Blower motor or blower motor resistor
When I turned the heat on in my truck I noticed I
didn't hear it blowing when it was on high. No
matter what speed it is set to I have a very weak
stream of heat coming out. I would love to be able
to fix this myself but am not sure where to start. I
assume it's not a fuse because there is air (but
could be wrong). I am not super car savvy so any
help would be greatly appreciated.
