AUX Fan problem and resistor question
I have been having problems with my AUX fan not working in both mine and my moms 300e's. I have narrowed it down to the resistors or whatever senses the temperature and tells the fan to turn on. I am attatchign a picture of the resitor from my car (looks pretty bad doesnt it?) and my moms is in similar condition although not cracked and corroded as much as mine. Is there a way to test a resistor without a multimeter? Also, I will probably ordernew resistors to see if that works because I did have mine work for a couple seconds after I bypassed the resistor and let it idle for about 15 minutes to build the heat up enough to trigger the fan so I know the fan works. I also tested the van with a 12 volt battery charger and both work which is nice that I dont have to spend $300 for each fan.
Any ideas on what is wrong? Resistor, turn on circuit? Something else? Any help would be appreciated.
