Take off the relay ( white color ) Tapping alittle harder , and placed it back, It's work for me. If not you may replaced it . But find out first your Compressor is good or not.

I have a 2003 toyota corolla. My AC would blow cold air for a min or two then when the compressor shut off it would no longer blow cold air or come back on. A new compressor was put in it but it did not...

the ac clutch relay is the problem. It is located in the under hood fuse box. It is a $10 part. The relay will make a clicking sound when activated but the contacts inside are burnt causing no electrical flow to the ac compressor. Simply unplug and replace. The relay is labeled M/G CLT .

replace or blow out the cabin air filter as well. It is located behind the glove box. Instructions are in your owners manual.

I would check the AC clutch relay. It has a bad habit of going out. It is located in the fuse box under the hood next to the battery. It is the smaller rectangular relay nearest to the negative battery post. It is labeled M/G CLT. You can swap out a similar relay and see if it fixes the problem. New relays can be purchased from for $11

2003 Toyota corolla airconditioning not coming on

First, you have to check if there is enough gas in the system in order to make the compressor run. A depleted charge will keep the compressor from running. Feel free to email me for location of fuses and relays.
