Dash AC / Sight glass

[Jay Darst]

Shane,

When I switched the dash a/c over to 134, only "hardware" update was
a new expansion valve.

Pulled a vacuum on it for a while, then filled system with 38oz of
R134. Works like a champ!

5 pounds is a lot more than what I used. Did you repace the roof top
condenser with something larger?
