I could really use some help in this area fellas the solenoid that controls vacuum to the heater control valve is losing power intermittently causing the air to get hot for a couple seconds then it gets its power back and air is cold again. Anyone ever seen/heard of this? What sends power to these solenoid? Please help.

Sorry for updating an old thread, but maybe this is useful for someone else too. Power to the Hvac/Resirc valve comes directly from the CCU. See the following thread for the schematics and look at IC8 and IC4 that controls it, sounds like one of them is faulty.
