Check engine light on , told it was a 315 code and the evaporator val may have to be changed. Is this easy to do and where is it located

Driver window switch shuld be changed , shop wants to change the complete pad instead of just the switch. Any info on how to change switch or pad.

I think your talking about the EVAP system and not the evaporator. The EVAP system can trigger a code if the car is fueled with the engine running. If this is what caused the code, it will go away next time the the EVAP system runs a system test. It is the system that maintains control of the gasoline vapors generated by your car. The vapor from the tank is stored in a charcoal canister in the engine compartment and then at the appropriate time the fumes are run thru the engine and burned. You code can also be caused by a leaking vacuum line(s) going to the valve on the charcoal canister or the EVAP valve itself.

You should be able to take the door pad off yourself fairly easily and replace just the one switch. You can get one at the dealer or at a junkyard. You may even try some online sources like FCPGroton.com (Nick Bauer).
