Question es330 installed stereo, ac not working

I installed a Sony XAV-60 dvd receiver into my Lexus ES330 using a Metra TYTO-01 integration adapter. My problem is the air conditioner did not work after installation was complete. I disconnected battery and cycled ignition twice per Metra tech support. The ac does then work, but will start blowing hot again as soon as I try to adjust temperature or any ac controls. Does anyone know what is wrong?

Is the A/C green light flashing and/or going out??

I'm guessing your car is a 2004??

Pop your hood. Open the Fuse/Relay box and locate "MG CLT Relay" If the part number on the Relay is:90987-02022 go to a Toyota Dealer and get Relay Part#90987-02028.

Your problem should be solved if thats the issue you are experiencing.

The green ac light stays on. Also not stated earlier, the display reads cold after resetting. As soon as I try to adjust temp to 65, the unit blows hot.

Make sure you didnt knock anything loose behind the AC unit.
