Recently installed a racing beat intake and took off my old filter box. Remember taking 2 relays off a metal bolted to the engine bay. Now my AC is not turning on/cold. 1 relay is for Clutch and the other is for compressor. AC Fan works but you can't hear the clutch engage and the compressor is not spinning. Same thing happened to my brother's friend who recently installed turbo and had to removed his intake for the turbo pipe. His AC has same issue as mine. Are the relay not to ground anymore? Anyone done this? New Relay?

This is what the relay looks like it. They are just hanging now.

The AC compressor pulley will spin regardless. If the clutch engages, you will see/ hear it. There is only one wire going to the compressor, you have the relay locations correct. If the AC system is low, that is not making pressure from a lack of refrigerant, the pressure switch on the passenger side will not allow the compressor to engage in order to save it. The factory service manual has an easy-to-perform diagnostic on the system to confirm where the problem lies. I did this to my '99. You might find it online.
