Can a blower motor resistor from 2004 Honda Accord with dual climate control be troubleshoot?

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.

Hi! The speed control is defective.The terminal 1&2 could either b worn or burnt out.

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.

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.

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.
