My AC/Heater control will only work on high speed. I have replaced the Blower Motor Speed Resister which corrects the problem. The new resister allows the blower to operate in all speeds.

But, the new Resister only lasts 2-3 weeks before it goes bad. I've relaced it 3 times in two months. Any idea why the Resister would keep failing?

Have you checked the wiring and plug
also check if the motor pulling to must current
check the air flow around the resister

The plug and wiring appear to be good. No knicks or cuts. I believe I will replace the blower motor. I had someone tell me that it could be pulling too much current on the lower speeds. And, tonight, I found a reply to this problem in the Town and County forum. The responder indicated that if after replacing the resister, it fails again, the blower is bad. Thank you for your reponse.

Don't forget to replace/remove the in-cabin air filter. I first replaced the resister and it burned up in a few weeks. If the in-cabin air filter is clogged it keeps the air from freely flowing over the resistor and it will burn up repeatedly. The filter will drop out of a hatch below the glove box. I simple removed it and did not replace it.
