2nd Gen Non-Engine/Transmission BD Pressure Lock and vacuum problem?

[canblue]

Since I have had the BD Pressure Loc installed, the ventelation system has been acting up. Every time I slow down and stop, the system routes the air flow to defrost. Is there a problem with the vacuum system or installation? Anyone else experienced this problem?



The system appears to work properly and I am very satisfied with it.

The pressureloc uses the vacuum system to activate. It does not use alot of volume to activate it. It sounds like a large leak may have been created in the vac system. The vac system hold vacuum for quite along time after the engine is shut off. I would suggest that with the engine shut off look at all the vac lines starting at the pump and work your way up the fire wall. Pull off one of the caps that plug the end of the vac line. should have a small amount of Vac present.



Best of luck.
