Currently troubleshooting blower motor issues. Found bad motor, replaced it. However, the blower now only works when the fan switch is place to 4 (highest setting)
There are 3-4 wires from the fan switch to some type of element. (Heat sensor?) Continuity was good to all wires, however the element is fried. Can that cause the lower fan settings not to work?
Also took apart the fan control switch and all seems normal visually.
Thanks in advance for any help.

Replace the heater blower resistor. It is located near the heater blower, it is about 1" by 3" with a harness connector going to it with most likely only 2 screws fastening it in.

This resistor is famous for have failed when the first 3 settings do not work.

The part that I described as an 'element', could be a resistor. Same area as your description. Once part is off, there are 4 prongs that have coiled wires. Looks like there may have been some ceramic on them at one point, but it is beyond recognition now. Does that sound right?
And THANK YOU for your quick response.

Yes sir, that is it! To confirm this, go to your nearest parts supplier and ask for the heater blower resistor, he should give you one that looks just like it.

Keep in mind, if they are aftermarket, they MIGHT look a little different. Some have exposed coils and resistors, others don't. As long as the harness connector is the same and it fastens up, it will work!

Thanks. Already looked it up at advance auto, and sure enough, that is it. Was going to replace it anyway since it's obviously bad, but didn't know if it would affect the blower settings. Thanks again!
