307 Power cut when A/C/Heating is turned on

Hello. I'm new to the site, I couldn't see anyone who had a similar problem among the topics. First of all, I apologize if there is a topic that I missed and if I opened a new topic again.

My car is 2006 model facelift body 307, 1.6 hdi 90 hp, analog air conditioner. After the air conditioner maintenance in the last summer, when the weather got warmer, I started using the air conditioner, and after working for a short time, I realized that my electricity was completely cut off in the air conditioner control panel. I was in a different city due to the holiday, when I showed it to an air conditioner service, he checked the heater motor, he said there is no problem, he said that there was a problem in the fuse box and as a temporary solution he connected a fuse and bypassed it. I have been using it this way since September and there is no problem, but since the electricity comes directly from the battery, the heater or air conditioner continues to operate when I turn the ignition off. In fact, the battery was discharged because I left it on many times. When I remove the fuse that was put in between a few times, it works normally for a short time and then makes the same interruption again. If it works on tier one and I'm lucky it works for an hour or so. In the next stages, it cuts the electricity again after 10-12 seconds.

The power outage only happens on the heater/air conditioner control panel. Windows, mirrors, horn, lighting systems, components such as abs, airbag and steering pump still continue to work actively when I check with the device. When I consulted with several electricians and air conditioning services, they said different things. I am attaching a photo of the place where the insurance is placed.

If anyone has a similar problem or has a solution suggestion, I would appreciate it if anyone could help. Thanks in advance.

hello, sir, did they look at the heater resistance? Usually, such problems are caused by this part.

I showed it to the air conditioner service I go to all the time, he said it's not for us, he directed me to a different electrician. He said that the chest should be removed. A different air conditioner service also said that the chest will be removed and looked at. I have come across people who either do not know the job or are busy, they want a lot of money for workmanship. If I'm sure of the fault, I'll dismiss it as well, but they're not the best either.

masters have flown bro possible problems.
