I recently replaced the blower motor resistor and the resistor connecter due to the blower not working at all. Now the blower motor cuts off at the max (5) setting. I back probed the blower motor connection and I have voltage and it switches all the way up to 4. As soon as I set it to 5, the voltage drops and the blower motor cuts out. I also replaced the heater/ac control module thinking that was the only possible solution but it still cuts out. Both Contol modules (old one & new one)cut out on the max setting. I have also tried 3 different resistors and still have the same problem. Any direction given will be greatly appreciated.
have the same problem?

Try checking the 40 amp fuse at the under hood fuse panel, here is the fuse location and a guide to help check it.
