Where do I locate the AC fan relay

Good morning,

I attached a picture of the location for you.

Roy

This is what I have as a fuse box. I am not understanding why it looks different than the diagrams I have seen and you sent. Should I be looking somewhere else for that relay?

Thanks for your help.

Okay, thanks.

That is called the totally integrated power module or TIPM. The relay is electronic and inside the unit. It is not serviceable.

It provides power to the compressor once it sees the signal from the pressure sensor.

This is a very common failure for this issue.

So what should I do to get this fixed?

You need to be sure you have a signal from the pressure sensor to the ECM. You will need a scan tool to check that.

Make sure the pressures are correct. With the system at rest, the pressure should be equal on the high and low sides and about the temperature outside.

If all that is good, replace the TIPM.

Okay, I will try that. Roy, thank you so much for your time!
