When you replaced that blower resistor, did you replace the wire harness also?
Where did you buy the part from?
You never mentioned that you replaced the harness 3 times.
You said you replaced the switch 3 times, which i think you meant to say the blower motor resistor(its not a switch though)??
So,,,what all exactly did you replace please?
If all you replaced was the resistor assembly, then you need to go to the dealer and buy a new resistor assembly AND the harness connector with wires coming out if it that you splice into the existing harness. It IS a very common problem and thats why the dealer will sell you both! NO parts store will tell you that!
The harness connector has poor contacts and they get hot and melt the resistor and the new harness connector corrects that.
did you replace BOTH parts #1 and #2 in the diagram below?
I think so also.
Part #1 is what is causing the problems. We have replaced hundreds of them with this exact same problem :-)
You can only buy that harness from a dealer though and you should buy the resistor assembly from them also.
We have went round and round with this problem for years and GM finally figured it out!

Most likely the leak is coming from the valve cover gasket and is quite a bit of labor involved to replace it. I have seen these leak for years without getting any worse so as long as you just check the oil every time you gas it up you will be fine for MANY more years! Very common and if it were mine i wouldnt worry about it for sure unless it started to leak a lot more but that is doubtful. You can just top it of, no need to change it unless its due.
Disregard that last [post. It was for another question :-)
