SOURCE: ac relay location in fuse box

you have to refer to the owner's manual. that is where they list the fuse/relay locations. if not there, you may need to refer to the diesel supplement book. but i think it will be in the owners manual. i have a 2002 f250 and that's where mine are.

SOURCE: Relay or resister. Blower motor only works in 2 of

Very likely the blower motor resistor. GM had a lot of problems with them and actually redesigned them because of this problem. I believe on your car, it is located way up under the dash on the passenger side but near the center, next to the blower motor. It's hard to reach, but possible, two screws hold it in. Have a look at the new one to get an idea of what your looking for.

I have a 2000 chevy blazer the blower works on 1 2 and 3 but it wont work on 4 I changed the dash switch and the resister but that didn't work


There is a relay in the under hood fuse box , blower motor relay .When switched to high it energizes the relay allowing power from the HVAC fuse /30 amp to flow direct to the blower motor. from pin 30 to pin 87 , if you look on the side of the relay there is a diagram .For all other speeds the current flows from the switch through the resistor through pin 87a to pin 30 on to the blower motor ! Check the HVAC fuse in the under hood fuse block .IF the fuse is good check for continuity between the fuse side with out B+ that means pulling the fuse and using a volt meter to see which side has power and checking the side that doesn't have power to pin 87 at the relay socket ! Probably a bad fuse or stuck relay . Pull that relay and try a different one. You can get wiring diagram at www.bbbind.com click on technical information ,then click on Technical Service Bulletins & Wiring Diagrams .then on next page go down to the bottom and click on I agree . next page click wiring diagrams ,then just fill in you vehicle information .then HVAC system . click on diagram, then you will see 7 links , click on the 5th one and that's the diagram for the blower motor circuit !

2000 Ford F250 Disel: Nothing works on the panel for the a/c heater. The fan does nothing when you change speed there is nothing that comes out, there isnt any heat or cool, and when you turn the dial...


Pull the wires from the blower. Throw 12 volts and a ground to it(red is B+). If it comes on, it is good. Replace the controller. If it was the relay, some sort of blower speed would have happened. There are other wires to check, but you would have to loose other things to go this direction. Like accessory and ignition.

2005 Ford Expedition heat/ac blower not working


I would start if you haven't already by checking the fuse. Below is a fuse layout diagram for your vehicle. The yellow arrow is pointing to the 40 amp fuse for the blower motor and the red arrow is pointing to the blower motor relay. If the fuse is good and having someone helping, while touching the relay with your finger have the other person turn the A/C fan on and see if you feel a click inside the relay. If you do not you may be dealing with a bad relay. You can also check to make sure you are getting power at the brown and yellow wire at the blower motor itself. Use a separate ground than the other wirw at the blower motor connector. You should have battery voltage there. If all is good so far you can put direct power and ground to the blower motor to see if it works and if it does you may be looking at the blow motor resister or the controller. I would need to know if you have a manual or automatic climate controlled system in prder to help further. This is all assuming you are talking about the front A/C system and not the rear or aux. A/C system. Hope this helps.....

My Blower motor for my heater on a 99 ford escort is not working.Is it the motor or resister that is gone??the fuses look ok where is the resister located can you send a diagram


look in passenger foot well on blower case for 4 wire connector.



Behind right side of I/P, A/C-heater plenum


resister bad would still allow high speed. may be blower motor.

  • The blower motor does not operate/does not operate correctly
  • Open fuse.
  • Tripped circuit breaker.
  • Circuitry open/shorted.
  • Heater blower motor switch (18578).
  • Heater blower motor switch resistor (18591).
  • Blower motor relay.
  • Blower motor.

Blower for heat.


If the blower is totaly not working it could be a bad motor or a loss of power (or ground) to the motor. There is a blower motor relay on the power distribution box on the right innner fender. There may be a fuse for the heater circuit, also. Power also goes through a blower motor resister that controls blower speeds. If any one of these are bad it will (can) cause the blower motor to not work. I would first check all your fuses. If you have the ability to check for power continuity (with a test light or multimeter) I would check to see if the motor is even getting power. It is also possible that your heater control switch is not sending power to the relay. Electrical can be hard to track sometimes. Good Luck.
