Open the underhood fuse box next to the driver' side fender. The relay is the smaller one nearest to the negative battery post. The relay is marked M/G CLT. Simply pull it straight up, wiggle a bit if you have to. Then plug in the new one.

Tip

Toyota AC Light flashing


Here is a real money-saving tip for you Toyota owners, with a problem of your AC light flashing on the instrument panel, when the AC is on.

You may also expericence a 'no cooling condition', also.

This info pertains to the following Toyota vehicles:

2001 thru 2004 Camry, Echo and Celica

2002 thru 2004 4Runner, Corolla, MR2 Spyder

2003 thru 2004 Highlander, Matrix, Sienna and Solara

Toyota is aware of this situation, and has produced a technical service bulletin to rectify the AC light flashing condition.

What has happened here is that the AC relay
(noted as the 'AC MG CLUTCH' relay in the relay box, under the hood)
has gotten weak over time, and is not properlying transmitting power to engage the AC compressor clutch.

Toyota has an improved relay available, and can be purchased at any Toyota parts department.

The affected relays have the following part number stamped on them:
90987-02022

The improved relay part number is 90987-02028

The repair is quite easy, all you have to do is identify that you have a 90987-02022 relay. If so, purchase a new relay, 90987-02028, and simply remove the old one, and fit the new one into the relay box.

Once the new relay is installed, the AC light flashing problem will be cured.

We hope that this tip saves you the money that you would have paid a repair facility to daignose the problem for you.

Thanks for reading my Tip!

All 4-thumb helpful ratings and testimonials (VERY HELPFUL) would be greatly appreciated.

2004 matrix ac inop


Most of the Toyotas in your year range have an updated AC relay. If the system is full of freon, the pressure switches are operable, try replacing the relay.

If the system is low of freon, it won't allow the compressor to start up.

There is an easy way to check the compressor clutch, but I can't explain it unless you understand how a relay works and which pins to connect in the relay box.

I have a 2004 toyota corolla ce. i cant seem to find the a/c clutch relay.


look under the hood. Open the fuse box on the drivers side fender. The relay will be the one closest to the front of the car. Labeled "M/G CLT". It is very near the negative post of the battery. If you turn on the AC you can feel the relay clicking on and off. To test you can swap out another relay in the fuse box. The AC relay is availble from Rockauto.com, $11.

A/C blows hot air. 2004 Corolla SE


You may need to recharge your AC. The AC clutch relay seems to be a high failure item for this car. You can test by swapping relays under the hood. The AC clutch relay is located next to the negative battery post in the fuse box under the hood on the driver's side fender. It is the smaller relay marked "M/G CLT". This is available from Rockauto.com, $11.
