Sounds like blower resistor card has failed , it mounts close to the blower fan in the hvac housing. 2 screws and the wire connector is all it takes

Heater blower only works on high


Most likely the blower motor resistor or the fise for the low speeds. The high setting for the blower motor is on a separate circuit than the other lower settings.

My heater blowers dnt work and i need to knw where i can locate the resister blocks for my heater blowers so i can ghange them


Its located under dash,or near glove box.

The dash panel lower side has to be out.

HEATER BLOWER MOTOR


Its faulty blower motor resistor. The low and medium speed on blower motor is controlled by resistor and its actual speed is high. So because resistor is not working, blower motors actual speed which is high is working.


It can be faulty blower motor or faulty blower motor resistor. Get the blower motor inspected. If it's faulty it has to be replaced.

You have a defective heater blower resistor, the part is located next to the blower motor in the air ducting that it uses to cool the resistor.

Heater does not work


Check heater fuse.
If fuse good - could be a failure of the blower fan motor or blower control switch.
If fuse bad - bad blower fan motor could have blown the fuse.
DO: check fuse, then blower motor.
Pricing: new blower motor: Duralast PM270 $43.99
new heater control switch: Duralast SW229 $46.99 (without
A/C).
I'd expect your blower resistor to be good - when they fail, the blower only will work on HIGH setting.

My 02 Stratus heater only works on high. Any idea


Your blower resistor is bad. It controls the mutiple speeds to allow you to go from low/med/high. When it goes bad you get one speed or no speeds....It's about $20-$50 at any local auto parts store. It mounted directly to the speed switch or on the heater plenum unit on the passenger side behind the glove box....

I'd replace blower resistor, usually found under hood on firewall on passenger side, or on duct work, inside under dash on passenger side,close to blower motor.
