The blower switch on one of my Legacies has ceased to operate in Positions 1, 2 and 3. Everything works in Position 4. I assume the problem is the blower motor resistor?

Can anybody give me a 'blow by blow' account of how to get at it and replace it please?

While you're in there, clean AC evaporator and housing with suitable tools.

You really can't clean the evap box out just through the hole for the resister pack. I guess you could look in, and see how icky it is though ;)

I had some leaves, pine needles, seeds etc. on the bottom of the box which I was able to blow out, and also sprayed some mold killer on the evap. It would be a different matter if the evap. core is all gummed up, but it's important to know that the resistor hole gives access to the evaporator.

The resistor pack is meant to be in the air flow for cooling; if the air flow is restricted in any way, the resistors will overheat and fail pre-maturely.
