What is your question?
My A/C/heat unit isn't working. Tried just about everything but am being told it's the relay switch. I cannot find where this is located on the car.

The AC compressor clutch is controlled by a solid state output from inside the TIPM, totally integrated power module. (aka the under-hood fuse and relay block). You need a fully functional scan to assess the systems ability to command the clutch on. Your probably going to need a shop to assist you.
