ACC only runs when it wants to. 700

My fan in my 87 760 only runs when it wants too. It will run when in the defrost mode, but in all other modes it runs intermittently. Also it seems to be stuck in the warm to hot mode when it is running. And the vacuum door will go to heat when the Thermostat is turned up but it will not go in the other direction when it is turned down. AC compressor is working and the lines coming off it are cold and hot so I know it is cooling but it seems to still be mixing hot air in. Does this sound like a vacuum or electrical problem. There is a pink wire w/ a female bullet connector behind the glove box near the vacuum switcher that is disconnected but I can't find the other half of the wire.
