rosco Posted April 12 Share Posted April 12 (edited) I have a 2011 Fusion Hybrid with dual climate. My blower motor was shutting off randomly for a while and then just stopped working all together. I pulled it out, looked at it and put it back in. After reinstalling, it started working again without issues for a few weeks and then died again. I've seen people saying it's best to replace the blower motor AND the resistor at the same time. My only thing is I'm thinking my resistor is just fine. When it was blowing, it worked on all fan speeds. When it stopped blowing it didn't work on any fan speed. Also, looking under there I can see that the resistor has more than likely already been replaced at some point. The wires have splice connectors and the plug doesn't have any corrosion or burn marks whatsoever and looks just fine. Do you think I'm ok to replace JUST the blower motor? The resistor is another $155 and I'd rather not spend that money if it isn't necessary. Edited April 12 by rosco 0 Quote Link to comment Share on other sites More sharing options...
andyross Posted April 13 Share Posted April 13 The blower motor is usually fine. It's the contacts in the connector that plug into the resistor that overheat and melt the housing, causing poor contact. That melted plastic can coat the resistor contacts, or cause oxidation. There is a connector repair kit that has a new connector with tighter connectors, and possibly better plastic that can stand the heat. The new connector does require cutting the old connector off (ONE lead at a time) and soldering to the new connector's pigtail. If you unplug the connector at the resistor, look at the connector to see if you see a melted connector. If so, it needs replacement. You MIGHT be able to get some extra life if you remove and look at the contacts in the resistor, and you can scrape off any melted plastic. I had 2011 Fusion SEL that started doing that. I bought a replacement resistor and the connector, but never got around to replacing it. I had cleaned the contacts and with some careful adjustments, it worked 99% of the time. I have since sold the car, but still have the parts. The connector is Motorcraft WPT-1285. 0 Quote Link to comment Share on other sites More sharing options...

I ended up replacing the blower motor only and its working perfectly now. 0 Quote Link to comment Share on other sites More sharing options...
andyross Posted April 19 Share Posted April 19 That was good luck. The only issue I remember with the blower motors is that the bearings would start chattering and chirping. 0 Quote Link to comment Share on other sites More sharing options...
WKelley Posted April 19 Share Posted April 19 It is not uncommom for a bad blower motor to take out the resistor/wiring plugs but that does not mean it is a guarantee. My blower makes a bit of noise when it's cold out but so far it's been OK. I really need to change it to prevent wiring/resistor issues though. 0 Quote Link to comment Share on other sites More sharing options...
