Below the battery there’s a relay box inside there starting from the right hand side there are 2 red relays ( bigger ) and 1 black relay . If you take out the relays and look at the diagram at the bottom of the relay they have numbers on it . No 85 is ground . Take a small gauge wire and ground the 85 pins from the furthermost right relay ( ecm relay ) to the third relay (smaller narrower black relay ac compressor relay) this will force your compressor to turn on and fans should turn on as well if this works and fans and ac works then it’s your ecm that you need to replace . Be careful that the wire only touches those pins and nothing else that’s metal . This should hold you over through the heat . If your ecm needs replacement there are lots of places you can mail your ecm they can clone your ecm and copy the information on another one and mail it over and you just plug it back . If you go that route you will save about 900 dollars compared to a Indy shop or dealer as they will charge you anywhere from 1200 to 1500
