Lexus: Ok I have a customers car that they bypassed the a/c

Customer Question

Ok I have a customers car that they bypassed the a/c 1999 Lexus es300. So I went threw and cut out there mess at the a/c pressure switch that's where they had another relay wired in and just had to shove a red wire in the abs relay spot that they also pulled out. Totally wrong I know, But I found that there was no ground to the a/c clutch relay so after doing some test it lead me to replace the a/c control head with a Good one. I did and same thing a/c light flashes and I also replaced the Relay. But did fine out there was no freon in the car so I put about a half a pound or so just enough to get the Compressor to kick on but still not working.
