The blower gets it power from the #35 fuse ( 40 amp ) in the under hood fuse box, if the fuse is ok then there is a blower motor controller it is located under the right side of the dash next to the blower motor, run a jumper wire from the red wire to the purple wire at the blower motor controller if the fan runs replace the controller, if the fan does not run
replace the fan motor....good luck

let me know if there is any thing else you need.

The fan stopped working for the rear AC/heat in our 2003 odyssey. Checked 40amp suqare fuse under hood and it tested ok. Is there a fuse or breaker for the rear fan motor?


The large fuse you checked is for the rear fan blower motor. The fuse you need to check is for the fan motor relays and rear mode control motor. It is fuse No. 3 (7.5A) located in the driver's under dash kick panel fuse box.

If fuse No. 3 is blown and you replace the fuse and it blows immediately, you'll have to check the five relays and the mode control motor all located near the rear A/C unit in the right aft sidewall. Most likely, the mode control doors have become jammed and that is why the fuse blows. The doors shift air from overhead vents (cool) to floor vents (heat).

If the fuse is fine, the trouble is probably with the blower motor itself or the wiring to the blower motor is broken, or there is a bad ground.

2005 Lincoln LS a/c blowing out hot air. Stopped blowing out cold air from one second to another. Where at what number is the fuse for the AC?


there are many thing beside a fuse, it may be low on freon or a bad low preasure switch and more ,you are right to start withthe fuses, then have the freon checked to make sure there enough in the system,you may have a leak. the fuse is a 10 amp fuse and its located in the aux fuse box in location F1-O1, here a diagram to help you, this fuse box should be under the hood, sometimes they put them under the dash on the pass/side.hope this helps.

Feel the hoses going into the heater on the firewall. If one is hot and the other is cool, then the heater control valve is not working for whatever reason. Check the flow valve.

Air and heat not blowing air through vents


Either Your fan switch is burned out or you blower motor is no good, your blower motor is on the passenger side under the dash. Before you replace any parts you need to check your fuses and relays under your hood and in the car. Usually if your fan switch goes bad you will still get some air blowing thru the vents, so my guess would be blower motor, If its not a blown fuse or relay.
