2005 Explorer XLT AC Blower Issue

[Djmorice]

I did a quick search for a couple threads but wasn't able to figure out my specific issue.

My AC blower isn't blowing on the first 3 settings, but when I turn it to 4 (high) it starts blowing cold and like normal. It seems like there are 2 different blowers or something, but I haven't been able to pinpoint the problem yet. Anyone know what I should check? Or is this something I just need to take in and get looked at?

TIA

Sounds like the fan blower resistor needs to be replaced. A full size Chevy pickup had the same issue at work as it would only work on full blast. They replaced the resistor, and it was good to go.
