ok this is the deal..my blower motor resistor keeps going bad....this is the 2nd replacement in the last 3 weeks..... i dont know what the problem is, either the fuse goes out or the blower motor resistor stops working...

 

it's your blower motor. the blower motor puts too much current through the resistor.
my last blower motor killed the resistor after 8 sets of fuses.
a new blower motor is needed. never put any sort of grease into the blower motor, which will make problem worse.

 

Sounds like the blower motor itself is bad. It's failing and drawing to much power.

 

seems like a bad blower motor to me as well
