I'm afraid I'm gettin' a tad confused, here. According to the first bit of info I found under "search" was that which has been posted by "jbaj007" above to which I refer, noting that there are 4 wires involved from the klima plug to the ice cube. Now the reference is 3 at klima plug and 4 at the relay. This makes sence since I had no voltage at the solenoid on the ice cube and therefore nothing works. So I guess at this point, I hope to hear from Benzmac as to what changes I need to make. I appreciate your response and thank you. Nick
