OK so here is my issue I have heat when the car warms up, it stays hot untill you start driving then somewhere around 40mph it begins to blow cold(ambient outside air temp) sometimes heat will come back if I return to idle or low speed. I tested the sampler motor (can hear it running with ign. in on position) & it will hold a small piece of TP to the intake grate. Lots of ppl pointed fingers at the mono valve so I removed the connector leaving it in what I believe to be the "open" position. Same symptoms. Thinking I may have a wacky vacuum issue I tried running the heat in park and held the rpm's between 2500-3000 heat stayed working just fine..... I have noticed that the blower motor sometimes ramps up and down when on the high setting is this normal? or perhaps a sign the CCU is dying.....PLEASE HELP!
