@737mechanic thank you for replying. I couldnt find that answer anywhere, nor could i reach their customer service dept to ask. Ive replaced my entire ac system and still, it's not blowing as cold as it should and i cant keep paying mechanics to throw parts at it. Need to do it myself just need the right tools on a budget. Thanks again!

@@accurateexteriorsco Just keep in mind as long as the manufacturer allows those actuator values to be read this scanner will do it. What year, make, and model, are you working on?

@737mechanic 2014 gmc sierra 1500 slt 5.3L. After all ive done and had done to it, i feel like the only thing left it could be is that the blend door isnt closing off completely from the heater core....i was this close to cutting the lines and putting in a heatercore bypass valve . But i need to actually diagnose what the problem is before hacking into my truck, so i need a scan tool that can help me with that on a budget.

@@accurateexteriorsco One thing you can do is use pinch off pliers and pinch off the heater hose. Also make sure when you get a scan tool to look at the evaporator temp sensor and it should be around 40 degrees, that will at least tell you the A/C system is capable of getting the evaporator temp low enough to cool.
