02 Honda Accord Radiator Fan

[rclint]

I have been working on my Honda all day, what a pain in the rear !! I have never had any problems out of any Honda's I have owned, however this one problem is really taking it's sweet time working itself out. My car (2002 Honda Accord EX 2.3L I4) while idling the other night ran hot, well not in the red hot, but started steaming out of the overflow, and temp gauge ran about 3/4 way up. No radiator fans working, so I check with meter for voltage, ohm etc general trouble shooting. I was reading all over the place, so I jumped straight from the battery, and still nothing, so I purchased the motor for the fan. The motor will not fit, so I check the motor to make sure no broken wire, something simple, and the motor spun right up on the bench. So I check the pigtail, so resistance however very little, so clean with contact cleaner, and nothing, it would not spin up through the pigtail... Ok no problem I remove the pigtail for tonight, and plan on replacing it with one of the automotive generic pigtails tomorrow. Then it done it again after straight wired to the battery, this fan motor is really driving me crazy !!

Now I need to find the part that fits my car, I can drive it like it is for awhile, as it's cool, I drive mostly interstate, and I don't need a/c now. I'm just stumped how both fan motors could go out, neither motor will spin up jumped straight from the battery now, and they would not to begin with, however after working on the radiator fan mainly it would spin up fine, then nothing. Any idea what could have caused the motors to go bad on both the radiator, and a/c fan ?

Any thoughts, help, and info on where except ebay I may be able to purchase a replacement motor for the radiator fan ? A bit of searching shows if the in stock fan motor does not fit from auto zone then it's hard to find the correct motor. I will check the other local parts stores tomorrow. Also any pointers on the best pigtails as I will need to replace these, and I want them all the same.

Rockauto lists 3 motors for this. One complete assy, with motor, fan, and schroud for 48 bucks. The other 2 are just the motors.
Do you have the Nippon Denso, or the Mitsuba fan motor ?
Denso replacement is $48, Mitsuba is $200. They look the same from the pics.

It does not have anything on the motor except these numbers, 12V then M9007. The motor I purchased, and tried is the denso, so that would leave me with a bad feeling $$$ wise. The denso looks like it would work, however the mounting flange/holes are not big enough. If they were 1" longer each I could just drill new holes, however it would be a major deal to mod the way it is. I'm looking at that site now thanks

I'd just try for the one that comes with the shroud and fan too. It should line up ok. It says that Honda used this one on civic's, and accords.

i feel ya. my motor was weak and i wanted it done fast, so i go to autozone, get a motor and the thing doesn't really fit into the bracked. the tabs were aligned correctly but the motor was a tiny bit too fat in diameter----so i dremeled it with a sanding drum and it slipped right in.....the only place I have seen good prices on OEM brand new fans for the 2.2 accord was a place on ebay. I think it was valeo brand but can't remember.

Joel, I ran into the same problem with the replacement fan motor from Autozone (Siemens brand), so I returned it for a refund. I then went to Advance Auto Parts and got a fan motor that fit perfectly. I later found out that the computer listing at Autozone is incorrect. The part number shown for the Mitsuba motor is really for the Nippondenso unit and vice versa.

If you're testing your motors with some of the harness plugged in beware a relay probably makes them go in series for low then in parallel for high. So your "ground" may not be a real ground, might go through the other motor first, etc.

Might be worth wiring in a high beam headlight to the car side of the wiring and triggering the AC to see if it passes decent current as well as voltage.
