I changed my blower fan control (in dash unit)new resistor and relay and still no go any tips

Doesn't it work in any speed ? Could have Blower Motor Control Processor if yours has automatic HVAC .
Or if manual it has blower motor resistor . Both are located under passenger side dash . Remove insulator panel under the dash if it has one !
ORO How to replace blower motor resistor in Chevrolet Silverado

2005 Chevrolet Tahoe Blower Not Working

Processor? This system consists of a control unit ( switch/selectors ) a blower motor resistor and a blower relay. If the blower fan is not working on all speeds, suspect a resistor ( common problem ). If the fan is inoperable, possible fan motor,fuse,relay,wiring and in some cases the resistor as well. The resistor is located under the passenger side dash area close to the heater motor. The wiring coming from the heater motor will plug into the resistor

It would help to know the make and model. Different manufacturers put them in different places and mount them different.

Most likely need a new blower motor resistor

Hello Linda! Replacing the HDM relay for the low beams will not trigger any of these problems. If the blower isn't working, you probably need to get a new blower motor resistor (for manual controls) or blower motor module (looks the same) for automatic climate control. To access, need to remove the plastic kick panel near your feet on passenger side. After removed, look up you'll see the resistor, it's about 4" long with 2 small screws in it. You'll also need to drop the glovebox door to remove the connector from the resistor to the motor. Suggestion- buy a pig tail for the resistor also, these tend to melt. Very common problem. The ABS dash could be a bad wheel hub assembly or a hub starting to go bad.

I would replace the blower motor resistor first then see if that corrects this. The resistor is located next to the blower motor under the dash.

If your fan is not working, its almost certainly the blower motor resistor. Also called blower control switch. They go out a lot on Civic from the 90s. Its under the dash board on the passenger side near the blower motor.

it sounds like the blower resistor/module is bad. It is located either behind the glove box or under the passenger side of the dash near the blower motor.

Manual climate control uses a blower resistor to control fan speed. it will have 5 wires going to it. A tan. lt green, lt blue, an 2 black with tan wires.

Automatic climate control will have three wires going to the blower motor module.

Heres a how to tip that may help explain what is going on

The blower motor fan is controlled by the blower motor resistor.Its the resistor which controls the fan on respective speed which you select.But if the resistor goes faulty,then it will not be able to set the required speed which you set for fan,so it works on high speed only. In this case you will have to replace the blower motor resistor. Check fog for the location of blower motor resistor location:--- see part number 8 in the diagram below.

The blower motor resistor is located next to blower motor under the dash.Its fitted with 2 screws and a wiring connector.You have to remove the screws and wiring connector and take the resistor out and place the new resistor in same position and connect the connector as well as screws. ------------------- this should help.Thanks.Helpmech.

there is no relay for the heater fan it's a 15 amp fuse and is on the accessories circuit. the reostat is responsible for all 3 speeds .with the key off there should be no voltage to the blower motor whether the fans speed fan switch is on or off. the fuse will be located in the fuse paneleither on the drivers left side in the dash or underneath the dash in the fuse block. you have a short in the harness that is under the dash and most likely it's a bad plug on the harness. your going to have to do some searching but that's where the problem short is... please rate
