The car air-con gave up on Saturday. I thought it was a fuze problem. Nope fuze is ok. May be its the relay. Checked what I thought was the air-conditioner condenser relay. Looks ok. Turn the engine, the air con is back! Hurray I thought.
Later in the evening it stopped working for good. The next day, Sunday is a Public Holiday, so is Monday. Have to endure 2 sweltering days driving with the windows down. Reminds me of my childhood days on the old SBS or Tractor Motor buses.
On Monday night, I managed to noodle the electrical diagram for the heating and cooling. Turns out the blower motor is directly connected to the mains and ground. There are a couple of resistors to adjust fan speed, basically thats it. I know the electrical cabling is good, that means the bad news, the blower fan is dead. More noodling, lots of people say it is a simple repair job. Only problem is that I can’t remove the dash. Sleep on it.
The next day I have given up and was going to drive to the agent to get it fixed. Wait a minute, agent for a simple blower motor switch is simply not worth it. More noodling and found a shop near the office.
Thank you Precision Auto Air-Conditioning for being light on the wallet, we now get cool air with our drive.
