Blower issue with a/c...help please
I need some help I am working on my 99 dodge ram 1500 van. The blower for the a/c only works on full blast the first three settings do not work. I replaced the switch (best way to describe it) on the air box under the hood which contains the coils and resistors and it worked briefly. I also replaced the relay attached to the air box as well thinking that may be the problem. im out of ideas short of buying a new blower motor, any help would be appreciated.
