I am having the same problem in my 2004 frontier xe king cab with 2.4 Eng. It started about 6 months ago so I finaly break down and buy 3 new belts and have them put on by a local shop. So I have been analzing what has been going on ever since, it still happens and I think I know why??? Since day 1 I have heard the clutch on the fan kick in ( happens when its warmer and you have blower on ) and when the blower is on it will sqeal when the clutch kicks in !   Soo turn turn off blower ( ac or heat,lights on makes it worse ) sqeal stops or quits very quickly!! As an Electrical relay burns its contacts ( Under a heavy load ,esp Dc voltage ) It will often times pull a high curent load and pull voltage down. Alt belt sqeals in responce to the added load that it cant handle. IE turn off some load ( blower ) it quits. Looks good on paper (and works every time for me ) but where Might I find this relay ( clutch appears to work  good????? ) Thease days money is tight sure would help if I could just replace relay and have this problem behind me :) 5 1/2 years 127k miles and I have put gas,tires and oil ( ok 1 air filter ) on this beast, what a value it has been !!!! Please help me Frontierguy your my only hope  :)
