switch or fan, 98 frontieer

[rdwr01]

Fan for heater or A/C on my 98 Frontier only work on high (position 4).
It won't blow air on any other setting. Would this be the switch itself or the fan? 4 cylinder engine if it matters.
A little history, fan has made a noise in the past when it is on but usually quited down and worked fine.
If it is the fan moter would it still work on high?
Thanks

Doesn't anyone answer these inquiries?

You need a new blower resistor located under the glove box. Go to any parts store and they should know what you're talking about.

nissandoc,
Sorry for the late reply I had computer problems but just wanted to say thanks.
The resistor was the problem
