This has happened to me as well. The fix is a simple $18-$25 part, the Resistor Block, which is located inside the back Firewall adjacent to the Blower Motor Housing. Two (2) screws and it pops right out. Easy to replace. This will usually go before the switch which is much more difficult to access inside the dasshboard.
