Value checker point please help

I just replaced the lines to and from the AC value checker point. Which is located at the top of my supercharge going from there to the back of along the fire wall do to the passanger side behind battery where the checker point is. Fomr there down along the front of the rad to the filter ball.


I put the checker value in and pluged the top hose and bottom hose into but we cant seem to locate the one coming off the side. If you have any ideas please drop me a line

Welcome to AF.

It would help to post the year of your Regal.

I'm confused as to what are are talking about. AC value checker point??? :confused:

What check valve are you referring to? The line that runs from the top of the supercharger along the firewall by the battery and to the firewall with the main wiring harness is accessory vacuum for the HVAC system.

If you have a pic post it to show what you are talking about because I am sorry what you have said so far does not make sense or not clear enough to provide any reasonable assistance. The valve on top of the supercharger has two outputs. One to HVAC accessory vacuum and the other to the supercharger boost valve.
