The AC work perfect and out of nowhere the air stops cooling and then cools back again and so on, after a couple of minutes of this happening the car starts over heating.

The air con not working and the heater also. But the heated seats are heating up.

The drivers side headlight is out. Replace the headlight assembly but the headlight is still out. Need wiring system for it so I can replace whatever is wrong. The heat isn’t working in the passenger side of the car and it is weak on the drivers side.

I own a 2013 VW Jetta GLI. Recently, the driver’s seat was removed for upholstery repair. After reinstalling the seat and reconnecting all wiring, the airbag system and seat heating work correctly, but the power seat adjustment functions (forward/backward, height, etc.) do not operate at all.
Could you please advise on possible causes or provide guidance on resolving this issue?

Heater won't turn on at all
