04 toyota 4 runner shifter makes a noise like a fan hitting something then goes away after i shift it back and forth a few times?

Fan clutch most likely went bad

Hey Jane, .. hhhmmm..Only does it in 2H..not 4H... this tells me that it is in the front wheel drive line..(the noise quits in 4H)..obviously something in the front drive line is loose or worn out... THIS could be a safety issue... PLEASE take it to a qualified professional for a diagnosis...
good luck..

I cant open my2003 Toyota 4runner dikies, can anybody help m

bad spark plugs and plug wires

You could remove the serpentine belt and see if the noise continues, then check each component one at a time.
You describe a slipping belt because the alternator pulls hard for the first few seconds after you start the engine.

your flex plate is going out and it sounds like you need to relace the tranny fluid in it drain the old and put in new i beleave the fluit type is dex tron 3

Make sure the negative battery cable is connected tight to the engine.
The problem might also be the ignition switch itself.

Some vehicles I have had to wire an accessory relay to the starter, to give it a few more amps\volts to make them work.

You should be able to remove just the fan blower from under the passenger side dash and clean out the housing and the blower wheel

It could be a pully bearing going bad, or your power stearing pump. next time you start it when it's cold try moving your steering wheel left to righ and see if there is any changes. The next time try removing your belt before you start it and see if the noise goes away. The belt could be warn out and hard itll it warms up and soften up. Start with a new belt. Good luck

If its a 5 speed i would say check ur throw out bearings on ur clutch.
