Any one know where I can get a new plug for the blower motor? What is it even called? I stopped by Autozone today and they could not find it in their catalog.

My blower motor works intermittently but works great when I can get the plug injust the right spot. The plug looks melted and I can see arching when I wiggle the plug when the fan doesn't work.

Thanks Coby,

Now to figure out how to get the old one off.

Any suggestions? I can get the blue retainer out but getting the terminals out is eluding me.

You have to insert a pin and push the locking clip. But those pins are probably no good anyways and you will need to crimp new ones on. Cut wires as close as you can.

Weird. My girlfriend's car is having the same problem, and this is the first link I see.

Were you able to fix it? I'm going to pick up a new one of the connectors linked earlier in the thread, but it'd be nice to know if there are any gotchas to watch out for.

This happens because people don't change their cabin air filters often enough. It gets dirty and blower motor strains and sucks more current than it normally would. If you are not going to change the cabin air filter regularly just pull it out altogether.

Sorry for taking so long, I finally fixed it.

I bought part EC266 from NAPA. Cost around $16



Here's what it looked like before I started.


I inserted a screwdriver into the tab on the left to remove the plug.

Cut off the old connector.


I used crimp on splices to connect everything. I wrapped the splices in electrical tape. I would have used shrink tubing but I didn't have access to a heat source when I did this.



Here's the finished project. I tapped the wires up out of the way since my kids like to put their back packs and feet up in this area.



Finally this is what the old connector looked like.

Hope you cleaned the recepticle pins as best you could.

Also next time you do a splice, it is always best to offset your unions.

I didn't think of cleaning the receptacle.

Would spray contact cleaner cause any problems or should I just use a little sand paper?

I've left plenty of slack in the wires to offset the unions. What are your thoughts on me taking the time to change it?

Yeah you should at least scrape the black carbonized metal. Maybe add dialectric grease to stop the arcing.

My niece's cobalt blower quit working. I went through the whole system components and couldn't find anything bad. Pulled the resistor, set to high, nothing. Pulled the plug off the motor and put 12v directly to it, yep fan works fine. Fuses and relay all test fine. Pulled the plug off the back of the speed selector switch, continuity through each of the four settings. Pulled the BCM out, opened it up, but no corrosion or anything obvious, so I couldn't rule it out, but it didn't seem like the culprit. Then I check the resistance along the black wire from the back of the speed sector switch plug to ground...high resistance. Hmmm, the first clue after a long day of frustration. Traced the wire around to this guy:



Tried to pull it apart (releasing the lock of course) and couldn't do it...another clue. Checked resistance from the speed switch to each side of this plug. Minimal on one side, high on the other. Long story short, cut that sucker out, spliced the wires back together and everything works great. BTW, I replaced the cabin air filter. It was the dirtiest thing I've ever seen...yep, another clue.
