I replaced both resisters still no heat all lights come on when you push the bottons but blowers don't come on

The heating pad in the seat finally died.
My drivers side did the same thing but i havent gotten around to replacing it yet.
Ebay sells new heating pads if you want to replace it yourself.

you don`t say if you checked the fuse for the blower motor. if its good then you may want to check the powers and grounds at the blower motor. if you don`t then you need to back test the circuit until you fine were the lose of voltage occurred.you say you replaced the power relay next to the motor do you mean the resister block. if not then your problem may be the resistor.it sounds like you just threw parts at it hoping and doing any testing.

A resister would only cause it not to work on 1or2 speeds, Not all of them, The Blower motor is shot (Probally) They don,t last for ever, There is allso a relay for them in the fuse block in the engine compartment, That might be defective,

well here's your fix next to the blower motor is the resister that controls the different fan speeds the resister burns out but before getting the new resister unplug the resister as the connectors over heat and at time also need replacement

UNPLUG YOUR FAN BLOWER RESISTOR AND THEN TRY IT AND SEE IF LIGHT GOES OUT,blower resister plugs are known to go bad and loose ground so there fore it pulls a grd from somewhere else,check blower resister plug for bad (Melted) connection

the resistor

Replace the Blower Resistor. (About $12).

The resistor might be good; I have found that the terminals corrode, create resistance and sometimes melt the connector (About $100). Check the resistor before replacing it! If the connector gets fried, solder pigtails onto the good resistor and use Marr connectors to attach the pigtails to the existing wires,

The blower motor is shorting out.Replacement is the only option.If the speeds don`t work,replace the blower resister also,next to the blower motor.I hope this was some help to you.

The low speeds(all of them) are distributed threw the fan speed switch to the blower motor resister.The resister is the problem.It is located very near the blower motor.It has two screws mounting it to the blower box.It has a plug in with about 5 to 7 wires.Unplug this plug to the resister.Remove the screws.Pull the resister toward you,it mounts and rest inside of the blower case,this is how it is cooled.Now when you replace the resister,replace the blower motor.Even if the bower motor is running fine, it is pulling to many amps for the resister.It will happen again soon,if you don`t replace the blower motor.If I can help you any more,please let me know.

The blower motor resistor is out and it is fairly inexpensive to get replaced around $25.00.
