Window & Air Conditioning System Problems

[Auxiliary]

Hello everyone!

 

I hope you're all doing well.

 

Window Issue:

 

Upon turning the ignition key to position 2 and preparing to close the driver's door, I noticed a peculiar noise emanating from what I believe to be the fuse/relay box. Please refer to the attached image circled in red.

 

Initially, when the windows were still operational, they emitted a jerking noise when I attempted to lower them. Additionally, the main switch on the driver's side seemed to be malfunctioning, while the individual window switches on the other doors operated more smoothly.

 

However, in recent weeks, the windows have completely ceased to function. None of the window switches are able to operate them.

I've already checked fuse 11. Online sources suggest that this problem may be caused by a short or break in the cable harness in the door. 

 

Air Conditioning Issue:

 

I have the Climatic AC unit.

 

Approximately two years ago, I had the AC gas refilled at a local garage by personnel I trust. Despite being assured of its airtight condition and being shown a receipt, I remained skeptical.

 

However, the AC worked like a charm, producing very cold air. About a month ago, it began emitting a hissing noise, and its cooling efficiency noticeably declined. Now, it feels as though there may be no refrigerant left in the system. Could this be a classic symptom of a small rock puncturing the AC condenser?

 

Thank you in advance for any assistance.
