Yes. Hot water comes from the water heater. The blower motor propels warm air around the house through the duct-work, but is not connected to the hot water heater in any way.
you need a new blower motor resistor with auto temp control
Chack the speed control switch and the resistor that controls the speed of the motor
blower motor in dash was not working replaced it still not working now what
If you are sure that everything is working correctly then check the ground going to the blower motor assembly.............. Which goes through the blower resistor.
replace the blower motor switch
Ground the motor housing on the new motor and see if it works then
First you have to see if your blower motor is working or not. If it is and still you have no heat then your heater-core is blocked and needs to be replaced.
You will need to replace the blower motor control unit located inside the blower motor housing, this part is not the same as the part on standard explorers, it is not the same blower motor resistor.
by the blower motor there is a resistor connection, you will find it melted the blower motor is bad. it draws to much power causing the connection to get hot and melt and burn. you will have to change the connector and the blower motor. the blower is still working but its drawing to much power, the motor windings are shorted out inside. disconnect the connector from the resistor and you will see it.
You still have a blower resister assembly, wiring, and a blower motor itself, in that system. Any one of those could have a problem. You need to use a test light at the blower motor connector and see if you are getting both power and ground. If you are missing a ground, most likely you have a bad blower resister assembly. If you are mssing power, check fuses and wiring. If you have both power and ground, and the motor isn't working, you need a blower motor. I have also found that sometimes tapping with a screwdriver handle on the motor will make it come on, and if that is the case, then again, you have a bad blower motor.
I have changed resistor a d blower motor still not working, maybe i missed a fuse or could the control switch not work?
Try checking the blower motor fuse, it may be blown. Also, check the wiring harness for good contact to motor connection.Last, replace the blower motor , ~$30 and 20 minutes to replace it, watch for AC lines when working near them. Good luck!!
