Hi. Any idea what went wrong if this happen to myvi AC.
1. AC is very cold when the car is moving 40km/h and above under very hot day.
2. In a very hot day, the AC compressor hardly stop. It will stop for a couple of seconds only after running for a minute. This happens when the temperature is set to middle, with blower at 2.
Here comes the problem,
At very hot day, when come to bad traffic, which is about 15 minutes of not moving, the air con cooling efficiency will started to drop. the aircon compressor still running at this time.
If the car keep stucking at bad traffic for another 3 minutes, the compressor will stop functioning. AC blower will give ambient air only. RPM will rise to 2000. The RPM will only back to normal idle when the AC is switch off.
Wait for 3 minutes and turn on the AC, the compressor will start functioning again, and giving slight cool air.
The AC cooling effectiveness will only back to normal when the car is out of bad traffic.
Sorry for the lenghtly description as I was trying to describe the symptoms of the AC issue.
BTW, some may think it is due to faulty radiator fan, rest assured it is a new denso motor. The fan has been running at its own capacity.
5 out of 6 aircon service providers were trying to persuade me to get the whole aircon system changed. price ranging from rm1200 to rm2700. One buglar even told me that they can't flush my system as it will contaminate his machine.
thanks to bro boarulez
suggestion and advice i was able to guess what is the possible aircon issue and narrow down my search to get my aircon system fixed at very reasonable price.
I'm currently having the same problem as you.
