Hello maybe someone can help me locate the high and low pressure switches on the A/C. I just bought a 99 tl and the guy told me that their is a melted wire on one of the pressure switches. I just bought the TL and Love, It has a 100k miles on it, I bought because I wanted something good on gas that still was comf and you woul dnever know this car had 100k miles on it it drives awesome and still gets 26 mles a gallon. My only problem is that about once a week when the air is on Max because I live in FL and its extremely hot I need to put it on Max. When the car is driving about 35 to 40 the car will just shut down, Weird all I have to do is put it in neuatral and restart it starts imm, Maybe its something differant but the guy I bought it from thinks its because of a melted wire on one of the pressure switches on the A/C. Any input would be great.
