Since i bought the car i have had a problem with the ac not working. After doing some quick research it seems the "EC" light is stopping the compressor from activating. Before i got around to fixing that problem another problem arose that seems to be another pain. One day after having my car parked for about two hours i came outside to still have my blower motor still running. The only way to deactivate the blower motor was to remove the fuse. After doing some research i saw this was a common problem and the culprit is usually the blower motor resistor regulator. I have changed that part and that did not solve the problem. I took it to my mechanic and he determined the plug that sends juice to the regulator and blower is getting a constant power even when the climate control is off. the plug should only get power when the climate control is set to off. The method of me pulling out the fuse eliminates the possibility of a short somewhere between the blower and the fuse and that there must be a problem somewhere between the fuse and climate control. Any suggestions before on a possible fix without having to replace the climate control.

As far as your EC Light all you need to do is add gas to the system. The EC light being on is a safety for your compressor so it does not burn out. Toss in a can of R124a and the light should go away. As far as that unit itself no need yet to replace the unit. Did you run the codes yet? Did your mechanic run codes too?
I ran the test and this was the results
