BREAKTHROUGH. The vacuum line on the door I believe is the blend door was to tight, i backed it off just a hair and now the door opens. I also found the switch on top of the receiver drier is bad. Question? are the low pressure and the high pressure switches the same switch, I know there are two switches, but is the switch itself the same? Because I can only find the high pressure switch at the auto parts place.......

I don't know for sure if the two switches are the same but I doubt it. If you can't find the low side switch at any auto parts, try an A/C parts distributor. BTW on your first post you stated that at 94* at 750 RPM you had 44 low and 265 high, my chart says you should be at MAX 43 low, 270 high.

That would REALLY be helpful . . .
