Hello. My name is Toyota Ed.
Welcome to FIxYa. Please allow me to assist you.

I assume that you want to clean the coils in the AC box under the dash, correct?

We have used many, many different products, but we have found that Toyota sells a very nice product that works the best. All you do is buy the can of AC cleaner foam from a Toyota parts departement, and insert the tube from the can into the AC condensate drain tube. Empty the contents of the can into the tube, and the foam will clean the coils, kill all the mold, and you will avoid having to pay a lot of money to have it removed and cleaned. We use this product a lot, and run specials on it at this time of the year. There are other similar products, but the Toyota stuff seems to do the best job.

Thanks for choosing FixYa for assistance today. I hope that my assistance proves useful to you. If so, a 4-thumbs rating would be greatly appreciated.

Have a great day.

Whistling sound from auto ac ducts

The whistling could be an indication of lack of air flow which will cause the evap coil to frost. The frosting could also be an indication of low refrigerant. As a quick & dirty test, here's something to try. After the system has been off long enough for the coil to completely thaw, set the thermostat for "fan on" & open the door to the air handler (or furnace). If you have to pull hard to get it off & air rushes in thru the door opening, you probably have a return air problem.

Toyota corolla 2003 air conditioning green light blinking and cold air not blowing

You've figured out by now the blinking light means the system has a problem. You'll need to find out if the system is low on freon or if a relay or electrical part is failing. The cooling fan could also be failing to come on, which would make the high side pressure exceed the limit and shut down the system.

How and what to do the tuning on 2003 toyota corolla s?

Plugs, air filter, pcv Valve (located in valve cover) this valve is really important relieve buildup pressure, a clog pcv can create oil leaks, an open pcv can create a hard to start condition. Clean Throttle body and clean battery terminals. Note, toyota uses Japanese plugs DEnso, etc, when people go to autozone they love to give them bosh plug after some months of operation the plugs fail to perform properly giving low percentage missfire and creating fuel economy problems.
