I took my rodeo Isuzu out of 4w and now when I try driving down road it makes a windy sound

RTM , Read the manual yet. seem not
my guess, it car is PT 4wd, and not TOD fancy system.
so with PT (PART TIME 4WD)
4wd is for driving on ice. and dirt.
never on pavement ice free
or it damages the parts. winds up. when you turn like
this hear the damage ,increase, its saying why kill me./?

sticks in gear
or baulks at going in to 4wd.
transfer case cries in pain

this comment is not true if font locks are unlocked

but that is not 4wd, is it? .a1b1e992-7338-49a5-8900-5c0a3e3f182e.jpg

this is the trooper TOD (on left)
id bet your car is PT ,part time 4wd
you need to be on ice,
and i bet you are NOT. am I right/.
try reading your operators guide,
all warnings on this post are THERE.
this car drives same was as all PT jeeps.
same way, and same rules.

4 wheel drive lights flashes but then returns to 2wheel drive -- some time it will lock in 4w low but both 4w hi and 4w low lights are on --- have new tccm module.

It is the shift motor for the 4wheel drive - only problem is that a shop has to program the new shift motor to the blazer or it will keep doing the same thing

4 wd is engaged in 4wlo, but when i try to disengage it wont.

Try backing up straight about 50 feet and try it again. Sometimes drive line strain can build up, especialy if you've been driving on hard, dry ground or turning a lot. By backing straight up you relieve that strain and there is less pressure on the gears so they will disengage.

Won't stay in 2w or 4w high

4wd systems on these are abominable. most likely module and/or encoder problem.

Shifting into 4 wheel drive

For 4W Hi either be stopped or moving at a slow rate of speed (<20 MPH) and move your 4WD selector to the 4 Wheel Hi position.

For 4W Lo stop and move the selector from 2W Hi to 4W Hi then push down on the selector and move through N into 4W Lo.

Mini one warning lights

This is the flat tire light. either your tires are low on pressure or the flat tire light button is stuck down. if your tires are low refill to same pressure I usually use 35 psi. then start the car stay parked. depress the flat tire button located either under the ebrake or just to the right of the ebrake. hold for 10 sec. then drive car for 5-10 min do not drive hard. drive on normal roads 25 -35 mph then drive on the highway. If the button is stuck find some kind of electrical cleaner and just keep trying to clean it till it no longer sticks down.
