Its all in the glove box, open it and read the operators guide.
see fuse section.
buy one or get one free on line, google for it.
its also in the FSM. book.
or at

The Fans are controlled via Relay, and the PCM on newer cars controls that in complex ways.
the front fan is called the A/C condenser fan the rear fan is RAD fans.
the FSM coves the tests for each and ALL steps to find what is bad.
it only takes the FSM and DMM (voltmeter ) and 15min work to see who an what is bad.
(so we look at the relay, fuse good)
we check all 4 pins with a voltmeter. bingo we know.
ask more questions, can show drawings, after fuse are good.

Keep blowing the A/C fuse

BY you references to what you have done you have eliminated to fault to the front blower . So I suggest that you concentrate your efforts there. The motor be seized up and is drawing excessive current just to work. There may be a problem with the motor speed control shorting out,or a power wire to the motor worn though and shorting out to an earth point.

My rear a/c dose not work doesn't blow .all fuses are good

Check the blower motor (under the dash on the passenger side, follow the wires from the control switch), the blower resistor which is directly connected between the motor and the the switch, or it could be the switch itself. Check for voltage to all three parts, make sure you ground the negative side of the voltmeter to either the battery or to the car itself when testing. I am assuming that the rear heat doesn't work either with having you check these three parts. Let me know how this works out for you. Benjamin

Heater fan on 2002 Yukon does not operate in front, only rear.

The front blower motor is controlled by the blower resistor module.This is usually the problem with the front blower not working.I looked up the schecmatics and I don`t see separate fuses for the front and rear.But the fuse for the front blower is in the under hood fuse block.If this is good then The problem is probably the resistor module.It is next to the blower motor.The connector from the resistor connects to the blower motor.If you want to confirm this you can check for power and ground at the blower motor connector when you activating the blower switch on.This can be done with a test light.Make sure you have power going into the resistor module also.If you have power going in and no power at the blower motor then replace the resistor.Hope this helps.Good luck.

My blower motor stopped working, front and back of van.

My rear blower motor stopped working and my Brother took the unit apart. He found out that the fan blade had seized up the unit. After he took out blade and sanded down blades, it worked fine. However, I am not sure about your front unit. Good luck.

Front fan motor for heat and air does not blow.

The fact that your fan started working by itself makes me suggest that your problem could be a blower motor resistor switch. You can look up the location with an internet search using your year and make of vehicle and the part name.

If your van is equipped with this part it has a history of intermittent operation across many product lines. Although many parts stores do not allow electrical parts to be returned if they are not needed, the part has electrical connections which can be plugged in to test the part before installing. The effects should be immediate.
