Look under the hood and unplug the blower motor. Then replace the fuse. It should not blow the fuse without the blower connected. If the fuse blows again there is a short before the blower motor. There are several Black power boxes, usually under the hood on the Drivers side, the A/C relay may be burned out.

If the fuse does not burn out, replace the Blower motor. You can get one from a Salvage yard or Autoparts place. If you still have problems and the Climate Control panel is lite, there is a self-diagnostic feature which is run by pushing some of the control buttons in a particular sequence.

The codes for this sequence is different from the Master computer.
It may also reveal problems only a Technician can fix. So try the Blower motor first, A/C relay second, and hopefully this will get you going.

It is the blower motor,or the blower relay module,near the blower motor,and check the ac/heat control unit,if the blower ,and relay module turn out to be good.

Follow the wires from the blower motor back to the blower motor resistor, normally only a few inches away and held in by a 7 mm screw. Replace it

AC/ Heat is working defrost not working


sounds like a short some where, start by replacing fuse, leave a/c off, turn heat on, does it blow fuse? if yes then bad blower motor. if heat rruns then turn on a/c if that blows fuse then you might have bad a/c compressor . start there. hope this helps.
