The air conditioner in my car was not working properly for about two months, as I could not turn it on and it would stop working by itself in the middle of the day. I took it to a repair shop in town because I couldn't turn it on at all for the past week or so.
However, after a quick check of the relay and wiring, they replied, "We don't know. Take it to the dealer in Cagayan or Cebu. Originally, I didn't expect them to be able to find out what they were looking for, since I had already looked into those areas...
I decided to check it out again myself, especially since it is a life-threatening situation, such as heat stroke, when an air conditioner in operation stops by itself.
This is the HVAC control panel that was removed This was further disassembled to remove the circuit board on which the electronic components inside are located. The operation of the switch is normal, so I suspect cracks in the solder, etc., which are difficult to detect visually, I cleaned it up with a desoldering wire I ordered from Japan and re-soldered it.
When we temporarily installed the compressor and checked it, we found that the compressor, which had not been working at all, was working properly!
The plastic of the hook part of the wire was broken during removal, so it was repaired with epoxy. Lotlot is very dexterous and reliable in this area.
I installed it in my car and tested it, and now I can turn on and off the air conditioner in response to the switch. I told Gigi I was done fixing it and he said, "1Million kissesBecause..."
