Check with the Dealer to see if your Vehicle is still under Warranty. They vary from 2 Years to 3 Years and miles up to 36,000.

Next, the part is the Blower Control Resistor. Usually all you need to do to find it is follow the wires from the Heater blower motor back to a connector on the Underhood ductwork. There should be 1 Electric connector and 2 screws holding it in place. 90% of the part is inside the Duct and the part is about the size of a pack of Cigarettes. Sometimes you have to disconnect heater hoses to get enough clearance to remove it.

The nice thing about replacing this part is to test the new one all you have to do is connect the new part up to the wire connector. If that was the problem your Blower will instantly start working once you turn it on. Then you can switch out the defective parts.

The part can cost from $50 to $150 and they are obtainable from some Salvage yards at a lower cost. However if you are under Warranty you get free parts and labor.

Overheats unless ac is running

The thermostat may be stuck. If it dosent open then the engine will overheat. If you turn the ac on then the air rushing around the engine will help cool it down. Replace the thermostat and it should fix it

HVAC controls overheating

fan motor most likely at fault, low speeds cause extra heat in motor

My 2004 grand marque's blower motor stoped working is it the blower motor relay or the resister?

If 1, 2 & 3rd speed not working, it is resistor (assuming you don't have EATC). High speed will work if fuse is ok and resistor is burned.
EATC = Electronci Auto Tem,p Control (Digital)

Abs light on, 2004 moutaineer

You most probably have a bad speed sensor on one wheel if it is intemitent try unpluging each on and repluging them, sometimes just a bad connector, If this doesn't help get someone to scan the codes for you and it will tell you which sensor is the problem. Keep in mind that until you fix this you can not depend on your ABS system. Normal braking should be fine though.
