THE HEATER AND BLOWER RELAY. IS LOCATED ON THE BLOWER MOTOR HOUSING IN THE PASSENGER COMPARTMENT.ON 1999 THROUGH 2002 MODELS. AND IN THE FUSE RELAY CENTER IN THE ENGINE COMPARTMENT.ON 2003 AND LATER MODELS THE HVAC FUSE IS LOCATED IN THE FUSE RELAY PANEL UNDER THE LEFT SIDE OF THE DASH.
Main fuse block for fan may be under the hood or a relay may be bad sometimes in the same block or lined up on the firewall passenger side

if you have cold air in the rear then it isn't the a/c compressor. if no air comes out of the front vents the it is either the blower motor or the blower motor resistor.

yes, all blower motors have them to control their speed, High, medium, low.. etc. I earn nothing by helping you, but my rating, a fixya rating and I will walk you through this

I would have to say the resistor also. Cheap part and the labor is free when you do it yourself. It should be located behind your glovebox.

The first thing I would do is check to see if a fuse is blown or bad relay. Then I would unplug the blower motor with a test light make sure you are getting power to the blower located on the far passenger side of the vehicle under the dash if it has power and good ground then suspect vaulty motor. If you are not getting power at the plug then you might have a bad switch or resister. If it does have a blown fuse remember they usually blow for a reason like faulty wiring or even a in the motor itself. I would also recommend that you change the ac cabin filters behind the glove box if they have not been changed most people neglect them on that vehicle because they are a little more difficult to change, after removing the glove box there is a metal bracket in the way of opening the cabin filter compartment. They wont cause a blower motor to not work, however they do restrict airflow to the evaporator and they protect you from pollen, dust, and even exhaust gases. Hope this helps.

I had the same problem, I changed the resistor that is located behind the glove compartment and it is all good now. That resistor doesn't look like a resistor when you look at it. To reconise this item, there are two connector attached to it, the one from the blower motor on which there is a green wire and a black wire. The other connector attached to the same resistor consist of 4 wires of diff colors.
