heater part two - ZR-1 Net Registry Forums

todesengel · 05-10-2010

Ok, heater core has great flow, but it sems the a.c always runs no matter what the set temperature. I am assuming it is a blend door issue.

Two questions;

1) Can anyone tell me where the vacuum check valve is for the actuator that controls the stepping motor for the blend door?

2) Can the blend door position be manually moved without major disassembly of the dash?

TIA
