No heat or cool don't matter what temp I put it only blows the temp air from outside. If it's 85 I get 85 degree air if it's 65 I get 65 any insight before I go recharge and evac system?
any insight before I go recharge and evac system?
Usually, a no-heat problem is due to air in the heater circuit, which is usually because of degraded plastic cooling system parts.
Some more information is needed for good help here.
Is this the V8 or the V6?
Did the heat and AC work before and then it stopped? Did both stop at the same time? Or, did you just get this car and neither worked when you got it?
It's the v8 and I do know I need to replace upper radiator hose due to small leak.. The Ac did blow cold when o baught it but went out shortly after. Attempted to recharge system using Ac pro and only got a pressure of 10 psi on low side, and the system wouldn't take refrigerant. Even if the car is running hot due to the coolant leak, no hot air comes into cabin just the temperature air from outside. Hope this helps
Okay I know what you're talking about. Now to find the leak.. Do you know of any common issues with leakage on the LS?
Still talking about the AC system right?
A leak from the "o-ring" for the control valve at the back of the AC compressor seems common. (Both of mine have done this, one of them twice.) If this is where your leak is, it is bad news because most of the compressor oil leaks out first and the compressor can self destruct and mess up the rest of the system. Other than that, check all the places that lines connect. It should be oily where the leak(s) is/are.
Yeah still on the Ac.
The compressor is located on the pass side front of engine near the high side port correct? I know for a fact that it isn't kicking on. If it is the o ring leaking would replacing my compressor solve my issues or would it need to be a complete overhaul since you said that the compressor may self destruct and cause damage to the rest of the system? I'm hoping I didn't bite off too much to chew here.
