I have replaced the resistor pack on my '05 at least three times. The last one lasted about three weeks. Soooo, I figured the blower motor was drawing too much power and changed that out, (it was squeaking anyway). Two days later, driving along, suddenly start seeing smoke coming out from under the dash!! Turned the fan off and it went away!! Got home, got under the dash, tried the fan...... nothing but high speed again.

Tried to pull the plug off the resistor pack, couldn't get it off! It welded itself right to the resistor pack.

I did get it off the resistor pack, completely melted the two outside connectors, wires were burnt an inch up from the connector.

The new harness has much larger wires than the original did.

Oh well, live and learn!

Now I get to eat dinner then go clean out the blood.
I found one in my blower too. Now to find out how it got in, and screen off the entrance!

Just did mine, great and super easy to follow write up, I found it easier to cross hands when manipulating the bump stop things right for left , left for right. It felt more natural. Anyway one of the wire blue/grayish colored wire look was a little burned up looking, as was the connector on that single outermost pin. I plugged it in and it worked fine. I'll probably need to do the upgraded harness soon. Part was 8.00 on ebay shipped, so if I need another mehh who cares. And yes this job is 10 minutes tops - Don't be afraid it is a 1/10 in difficulty.

I have the reverse of this, plenty of air on lowest and intermediate settings, but nothing on highest setting. Could it still be resistor?

Help! :)

I found this post to be SO helpful, very easy to DIY with all the pictures. Any ideas on what else could cause the same thing? My AC would only work on full blast in my 2005 Grand Cherokee. We replaced the blower motor resistor but it didn't fix the problem, any suggestions on what to try next would be greatly appreciated!
