glad to be back boys! im losing my patience with the ol lincoln and the AC isssue. it works, but only on the passenger side when im driving, and one both sides at an idle. sometimes its not cold at all on either. its embarrassing, when someone is with me and they are hot.. well sorry the AC dont work. its a lincoln and all, but... ugh. and compressor is dragging. that might be due to a low level. i'll fix that after i fix this DCCV. i know its been posted a dozen times. but i want a difinitive answer to my own questions. 1. how much am i looking at for doing this myself? time and money wise. 2. should i buy the original Motorcraft valve? 3. need any special tools? 4. why must it be 93 degrees out right now?
