Hello-

2009 4G - TL Tech package
225,000 miles are running great... Just need to get the a/c going before summer heat hits!!

My A/C is blowing air but it isn't cold. My pressure tests fine.

My next step is to check the relay. I've seen lots of advise about switching relays in the fuse box to see if that fixes the problem.

A couple of question on this..

- Which relay should I use to test the a/c relay... My a/c relay looks slightly different than the others. Not sure if it was replaced with a different model or if it is really a different spec than the others.

Also, when looking at the diagram in the fuse box lid...I have no idea what the different symbols mean. Someone mentioned using the heated seat relay, but I have no idea which one that is. The fuses locations are all numbered but all of the diagrams that I've seen just leave the relay locations blank. Any guidance?

Last question - What is the part number for the a/c relay if I want to just buy a new one?

I'm finding a lot of information on the 3G TL but everything is a little cyptic about the 4G.

Thanks for any help or guidence.

 

The relay part # is: 39794-SDA-A03. I wish you luck brother, I am also having issues with mine. Even after replacing the compressor, and relay it blows hot air. Taking it back to the shop for the third time Monday.

 

Had a similar issue and it was a bad TXV valve (metering valve) and caused the low pressure hose to collapse.
