks up. To do a quick test unplug the bl moter, located behind the right side of
the dash. Turn the fan switch off and replace the fuses. Plug the blower in and turn it on, if it pop's the
fuses again replace the blower moter. Hope this helps.

I turn the the fan on for the heating but the fan

Sounds like a seized up (bad bearings) blower motor. It may not pull enough current to blow the fuse at the lower fan settings but does at the high one. Something could also be jamming the blower fan in its air duct.

Most blower motors can be accessed under the hood. Replace the fuse then put the blower switch on one of the lower settings (don't blow the fuse). Get yourself a good sized screwdriver and hit the back of the blower motor with the screwdriver handle a couple of times.

Sometimes (unless the blower motor has totally seized up) you can get it to spin and this will tell you for sure you need a new blower. Other than that, you can get a spare blower motor, remove the connection wires from the old motor and hook them up to the new one to test before you go to the trouble of replacing the blower.

Hope this helps you out... -Dan
