Heater control valve
 Login now/Join our community

I have a 1985 Regal 31. The vacuum lines have all (4) broken off from the heater control valve. It’s a motor craft part #YH-380. I have not been able to find anyplace or anyone that can tell me what vacuum lines go to which port on the control valve. There appear to be 7 ports on the valve and there are only 4 lines in the coach. Need to find out what each port controls and do I need to block off unused ports. If I could find out which port the engine vacuum goes to I could probably ,by trial and error ,figure where the other lines go. Need help..

Sorry I cannot help you with the placement of the hoses. It does seem strange, the Regal (Chevrolet) chassis would have a Motor craft (Ford) control valve. The control valve in my Regency is a Chrysler product.
When Steve VW sees this post he might be able to help. MWrench may be able to get you in the right direction also.
