Blower motor not working

[jkdon]

Can someone help me out with this one. I have a 97 LS and the heater blower works when it feels like it. Some days I turn the switch, and nothing, after the truck warms up I have heat. Does this thing have a blower motor resistor?

thanks

On my 99 blazer, it is located on the top left of the blower motor cover by the fire wall. your hi speed should work. I just lost my two lower speeds. Check your connectors at your blower motor and resistor to see if they are loose or dirty.

If it is the resistor pack, only the high will work.

If it won't work on any setting, you have a bad blower motor or switch.
