This indicate your blower resistor is not working

You can start by re soldering all point in resistor

As the blower resistor in this generation of honda accord

Is prone to fail with time.

You can google #2003-2007 HVAC Blower Transistor Repair# and you will find alot of pic to fix it

SOURCE: cooling fan only comes on when the AC is on. Have checked relays and fuse.

there are 2 fans 1 for the ac that only comes on when the ac is on thats normal.and the radiator fan that comes on when it reaches 160' to 180'degrees only on electric fans.u might have to reposition the wires on the fan.

SOURCE: Replacing Blower Motor Resistor

  1. Disconnect and isolate the battery negative cable.
  2. Open the glove box.
  3. Flex both sides of the glove box bin inward near the top far enough for the rubber glove box stop bumpers to clear the sides of the glove box opening, then roll the glove box downward.
  4. Reach through the glove box opening to access and disconnect the instrument panel wire harness connector for the blower motor resistor from the resistor connector receptacle (Blower Motor Resistor).
  5. Reach through the glove box opening to access and disconnect the blower motor pigtail wire connector from the resistor connector receptacle.
  6. Remove the two screws that secure the blower motor resistor to the evaporator housing.
  7. Remove the blower motor resistor from the evaporator housing.80ac4e54.gif

SOURCE: new climate control unit but when on blower not working for heat or ac

I'm assuming the problem is the blower motor isn't coming on or working. 1st, check the fuse. 2nd, remove the glove box or pull the 2 tabs that act like stops when it's open ( the glove box will open out further) and you'll see the power plug connector for the blower unit. Turn on the blower through the climate control (heat, A/C, or whatever) and wiggle the connector to see if the blower turns on. If starts working, then an easy solution is pull the connector off and gently press the prongs together or inward. Then carefully reconnect with damaging the prongs. This worked for 96 Mark VIII due to the fact the prongs were not "seating" correctly in the female connector. It's been about 2 years since I did this and the connection is still good. If wiggling the plug doesn't work, pull the plug, turn on the climate control (heat, A/C), and check for voltage to the plug. That's about all I can help with.

SOURCE: blower motor does not work

I had the same problem, replace, replace, replace. Check, check and recheck. What I found was the blower motor resistor, located in the blower squirrel cage area, two prongs and a curly wire, was bad. Took the new one back, (it ohmed out okay, continuity ok, all ok!) replaced it with another, and Bingo, problem solved. Frustrating to say the least. After two relays and a blower switch, and test, test and retest. It was a faulty resistor. Made in Mexico. And no guarentee, even though new, it works. Trial and error. Even the dealer parts are Honcho en Mexico. Thanks NAFTA. You gonna make us all welfare babies.

My porsche boxster 2001 is over heating and red light blinking


More than likely the cooling fans or fan for the engine is not working, ether because of a fuse or the fan its self or the temp sensor that controls the relay for the fan. So first check fuse, then check the relay, then if those two are ok, then hook power and ground to cooling fan, if fan operates then ether the wire from fan to control temp sensor is open, or the coolant temp sensor if open, faulty, sense fan is not working this causing the a/c to be inop and the over heating of engine , but only at stop and go traffic do to the lost of air flow across a/c condenser and radiator.

2004 crown vic. only 63K miles on her. AC/heat fan was sporadically working, now its done. AC was nice and cold, working fine. Is the fan a hard replacement if I were to find one at a parts yard?


Try to check the power and ground on the blower fan. If you missing the ground on the blower fan connector than most likely it is the blower fan resistor (controller), it is located under the hood close to back firewall behind left cylinder head.

Engine cooling fans only work with AC on


there are two fans, one comes on with the air con, the other when operation temp is reached . check fan fuse and censer if ok check fan motor.

Car over heats fans dont come on


Check fuse for cooling fan, check temperature sensor functioning for cooling fan, check relay for the fan (if you have one), check cooling fan motor circuit with resistance check (should read low Ohms, less than 2 Ohms beacause the fan is a powerful motor with 10-20 Amps).
If everything is measured O.K. you should check the wiring. Disconnect the connector at the cooling fan motor, connect a test light to the harness from the car (not to the motor side) and run the engine. Watch the temperature gauge and before you the boiling (overheating) the bulb should lit up. If not you should go back with this test step by step to the relay. The relay can be tested if you can find a same one on your relay board and swap temporary (e.g. swap the AC clutch relay with the cooling fan relay)

My ac wont turn off and only blows at one speed


faulty resistor won't make it blow warm air.
sounds like the climate control is bad.

Heater blower motor.,Highspeed only works..problem??


9 out of 10 times its the heater fan resistor doing this. it has wires that corresponed to diffreent speed settings for heater fan. the resistor is beside the blower motor, Your Kia Sportage Blower Motor Resistor controls the heating equipment in the vehicle by opening and closing the fan motor. The Kia Sportage Blower Motor Resistor allows the heating and climate control system to control the speed of the vehicle's cooling fan. its under the passenger side glove box. undo 2 screws and disconnect the electrical connector. thats it!!

WHERE IS THE BLOWER MOTOR RESISTOR LOCATED ON A 2006 EDDIE BAUER EXPEDITOIN? mY A/C AND HEAT WILL ONLY BLOW ON THE HIGH SETTING. IT HAS CLIMATE CONTROL AND DUAL CONTROL FOR THE DRIVER AND PASSENGER...


I found this wiring schematic at: http://www.f150online.com/forums/articles-how-tos/385953-replace-04-08-fan-blower-motor-resistor-emtc-hvac-3.html
It looks like it is located under the dash on the passenger side, and appears to be pretty close to the blower motor. The resistor or controller is different if you have a climate control system vs. a manual temperature control.
Here is a possible picture of the climate control module:
