How to change fuse for ac/blower - Cars & Trucks

Replace the blower motor relay,it's next to blower motor..

Check for power to blower motor if ok then replace blower motor.

there is a TSB for a noisy blower motor and not working except on Hi, both cover under 36K miles, repair includes replacing blower motor and or resistor block and harness, judging your problem can be a bad resistor block and harness. hope it helps

That fuse sounds like it powers the ac compressor.
The blower motor usually takes a 30 amp fuse.
Does the blower motor work if you hook it to direct voltage ?

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.

You mean the blower doesnt work because if it was just the blower you would still have heat and ac, It would just take long time to feel the change because no blower is pushing it out. If thats the case check that you didnt blow any fuses under the hood. in the fuse block. Your owners maual will tell you what fuse goes where.
If the blower is working then you should have either heat or AC to some degree and maybe the blend door is not switching (jammed) or the climate control switches are broken or if you have Automatic climate control then maybe the module is broken. There is a Technical Service Bullitin on the blend door issue which entails replacing the hole box ( its called a Heater Manifold) which can get pretty costly if its that.

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.

Check Fuse #3 in the under hood fuse block it is the only common connection I can make.

Blower motor or resistor.

it's either a fuse or it's a bad blower motor, it could be a bad blower motor resistor but usually you'll get either high or low only, so if you have nothing on any speed, high low etc, and all the fuses are ok chances are it's your blower motor.
