I need to know the location of the low pressure switch on the AC system?? Any help would be appreciated Thanks!!!

 

It is on the evaporater core, inside the box. It is not that hard to take out the whole evaporator. If you have a service manual, it shows it.
What is wrong with yours? They do not go bad very often.

 

I don't think it is bad. I just bought this truck and it is my first Toyota and I don't have a manual or anything. I know the system is completely empty of freon and I don't know if the compressor is good or not. I just want to jump out the switch and run the compressor just for a second to see if the AC controls and compressor will even kick in. That way at least I will know if it turns or not before I vacuum it down and charge it only to find out the compressor won't even turn. I'm going to replace the dryer at a minimum. Thanks for the advise.
