It’s not a difficult repair, but you have to place yourself under the dash board on the passenger side. You pry off the panel under the dash, and the big black can you see is the blower. The resistor pack is mounted under the dash behind the blower motor, and it is easiest to remove the blower motor first. You unhook the wiring harness from the blower motor and remove 3 bots that hold the blower motor in place. If this sounds like too much, a shop can do the job for you. If you are still game, let us know and we can tell you how to get the resistor pack out.
