2007 EL no heat or AC

[Gregg Eshelman]

Pretty sure the AC has a leak. Last summer I had to keep topping up the 134a to keep cool-ish air coming out the vents.

The last time I needed heat this year I got only cold air out the dash vents.

You say topping off a/c, just a few ounces or pounds?

An AC leak would have nothing to do with not getting heat, it's not a heat pump like a home system. Heat is from engine so maybe diverter stuck in the cool position? That would give you no heat and if there is an AC leak, would give you minimal cooling.

Just a little at a time but still not much cold air.

Is there a common diverter or blend door failure in this generation?
