Hi guys, unfortunately I had to find out at yesterday’s weather controls (27 degrees) that the air conditioning system no longer works. This went off independent noises and no longer cools. I had the problem about 8 months ago. According to the workshop, the air conditioning system had no more contents and the system was refilled again with a color contrast so that you can see where a leakage or damage is in the system. Can I personally use a suitable lamp or similar se I have the assumption that it is the capacitor. This can be quickly checked and replaced. Or should I simply drive to the workshop and have it done?
