The water pump was changed a year ago along with the timing belt. I changed the termostat, my radiator fan switch, radiator cap, and rad flush, without success. At least the radiator fan doesn't seems to be kicking all the time even when the car is really hot. Last time I try to tested after I changed all this parts the rad cap blew up.
I will try to find the hi pressure switch and make sure is plugged.
I know the changed the compressor and fix couple of things but I'm not 100% sure if the eva core was change. I have to look in the paper work

Wish me luck!
