The AC and heat get cold and hot like they're supposed to,

Customer Question

The AC and heat get cold and hot like they're supposed to, but unless the fan is on full blast, nothing comes out of the vents So it's either not blowing anything at all or its going as hard as it can
JA: Have you checked the coolant level? Has there been any leaking from the hoses?
Customer: I think there might be one hose leaking but I'm just a teenage girl with minimal car knowledge It also makes a cricket/whistling noise in the vents
JA: What is the make/model/year of your car?
Customer: 99 Oldsmobile intrigue
JA: Are you fixing your Intrigue yourself? What have you tried so far?
Customer: I wouldn't say I do it myself. I have a boyfriend, grandpa, and auto teachers and that's it. I haven't tried anything, they just did a recall on the valve cover so I didn't mess with anything
JA: Anything else you want the mechanic to know before I connect you?
Customer: I don't think so

Hi. More than likely the blower motor resistor is bad. WHen the blower motor resistor fails, it only allows the fan to work on high speed.
