A/C Evap Thermoswitch questions
Posted 18 June 2007 - 03:17 PM
My question is wouldn't that damage something? Why would subaru put that sensor there if not?
Also, what is the part number for the replacement and can you get this part at autozone or checker, etc.

If the coils freeze up, the ability of the coils to absorb heat is reduced to nearly zero. By cycling the compressor on and off as needed, it keeps the coils from freezing, and therefor keeps the car cool.
You wont hurt anything by bypassing it, BUT basically the flow of air will stop and you would have a very inneffecient AC system, not to mention all the fuel you would waste.

It happens mostly if the outside air is cooler than the inside air and/or if the inside air has high humidity. The evaporator will form a solid ball of ice on it and it takes a while at low fan speed to unfreeze it. (I moved the switch because sometimes the thing won't go cold enough so I put a little heater on it.)

It can be replaced without opening the AC system
Do the national auto parts chains carry the item (Autozone, Pep Boys, Checker, NAPA, etc.) ? Do I ask for the switch for the Legacy or a generic item? Do photos showing the location of the switch exist (I tried searching this website on thermoswitch but no results).
