hi, i'm tired of my compressor cutting out while it's still not cold. how do i perform a mod to put a switch on the dash such that i can turn on/off the compressor at will? after all, it's practically hot all the time where i am...

understand from a prev post that there is some kind of valve/relay that is linked to the evaporator? will replacing that help, and what does it look like? my w123's a/c is a non-climate control type... thanks.
