'02 Caravan resistor block ok but fan still works on high ..

Hello,
I changed out the resistor block in my 2002 Dodge Grand Caravan about
7-months ago due to a bad resistor block (front fan only working on
high). Now again the fan is only working on high. I took out the
resistor block and this one appears to be ok. I can't say I see any
damage to the resistor or coil. The only thing I could say is that one
of the coils has a blue-ish hue to it. Would this indicate that the
resistor block is toast, or is there any thing else I should be
looking at?

I did look at the wiring on the 2-plugs going into the resistor block
and they appear to be in good shape. I also looked at the 40-amp fuse
and it also appeared to be ok.

Thanks

Just for fun, I took the blower resistor apart on my wife's 1999 Dodge
Ram Van as I had to replace it for the fourth time (it was 0 degree's
outside and I had a cold). I used a multimeter on it and found the
little thing that looks like a resistor was open (the finest of the
little coils was also a bit blue). More investigation found it to be a
thermal fuse. With the information I found on the fuse I found the
manufacturer. I'm going to try to find prices and a distriburtor to see
if it's worthwhile to replace it (the next time it goes out). I got the
replacement blower resistor at NAPA for a bit over $20 with tax, so it
may not be worth the effort.
