So the other day I added a can of refrigerant to try and boost cold from air conditioner used it that day. Next time I started it air conditioner did not come on neither indicator light on buttons air conditioner and recycle air works. I checked under-hood 10 amp air conditioner fuse okay and inside fuse for HVAC okay! Also switched under-hood relay. Now what? Is there another fuse to check?

Have you tried wiggling around the blower speed switch? I have seen those effect the lights on the buttons.

Okay the lights are on when fan is on but still no cold so I guess I will have to start at compressor and trace backwards.

The gas you put in could have leaked out. What are the high and low pressures? Also you do not know how much was in before you added charge. Things we need to think about.

System has never leaked much over long time I did put a can in last year or year before. Yes, I will take low pressure test to see what it reads if I get compressor to run.

We need pressures without the compressor running? Since the compressor does not turn on. Air conditioners leak can change at anytime. I have had suction hoses off the compressor pop while I am charging the system. Scares me every time, lol. So leaks can get bigger at anytime.

Let's do that and see if there is enough pressure in the system to the compressor come on.

If I get a hiss I am confident it just needs Freon, no serious leaks.

Get some with AC dye in it but without stop leak in it. There's no shield on the exhaust manifold so all the heat radiates to that hose.

That hose is one of the most common places to leak. Also make sure the hoses on the AC compressor are tight. Especially the top hose that on can loosen up over time.
