ok so my thinking is that the fan blower is the culprit of the blower resistor shorting out and not just rain water itself. my thinking is due to exposure of rain in the blower and the bearings lubricity being compromised and creating much more resistance at start up at lower speeds, causing the blower resistor to heat up way beyond what it was intended to do and shorting out. looking at the new one vs the old one it has no burn out spot on it, now i'm not sure what to think at this point. rain has nothing to do with the latest problem with the blower resistor, so droping the motor and lubing it up is on my short list if not replacing it, but it ticks me off to buy a new blower resistor again. $$$$$

 

Not as easy as you may think, you have to cut the old one out then bolt the new one in. You can't just unbolt the factory motor it's part of the housing.

 

do you know of a link that shows in detail how to remove and replace??

 

????

 

there is good how to--- i also ordered new motor but havent swapped it yet. makes irritating ticking sound...but still works...

Keep an eye on your PM box.

 

well ...it has been the sound, i have acquired the part but done nothing- since it still works, and maayybe the sound is a bit lesser now. 08 and 40k miles on odo. i let it chirp until it totally breaks
