Default Ac Blower fix

Thanks cdobis. The AC blower on my 2007 H3 stopped working today. Just happened to come across this fix doing a google search. Fixed and working in just a little while.

My AC went out yesterday at 32K miles. I was going to the gas station to fill her up. the AC was working great on the way there. After I got done pumping gas I started her up and no air. The lights come on the **** but the AC does absolutely nothing......not a sound.....not blowing a bit of air. Today is suppose to be one of the hottest days of the summer....ugh.

Default Parts On The Way

The blower went out on my AC while I was out of town on business. Luckily, my wife had her automobile too. So, she didn't have to bake in the 100+ degree heat. I found this thread and pulled the wire harness and resistor out from under the dash. Sure enough, the cable jumper (connector) was burnt. I went ahead and just ordered the wiring harness and resistor from the dealership. It cost me about $50 total. I decided against the fix posted on this thread for one reason. If for some reason I do something wrong or if this repair is faulty and causes more damage (like a fire) I might end up the creek without a paddle. Insurance companies won't pay if they find out the vehicle was repaired using an unapproved method. So, I just forked out the $50, if the new parts last for a few more years I'll be happy.

I'm just elated that I saved a couple hundred bucks by pulling the part myself instead of having the dealer run a diagnostic and also charging me for labor and replacing the parts.

Also, if anyone is having trouble locating the wiring harness and resistor they are located on the bottom side of the dash directly BEHIND THE GLOVE BOX (not the glove box door). You'll have to also drop the glove box door all the way down to access the connection points to the wiring harness, so you can unplug them. There are three plugs/connections total. The resistor is just resting in a hole that is cut out under the dash. You can pull that and unplug the cable jumper from it. That's where you'll see whether or not it is burned up.

I just wanted to explain that better for others because I was confused by some of the directions I read above from other posters.

Same happened to my Wife today. 100 degree weather and no a/c. I bought a relay first just to eliminate then checked on the site and came across this thread. Mine turned out to be just like your picture autopilot.
I really can't believe this ain't a recall !
Thanks Guys, your awesome !

Default Thanks Craig!!

I too had the problem with my AC blower going out on an '06 H3, and was skeptical of how easy this would be to fix. But actually it was just as easy as Craig had described, and now works as well as it did before. I have big hands so it was a little difficult to get the Blower plug removed, and back in again, but other than that was smooth sailing. Thanks for the Help!!

Default Differnt Approach

Great info...I took a little different approach. I cleaned the contact. I soldered a wire onto the one terminal only. I drilled out the melted plastic male connector and removed the wire. Then I plugged it back together with the wire running through the enlarged whole and connected it to the source wire.
